WBBSE Solutions For Class 7 Geography Chapter 11 Continent Of Europe Topic D Polderland

WBBSE  Chapter 11 Continent Of Europe Topic D Polderland Long Question And Answers

Question 1. How is a Polderland formed? Discuss with diagram.
Answer:

Formation of Polderland:

The mechanism of reclaiming the shallow part of the sea or creating a Polderland is completed in five stages, such as-

1. Land consolidation with concrete dams:

In the first stage, the shallow part of the sea is bounded by reinforced and wide concrete dams. A ring canal is cut inside the dam in such a way that water from the enclosed area can be pumped into the canal and finally can be emptied into the sea.

2. Filling by mud-water:

This wetland is then filled with mud water with the help of a pump (formerly done by a windmill).

3. Drainage with the help of a pump:

In the third stage, when the mud stagnates at the bottom of the wetland, the water is pumped out into the sea through ring canals.

4. Cultivation of grass-like fodder:

In the fourth stage, the land is left for several years to reduce the salinity of the soil. Alfalfa, hay, clover, etc. grasses which are used as fodder, are cultivated to make the land suitable for agriculture.

5. Cultivation of crops and flowers:

Finally, different types of crops like wheat, barley, beet, oat, etc., and different types of flowers like sunflower, tulip, cosmos, gladioli, etc. are cultivated when the land is suitable for agriculture.

Thus the land recovered from the sea becomes usable in a few years.

WBBSE Solutions For Class 7 Geography Chapter 11 Continent Of Europe Topic D Polderland

Question 2.  Where are the polders concentrated in the continent of Europe?
Answer:

Polders concentrated in the continent of Europe:

  • Most of the polders in Europe are within the political boundary of the Netherlands. Almost 40 per cent of the total land area of the Netherlands is polders.
  • The team ‘Polderland’ means land reclaimed from the sea.
  • In the northwest of the Netherlands, in the shallow part of the Gulf of Zuider Zee, the vast lowlands that have been recovered by removing seawater with concrete dams are called ‘polder land’.
  • To the north and west of the polders lie the North Sea and Belgium. Its area is variable.

Question 3. What are the special characteristics of the topography of the Polderland?
Answer:

The special characteristics of the topography of the Polderland are as follows-

  1. Though the Polderland are extensive plain lands, because of their average elevation being below sea level, they are classified as lowlands.
  2. The Polderland are protected by concrete dykes-in case these dykes collapse, the polders will be reclaimed by the sea. So, during times of rainfall, the water that accumulates in the polder land are constantly pumped out and carried away by canals.
  3. About 90 percent of the Polderland is about 2 to 3 metres below sea level.
  4. The polders are plains with a lot of swamps, marshes, and primarily clayey soil.
  5. The northeastern part of the Polderland is known as Groningen, the south and south-eastern parts are called Zeeland and the portion between Groningen and Zeeland is known as Middleland.

Question 4. Classify the polders into physical regions.
Answer:

According to the topography, the polders can be classified into three regions-

  1. Groningen,
  2. Middleland and
  3. Zuid Holland.

1. Groningen:

  • The northern and northeastern parts of the polders are called Groningen Friesland and Overijssel.
  • This region is below the sea level.

2. Middleland:

  • The west and central part of the polders of the Netherlands covering Noord Holland and Dordrecht is known as Middleland.
  • The elevation of this region is slightly lower than the sea level.

3. Zuid Holland:

  • This is the southern part of the polders.
  • The elevation of this region is the same as the sea level.

Question 5. Write about the climate of the Polderland.
Answer:

The features of the climate of the Polderlands are as follows-

  • Effect of warm ocean current: Though the polder land are located in the cold temperate zone but the influence of the warm North Atlantic current makes the climate moderate.
  •  Temperature: Winters are moderately cold with an average temperature of 3°C. Summers are also moderate, with an average temperature of about 16°C.

Answer:

Agriculture in the Polderland is carried out in two main ways-

1. Mixed-type farming:

This type of agricultural practice requires skilled farmers, the use of advanced technology and certain other factors-all of which are available in the Netherlands. As a result, this type of farming is prevalent and is also commercially viable.

2. Greenhouse farming:

Vegetables and greens are grown in greenhouses in areas where the temperatures are low and the sun rays always fall obliquely.

Question 8. What are the agricultural products of the Polderland?
Answer:

The main agricultural products of the Polderland are as follows-

1. Animal fodder:

To reduce the salinity of the soil, crops such as hay, clover and alfalfa are grown on newly reclaimed soil.

2. Food crops:

Once the salinity of the soil has been reduced, the soil becomes very fertile and yields high-quality food crops like wheat, oat, barley, potato, mustard and so on. Animal rearing is also done here.

3. Flowers:

Flowers such as tulips, cosmos, gladiolus, and daffodils are cultivated on huge tracts of land here. These are sold in other parts of the world. So, flowers are an important cash crop for the farmers of this region.

