Question 1. Describe the northern fluvial plains on the Northern Plains.
Answer:

The northern fluvial plains on the Northern Plains:

The northern fluvial plains lie between the Himalayas in the north and the Peninsular Plateau in the south.

The major rivers that flow through this area are the Ganga, Yamuna, Ghagra, Gandak, Kosi, Son, Chambal and others.

The eroded materials brought down from the mountains by these rivers and form this fluvial plain region.

This makes the plain area suitable for agricultural activities.

The Northern Plains can be further sub-divided into 3 distinct divisions. They are as follows—

1. The Punjab Plain,
2. The Ganga Plain,
3. The Brahmaputra Plain.

1. The Punjab Plain: This plain area has developed from the alluvial deposits brought down by the rivers Jhelum, Chenab, Ravi, Beas, Sutlej.

2. The Ganga Plain: This floodplain mainly extends through the states of Uttar Pradesh, Bihar and West Bengal. This fertile plain has formed by the rich alluvium deposits brought down by the river Ganga and its tributaries.

The Brahmaputra Plain: This is the floodplain developed due to the river deposits brought down by the river Brahmaputra.

The