Question 9. Explain why agriculture is done with the help of greenhouses in polderland.
Answer:

Agriculture is done with the help of greenhouses in polder land:

  • The polders of the Netherlands lie in the cold temperate region that comes under the British Isles climatic type. As the summer temperature of the region is 16°C and the winter temperature is an average of 3°C, the region is always cool.
  • In this type of climate, nothing grows well apart from wheat, beet, cabbage and a few other crops. So, greenhouses are used to regulate the temperature and grow grapes, cucumbers, melons and such other fruits.

Question 10. What are the mineral resources and industries in the Polderland?
Answer:

Mineral resources and industries in the Polderland:

  • The main mineral resource of the Polderland is natural gas. Groningen, situated in the northeast of the polder land, is the main area from where large quantities of natural gas is extracted.

Question 8. In your opinion, in which direction is the general slope of Europe and why?
Answer:

The middle and southern parts of the continent of Europe are taken up by high mountains and dissected highlands and high plains. So, the land of the continent of Europe slopes in three directions-

  1. From the middle to the north
  2. From the middle to the south
  3. From the middle to the west

Reasons:

We know that rivers usually flow from the higher lands to the lower lands. In Europe, the rivers flow in three directions which are as follows-

1. North-flowing rivers:

These rivers flow to the north from central Europe. The main among these are Seine, Rhine, Elb, Vistula and Oder.

2. West-flowing rivers:

These rivers flow to the west from central Europe. The main among these are Minho, Douro, Tagus and Guadiana.

3. South-flowing rivers:

These rivers flow to the south from central Europe, for example-Po, Danube, Dnieper, etc.

Question 9. Give a description of the north-western highlands or the western uplands.
Answer:

North-western highlands or the western uplands:

In the north-west part of Europe lies the mountainous region of the Scandinavian peninsula (Norway and Sweden are part of this peninsula), the mountainous region of Finland, the northern and central parts of the British Isles and the hilly regions of northern Ireland are all parts of this physical region.

Characteristics:

  1. This is a dissected plateau, separated by deep valleys and fjords.
  2. This is made up of old volcanic and metamorphic rocks.
  3. Several fjords and lakes can be observed in the coastlines of Finland, Norway and Sweden. That is why Finland is known as the country of lakes.

Question 10. Give a description of the northern and central plains.
Answer:

Northern and central plains:

To the south of the north-western highlands, lie the north-central plains that extend from the Ural Mountains in the east to the Atlantic Ocean and the Bay of Biscay in the west.

The southern part of the British Isles, the northern part of France, Netherlands, Belgium, Poland, the northern part of Germany, the western part of Russia – almost more than half of Europe falls under this physical region.

Characteristics:

  1. This extensive plainland has an average elevation of 180 metres.
  2. The main rivers of Europe such as the Rhine, Volga, Don, and Dnieper all flow through this region.
  3. The erosional activities of glaciers or the subsidence of land has formed several large lakes, such as Ladoga (17,700 sq. km) and Onega (9,700 sq. km) in Russia. Ladoga is the largest lake in Europe.
  4. A large part of the Netherlands i.e. the north-west part of this region has been reclaimed from the sea. This land. is known as polderland.

Question 11. What do you know about the central uplands of Europe?
Answer:

Central uplands of Europe:

In the south of the north-central plains lies the dissected plateau of the central uplands. Spain, Germany and France fall under this physical region.

Characteristics:

  1. Geologically, this plateau is quite ancient. Erosional activities on fold mountains which were formed about many years ago have resulted in the formation of this plateau.
  2. The erosional activities of rivers have made this entire region a collection of small, separated plateaus.

For example-

  1. Meseta of Spain,
  2. The central Massif of France and
  3. Don Massif of Russia, etc.

WBBSE Chapter 11 Continent Of Europe Topic A General Introduction Of The Continent Of Europe Short Question And Answers

Question 1. Explain why dissected plateaus have developed in central Europe.
Answer:

  • Millions of years ago, fold mountains were formed in central Europe. With the passage of time, as processes of erosion acted on them, the fold mountains became reduced to a plateau. In France and Germany, this is known as the Hersenean plateau.
  • Earlier, this existed at a stretch from the plateau region of Spain and France to the Caucasian and Anatolian highlands. This plateau was then reduced when various factors acted on it.
  • Several faults were also formed-this finally resulting in a dissected plateau.

Question 2. Mention the names of three major rivers in Europe and their source and mouth.
Answer:

The three major rivers along with their sources and mouths are tabulated below.

WBBSE Solutions For Class 7 Geography Chapter 11 Topic A General Introduction Of The Continent Of Europe Major rivers along with source and mouth

Question 3. Describe the course of the river Danube.
Answer:

The course of the river Danube:

  • The Danube is the second longest river of Europe with a length of about 2,850 kilometres. The source of the Danube is in the Black Forest region of the German Alps.
  • The river then flows through Germany, Austria, Czech Republic, Slovakia, Hungary, Serbia, Romania and Bulgaria before discharging into the Black Sea. This river is an important international waterway and the primary international river of Europe.
  • Sava, and Drava are its main tributaries. Many important cities and towns have developed and flourished on its banks like Vienna in Austria, Budapest in Hungary and Belgrade in Serbia.

Question 4. Write about the course of the river Volga.
Answer:

The course of the river Volga:

  • The Volga is the longest river of Europe with a length of about 3,530 kilometres. The source of the Volga is in the Valdai Mountains to the northeast of Moscow in Russia.
  • After this, the river flows through the eastern part of Russia and then discharges into the Caspian Sea. Two important tributaries of the Volga are the Oca and Kama.

Question 5. Why are the north-flowing rivers of Europe are flood-prone?
Answer:

  • The rivers of Pechora, Megen, Onega, West Dvina, North Dvina and other north-flowing rivers flow from the low latitudes to the high latitudes.
  • This means that as the rivers flow from a hotter to a less hot region and during the spring the ice of the source region starts melting, but the mouth region is still frozen. This is why the north-flowing rivers of Europe are flood-prone.

Question 6. What are the special characteristics of the climate of Europe?
Answer:

The special characteristics of the climate of Europe:

Broadly speaking, the climate of the whole of Europe is mainly of temperate type. This type of climate is usually pleasant and moderate. During any time of the year, some parts or other parts of the continent experience rainfall.

The reason for this is:

  1. About 90% of Europe falls in the temperate zone and 10% falls in the frigid zone.
  2. No part of this continent is too far from the seas or oceans.
  3. The hot North Atlantic current flows along the western coastline of the continent throughout the year.
  4. Though the northeast trade winds blow over some parts of southern Europe in the summer, the westerlies blow over most areas of Europe throughout the year.
  5. The Alps Mountainous Region also influences the climate of the continent.

Question 7. What are the wind patterns that are observed over Europe?
Answer:

  • Mostly, planetary winds blow over the continent of Europe. In the northern hemisphere, in summer the pressure belts move a little to the north and so, the dry north-east trade winds blow over southern Europe and the rest of the continent experiences moisture-laden westerlies.
  • In winter, the pressure belts shift south. Because of this, westerly winds blow over the whole of Europe. However, at that time, eastern-central Europe experienced severe cold and so a high-pressure zone developed over this region.
  • As a result, the interiors of the continent do not experience much wind or breeze.

Question 8. Write a note on why Europe is supposed to be the industrially most developed in the world.
Answer:

  • Favourable environmental and economic factors are the major cause of the industrial development of Europe.
  • Several industries such as the iron and steel industry, engineering industries (motor vehicle manufacturing, aircraft construction and such others), chemical, paper, woollen textile, aluminium, electronics and others have grown in this region.
  • The most developed industrial region of Europe is Ruhr in Germany, the Donetz Basin of Ukraine, Moscow in Russia, the Paris Basin of France and the London Basin of the British Isles. This is why Europe is thought to be the industrially most developed in the world.

Question 9. Which climatic regions of Europe, do you think, are expected to be the most and least populous?
Answer:

  • In Europe, the countries with the highest population density are the Netherlands, Belgium, Germany, the British Isles, Italy and so on. These countries fall in the temperate and Mediterranean climatic zones.
  • Again, areas with low population density such as Sweden, Norway, and northern parts of Russia are part of the Tundra climatic zone and have the tundra and alpine forest zones.

Question 10. State the area of Europe.
Answer:

Area of Europe:

  • In terms of area, Europe is the sixth-largest continent in the world. Its area is only 10.9 million square kilometres. Though it is about three times the area of India, it is just 1/4 of the total land area of the continent of Asia.
  • Europe takes up about 6.8 per cent of the total land area of the Earth.

Question 3. How important is irrigation for agriculture in Egypt?
Answer:

Importance of irrigation for agriculture in Egypt:

  • The average annual rainfall in Egypt is less than 25 cm. But as the sources region of the Nile receives heavy rainfall, floods are experienced in Egypt.
  • As a result of this, the arid region of Egypt also gets covered by silt and agriculture becomes possible. Agriculture in Egypt has become one of the main sources of livelihood.
  • The major reason behind this is the fertile silt, deposited by the Nile and the irrigation facility that is available along the course of the river. As a result, high-quality cotton, wheat, banana, tobacco, millet, almond and such other crops grow here.
  • The Aswan High Dam reaps massive benefits to the Egyptian economy. The annual Nile flood could be controlled by man, for the first time in history after the Aswan Dam was built.
  • The floodwater is stored in the reservoir, with a scope to utilise it for irrigation, to increase the navigability of the Aswan Dam and to generate an enormous amount of hydel electricity. All these facilities, together lead to the development of agriculture.

Question 11. Write a note on the Aswan High Dam.
Answer:

Aswan High Dam:

Aswan High Dam is a rock-fill dam that is 111 m high and 3830 m long in Aswan, Egypt. It was constructed at the cost of 1 billion dollars in 1970.

  • Lake Nasser, the enormous reservoir, backs up the Nile about 320 km in Egypt and almost 160 km farther upstream in Sudan.
  • The Aswan High Dam reaps massive benefits for the Egyptian economy.
  • The annual Nile flood could be controlled by man, for the first time in history after the Aswan Dam was built.
  • The flood water is stored in the reservoir, with scope to utilise this for irrigation, to increase the navigability of the Aswan Dam and to generate an enormous amount of hydel electricity. It also supports fishing.

Question 12. Describe the course of the River Nile.
Answer:

The course of the River Nile:

  • Nile is the longest river of the world. The length of the River Nile is 6650 km. The White Nile and the Blue Nile join to form the River Nile.
  • White Nile rises from the Burundi Highlands, which is 50 km away from Lake Tanganyika and Lake Victoria in Tanzania.
  • On the other hand, the Blue Nile rises from the Ethiopian Highlands and meets the White Nile near Khartoum in Sudan.
  • From here the Nile flows a long way through the deserts of Egypt and near Cairo, bifurcates into 7 distributaries. Here the Nile forms its exemplary delta and falls into the Mediterranean Sea.

Question 13. Draw a chart to state the reasons for the River Nile being perennial and flooding of the Nile Basin.

Question 14. Why is the Nile a perennial river?
Answer:

  • The two major tributaries of the Nile are White Nile and the Blue Nile. The White Nile originates from Burundi Highlands and Lake Victoria.
  • This river flows through the equatorial region and thus receives a good amount of rainfall.
  • The Blue Nile originates from the Tana Lake in the highlands of Ethiopia. This river gets an adequate amount of rainfall as it flows through the region of monsoon climate.
  • As these two rivers with adequate amounts of water join together to form the River Nile. Thus it is a perennial river.

Question 16. Find out the significance of river planning on agriculture in the Nile River Basin.
Answer:

The River Nile does not cause floods all through the year and so, agriculture becomes difficult in the dry seasons.

To manage this problem, river planning has been done and dams as well as reservoirs have been constructed on the tributaries of River Nile. These dams and reservoirs are listed as follows-

  1. Aswan Dam on the River Nile, with Nasser Lake to support it.
  2. Sennar Dam on the Blue Nile.
  3. Khashm el-Girba Dam on River Atbarah.

Apart from this, some other irrigation dams have also been constructed for the convenience of agriculture.

These are-

  1. Delta Barrage,
  2. Esna Barrage,
  3. Assiut Barrage.

Countless canals and minor sub-canals have been dug on either side of the river. Water is supplied to the floodplains of the Nile and even away from it through these canals to facilitate agricultural activities.

WBBSE  Chapter 10 Continent Of Africa Topic B Nile Basin Short Question And Answers

Question 1. Why has the River Nile made the desert green in Egypt?
Answer:

  • Almost 10% of the water flowing through the continent of Africa flows through the Nile. Two of its tributaries, the Blue Nile and the White Nile have made the desert green in Egypt.
  • Dams built on the Nile have been effective enough to control flood, and water from these dams are then used for agriculture through canals.
  • Agriculture flourishes in the delta region of the Nile due to rich silt deposition.
  • Since Egypt is located in the lower course of the river, the desert region of Egypt has turned green due to the presence of the Nile.

Question 2. Describe the natural vegetation cover of the Nile River Basin.

  3. The crops of the middle course are wheat, date palm, jowar, almond, etc. The crops of lower course are olive, barley, maize, etc. The crops of the delta region are rice, wheat, cotton, etc.

Question 4. What measures can be taken to prevent the floodwater?
Answer:

  • The River Nile gets flooded every year from the month of June of September. This excess floodwater needs to be stored separately, or else the lower course of the river will be completely flooded.
  • Thus, several dams have been constructed on the course of the river. These dams hold the excess floodwater and thus help in controlling floods.
  • The water from the dams is then diverted to the dry agricultural fields to facilitate irrigation in the arid regions. Thus, in addition to flood control, agricultural activities are also enhanced.
  • At times, deep cavities are dug in the river basin to facilitate the entrance of floodwater underground and thus increase the groundwater level of the region.

Question 5. Briefly describe the permanent irrigation system of the Nile River Basin.
Answer

The permanent irrigation system of the Nile River Basin:

  • The dams, the reservoirs and the irrigation dams constructed on the course of the River Nile (Assiut Barrage, Aswan Dam, etc.) supply water for irrigation through the canals.
  • Moreover cavities have been formed to store the excess flood water.
  • During the dry seasons, when the water level falls and there is a lack of water, water is drawing out from these with the help of the Persian Wheel and Swinging Basket.
  • In this way, permanent irrigation and agriculture is made possible, not only in the floodplains but also away from them.

Question 6. Why is the Nile River Basin industrially developed?

Answer:

Topographical features of the Sahara Desert:

Physically, the Sahara Desert is part of an arid plateau region. The highest point in the desert is Mount Koussi (3415 m) in the Tibesti Mountains in Chad and the lowest is in the Qattara Depression (133 m below sea level) of Egypt.

The principal topographical features of the Sahara include the following-

1. Chotts or Shotts:

  • A chott or shott is a dry salt lake in the Saharan area of Tunisia, Algeria and Morocco that stays dry in the summer, but receives some water in the winter.
  • These lakes have changing shores and are dry for most of the year.

2. Large oasis depressions:

  • Most oases are watered by a natural spring and other underground water sources called aquifers.
  • Sometimes, a natural spring brings the underground water to the surface and at other times, manmade wells tap the aquifers. Kufra and Tuat are examples of important Saharan oases.

Question 9. Name the factors that have hindered the development of Africa.
Answer:

Though Africa is the second largest continent on Earth, yet it is not as developed as most of the other continents. The hindering factors are as follows-

Geographical hindrance:

  1. Rugged landform,
  2. Unfavorable hot desert type of climate and
  3. Infertile land

Socio-economic hindrance:

  1. Under-developed agricultural activities,
  2. Inadequate raw materials for developing industries,
  3. Lack of transportation and Untrained human resources.

Question 10. Write down topics from physiography, rivers, climate, and natural vegetation of Africa on small pieces of paper. For example, write ‘Sahara’ on a chit. Get into a group and pick up a chit each. Open it and see your topic. Now you have to talk for about two or three minutes on your topic.
Answer:

Topics such as physiography, rivers, climate, and natural vegetation of Africa have already been written on small pieces of paper. Now, the chit picked has ‘Sahara’ written on it.

Information on Sahara gathered from several books is as follows-

  • Sahara is the largest hot desert on Earth. It is bounded by the Atlas Mountains and the Mediterranean Sea to the north, the Sahel Grasslands to the south, the Red Sea to the east, and the Atlantic Ocean to the west.
  • It encompasses 11 countries of the continent. It is a plateau region composed of ancient rocks with an elevation of about 2500 m at some places.
  • The vast expanse of the Sahara is an extensive sandy and rocky terrain interspersed with thorny bushes in some places. The climate here is hot and dry with barely any water vapour in the atmosphere. In summer the temperature shoots up to 50°C or even more.
  • Al Azizia of Libya (located to the north of the Sahara) experienced a temperature of about 57.7°C in the year 1922. The vegetation found in this region is mainly cacti and date palms.
  • Crops like maize and millets are grown around the oases where there is little water availability or some favorable irrigation facility. The cultivators roam around with their animal herds, especially camels in search of food and water.
  • Camel is the main mode of transport. However, in recent times the lives and livelihoods of the people of the Sahara have seen a remarkable change. Likewise, there would be class discussions on the other topics written on various chits.

Question 11. Make a report on the advantages and disadvantages of living in the Sahara Desert. Find similarities and differences with your way of living. This report can be done on the basis of group discussion.
Answer:

Advantages of living in the Sahara Desert:

  1. Dry farming in the oases of the Sahara Desert produces maize, sorghum, millets, barley, and some vegetables. Moreover, in this desert, there are plenty of date palm trees and lots of dates are produced commercially.
  2. In the desert, due to lack of rainfall, vegetation is almost nil, some grasses and thorny bushes grow here. The Tuareg community, therefore, raises animals. When the animal fodder runs out of stock, they go elsewhere according to their nature.
  3. The recent discovery of petroleum and natural gas in Libya and Algeria, and scattered mineral salts, iron ores, and coal have been a source of alternative jobs for the people of this region.

Disadvantages of living in the Sahara Desert:

  1. Dry, soilless rocky terrain is unfit for agriculture.
  2. Occasional dust storms make people’s lives miserable.
  3. The transportation network is very poor due to harsh climatic conditions and thus the way of life is very difficult.
  4. Permanent settlements can not be built due to environmental adversity other than the ones around oases.
  5. There has been no industrial development. However, due to the recent discovery of oilfields, some oil refineries have sprung up.

Similarities and differences with our way of life:

The similarities of living in the Sahara with our way of living are-

  1. People live permanently in and around the oases and do a small amount of agriculture.
  2. The workers in the mines also live the same life as workers in our region.

The differences of living in the Sahara with our way of living are-

  1. The community living in the desert lives a nomadic life.
  2. Community ownership still prevails instead of private ownership.
  3. Reliance on camels rather than vehicles is extremely high.
  4. Lack of water, and living in a harsh environment do not match with our way of living.

The phenomenon of the rise of global average temperature is called global warming. As a result of this climatic change, the temperature of the Earth in the last century has risen by 4° Celsius. The fifth longest river of Africa. 2 29 reservoirs have been constructed on this river.

The average global temperature could rise by 1.5°C -2°C by the middle of this century. The effects of global warming can be devastating. However, in some places, its positive effects are also being noticed.

Climate change can bring out some effects on other parts of the world, apart from the Sahara Desert, such as-

  1. Due to the rapid melting of polar ice, the sea level has risen by 3mm per year in the last two decades of the last century. In the last decade of this century, a sea level rise of 5mm per year has been noticed.
  2. Many islands in the Sundarbans, including Ghoramara, Lohachara, and New Moore have submerged in the sea and many more islands could get submerged.
  3. As the sea level rises, the coastline may gradually shift more towards land area.
  4. The ocean currents are changing considerably and the global climate is changing as a result of the change in currents.
  5. Rainfall is increasing in mid-latitude countries.

Answer:

The location and extent of the Sahara Desert:

  • The Sahara Desert is located in the northern part of Africa. It extends from the coast of the Atlantic Ocean in the west to the coast of the Red Sea in the east and from the Atlas Mountains in the north to the Niger Basin and the Sahel Asine Grassland in the south.
  • The Saharan desert region extends over the countries of Algeria, Chad, Egypt, Eritrea, Libya, Mali, Mauritania, Morocco, Niger, Sudan, Tunisia and western Sahara.
  • The approximate area of the Sahara Desert is 9.2 million sq km. It is almost the same size as Europe and 2½ times of India. It is the largest hot desert in the world.

Question 2. Write about the physical characteristics of the Sahara Desert.
Answer:

The physical characteristics of the Sahara Desert are-

1. Huge physiographic extent:

  • Sahara is a huge desert consisting of extensive regions of Sandy and rocky terrain.
  • It is a plateau region consisting of vast stretches of sand and rocky fragments.

2. Narrow river channels:

  • Most of the rivers of this desert region originate from the Atlas Mountains or the Ahaggar and Tibesti Plateau Region.
  • Some rivers even disappear in the sand and the river channels of this region are extensively narrow.

3. Extreme climate:

The climate existing in this region is of an extreme type. The seasonal and diurnal range of temperatures are extreme and it hardly rains.

4. Desert vegetation:

  • Cactus types of trees are the most common in this region.
  • In certain places, oases have also developed due to wind erosion.

Question 3. Write a short note on Aerg, Reg and Hamada.
Answer:

Aerg, Reg and Hamada:

  • Aerg is a large accumulation of sand deposited by the wind in the form of a small hill in the Sahara Desert.
  • The regions of the desert where sand and rock fragments are found together are called Reg. Hamada is the rocky part of the desert with no sand.

Question 4. Write a brief note on Wadi.
Answer:

Wadi:

  • The Sahara Desert being a dry region does not see many rivers. Only the Nile flows through the east and Niger flows through the south-western part of the Sahara.
  • During the rains, sometimes small rivers emerge, that dry up very soon in the arid climate.
  • This dry non-perennial river in the east of the Sahara Desert or a valley or streambed in northern Africa that remains dry except in the rainy season is known as Wadi.
  • Wadi Draa is an ideal example of the dry river of the Sahara.

Question 5. Discuss the important climatic characteristics of the Sahara Desert region.
Answer:

Important climatic characteristics of the Sahara Desert region:

Sahara is the hottest and driest desert in the world. The important climatic characteristics of this region are as follows-

  1. Tremendously hot days and extremely cold nights.
  2. Summer temperatures that sometimes shoot up to 58°C during the day and come down to 4°C during the night.
  3. Rainfall of about 15 cm in certain places and no rainfall at all in some other places.
  4. The overall climate of the Sahara is hot and dry and stays around the extreme type.
  5. Sometimes hot sandstorms are noticed in this regions-these are known as Simoom in the local language. Khamsin in Egypt and Harmattan near the Gulf of Guinea is a warm-dry wind that blows from Sahara in summer.

Understanding the Sahara Desert

Question 6. Why is a desert as big as Sahara, formed in the tropical region of Africa?
Answer:

The reason why the Sahara Desert has formed in the tropical region of Africa are as follows-

1. North-east trade winds:

  • The northeast trade winds blow in the northern part of the Sahara.
  • This is a dry wind blowing from Eurasia.
  • Since the water vapour content in the wind is nil, thus it does not cause any rainfall.

2. South-east trade winds:

  • The southeast trade winds blow over waterbodies before entering Africa and thus cause rainfall in the south-eastern coast of Africa after being struck by the mountains along that coast.
  • Thereafter, the winds are devoid of any rainfall while blowing northwards in the continent towards Sahara.
  • As a combined influence of these two dry winds, the Sahara has formed as a desert region in spite of being in the tropics.

Question 7. Give a brief account of agriculture in the Sahara Desert Region.
Answer:

Agriculture in the Sahara Desert Region:

  • Scarce availability of water and infertile soil with an abundance of sand poses an eternal problem for cultivation in the Sahara Desert region.
  • So, agricultural activities are quite limited in this region.
  • Agricultural activity can only be noticed in the oasis regions of the Sahara Desert.
  • In these regions, some minimal agricultural activities are noticed that too with the help of well and canal irrigation. Crops like maize, dates and millet are grown here.

Question 8. Name some important cities of the Sahara Desert.
Answer:

Some important cities of the Sahara Desert are as follows-

Question 9. Give a brief account of transportation facilities in the Sahara Desert Region.
Answer:

Transportation facilities in the Sahara Desert Region:

  • The transportation facilities of the Sahara Desert Region is underdeveloped and still very primitive. The major form of transportation of the Sahara Desert Region is on the backs of camels.
  • This is why the camel is also known as the ‘Ship of the desert’.
  • Camel is the only mode to travel between the oases of the Sahara Desert. In the recent past, due to the development of oil refineries, motor vehicles have started plying in some places, like in the Niger Basin in Algeria and the Chad Basin.
  • Some of the crucial airports of the Sahara Desert Region are Dakhla, Hassan-I, Smara (Semara), Kano and others.

Question 10. What would have happened if the Sahara Desert was located in the south of Africa?
Answer:

The Sahara Desert is located in the northern part of tropical Africa. If the desert was located south of Africa, the following would have happened.

  • Climate change: A temperate climate instead of a tropical climate would have prevailed. The coastal areas along the Indian Ocean in southern Africa would have been very cold.
  • Change of vegetation: Temperate grassland instead of desert plants could have been seen.
  • Season change: The opposite seasons would have prevailed instead of the present ones.
  • Changes in the natural and cultural environment: Almost opposite characteristics of the present natural and cultural environment of the Sahara Desert would have prevailed.

Question 11. Why are settlements almost absent in the Sahara Desert?
Answer:

Settlements are not found in the Sahara Desert because-

1. Sandy terrain:

Sandy terrain of the Desert makes the land unfit for the growth of the settlement.

2. Extreme climate:

  • The climate of this region is extremely dry and the diurnal range of temperature is also extreme.
  • The temperature shoots up to 58°C during the day and falls down to 4°C at night.
  • There is hardly any evidence of rainfall. Thus, the climate is highly unsuitable for the growth of settlement.

3. Infertile soil:

The soil of this region is infertile and its salt content is very high. Thus, it cannot support agriculture on a proper basis and as a result, settlement does not flourish in and around this region.

Question 12. What are the advantages and disadvantages of global warming in the Sahara Desert Region?
Answer:

The advantages and the disadvantages of global warming in the Sahara Desert are-

1. Advantages of global warming: The consequence of rainfall as a result of global warming has led to an increase in agricultural activities, animal rearing and an increase in the species diversity of the region.

2. Disadvantages of global warming: The evidence of fossils found on the rocks of this region explains the presence of greenery once upon a time. However, the region has gradually turned dry and arid due to climate change.

Question 13. Name the rivers of the Sahara.
Answer:

Rivers of the Sahara:

  • Nile River flows through the eastern Sahara and rivers like Niger, Chari, and Logon flow through the southwestern Sahara.
  • The Sahara region does not see an abundance of rivers because it is dry and rainless. Even the rivers that flow, mostly remain dry, except the Nile. Wadi Draa is a dry river of the Sahara.

Question 14. Why is Sahara sparsely populated?
Answer:

  • The Sahara Desert is sparsely populated because temperatures constantly touch 55°C during the day and drop very low at night, so it is difficult for people to live there. The average rainfall is very low.
  • There is no fertile soil cover and so, agriculture cannot be done. Due to limited water supply, it is difficult to sustain livelihoods and lives.
  • Its isolated location, poor communication systems, restricted accommodation and few job opportunities are additional factors for a sparse population.

Question 15. How does an oasis form?
Answer:

  • Most oases are watered by natural springs and other underground water sources. Underground water sources called aquifers supply water to most of the oases.
  • Sometimes, a natural spring brings the underground water to the surface and at other times, manmade wells tap the aquifer. Kufra and Siua are examples of important Sahara oases.

Khamsin:

A kind of hot local wind in the Sahara Desert is known as Khamsin. This wind blows with extreme heat and dryness in summer. The heat of this wind kills people and cattle.

Question 17. Describe the natural vegetation of the Sahara Desert.
Answer:

Natural vegetation of the Sahara Desert:

  • Sahara Desert is thinly covered by an ambit of natural vegetation that ranges from grasses to hardy shrubs to trees with long root systems, which are saline tolerant.
  • The natural vegetation of the Sahara is adapted to the heat and highly unreliable precipitation.
  • Many of the Saharan areas see the growth of thorny bushes and cacti, which are naturally adapted to the retention of moisture within their body.
  • In the oasis regions palm family of trees like dates can be seen.

Question 18. Write about the mineral deposits of the Sahara Region.
Answer:

The mineral deposits of the Sahara Region:

  • The existence of extreme weather conditions makes it very difficult for mineral extraction in the Sahara Region.
  • Yet, reserves of petroleum and natural gas have been found in Libya and Algeria. Salt, coal and iron ore are also found.
  • Developed transport networks and airports have been built in recent times for the development of mining and easy transportation of the extracted minerals.
  • The nomadic animal herders have now started working in the local oil and gas mines.

Question 19. Write about the industrial growth in the Sahara Desert Region.
Answer:

The industrial growth in the Sahara Desert Region:

  • Harsh environment, inadequate raw material for heavy industries, lack of infrastructure, insufficiency of power supply and inadequate investments are some of the reasons for which the Sahara Desert Region has not witnessed much industrialisation.
  • The only kind of industry that is found in the region are oil refineries, wool and cotton weaving mills, sugar mills and some small-scale handicrafts.

Question 20. Was Sahara always under the influence of the hot desert-type climate?
Answer:

  • Sahara was not always under the influence of the hot desert-type climate. Very recently the fossils of aquatic plants and animals found on the rocks in the Sahara clearly prove this fact.
  • So, it can be supposed that once Sahara was under the influence of a wet rainy climate

Answer:

  • Lake Turkana (6405 sq. km), formerly known as Rudolf Lake, is the fourth-largest lake among the East African lakes. It is the world’s largest permanent desert lake.
  • The major portion of the lake lies in Kenya, while the northern part stretches into Ethiopia. The lake is a rich reservoir of fish.

Question 24. Briefly describe Drakensberg’s Mountain.
Answer:

Drakensberg’s Mountain:

  • The African meaning of the word Drakensberg Mountain, the main mountain of South Africa, is ‘Dragon Mountain’.
  • Running parallel to the coast of South Africa, Drakensberg Mountain rises to more than 3475 m and stretches from northeast to south- west for about 1125 km. Thabana Ntlenyana is the highest point of Drakensberg Mountain.
  • Rock and cave art can be noticed in this range. Apart from this, several game reserves and parks are also present here.
  • The Ukhahlamba Drakensberg Park was designated as a UNESCO World Heritage Site in the year 2000.

Important Definitions Related to the Sahara Desert

Question 25. Name the ocean currents that flow parallel to the coastline of Africa.
Answer:

The ocean currents that flow parallel to the coastline of Africa originate from the Atlantic Ocean in the western side and from the Indian Ocean in the eastern side.

The ocean currents from the Atlantic Ocean are-

  1. The Canary Current flows along the African coast from north to south between 30°N and 10°N
  2. The Guinea Current flows to the east along the Guinea coast of West Africa.
  3. Benguela Current flows northward along the west coast of southern Africa nearly to the Equator.

The ocean currents from the Indian Ocean are-

  1. Somalian Current flows along the coast of Somalia and Oman in the Western Indian Ocean.
  2. The East Madagascar Current flows near Madagascar.
  3. The Mozambique Current flows south along the African east coast in the Mozambique Channel, between Mozambique and the island of Madagascar.

Question 26. Why have the deserts of Africa formed near the tropical and the sub-tropical regions?
Answer:

  • Most of the northern part of Africa is covered by the Sahara, the world’s largest desert, and in the southern hemisphere lies the Kalahari Desert.
  • Both of these are located in the tropical and the sub-tropical regions and as a result lie under the influence of the trade winds.
  • These trade winds originate from the sub-tropical high-pressure zone and move towards the equatorial low-pressure zone.
  • As they move from the relatively cooler zone to the hotter zone, the moisture-carrying capacity of the trade winds becomes very high.
  • So, we observe very little cloud formation and subsequent rainfall near the sub-tropical regions. This leads to the formation of these enormous deserts.

Question 27. Briefly describe the temporary irrigation system of the Nile River Basin.
Answer:

  • In the lower Nile Basin, natural levees and floodplains have formed on either side of the river banks. These floodplains are very narrow, extending only about 20 km.
  • During the summer, as the Blue Nile encounters heavy monsoon rainfall in the Ethiopian Highlands, the lower course of the River Nile floods. The floodwater is allowed to flow to the lower floodplains by opening the sluice gate.
  • This helps the soil to rejuvenate with newly accumulated silt and thereafter a large amount of crops can be grown. In this way, starting from Aswan till the delta region of the Nile River, irrigation becomes possible.
  • But this operation is only possible during the time of flood, and so, it is described as the temporary irrigation system of the Nile River Basin.

Question 28. Give a brief account of animal rearing in Africa.
Answer:

Animal rearing in Africa:

There are quite a number of places in Africa that are known for their animal rearing. They are as follows-

  1. In South Africa, there is a large stretch of temperate grassland or Veld in its plateau region. This grassland is mostly used for sheep rearing.
  2. To the north, east, and south of the equatorial rainforest region, lies the large expansion of tropical grassland or Savanna. Livestock like cattle and pigs is reared here in the countries of Sudan, Angola, Nigeria, Uganda, Kenya, Zimbabwe, and such others.
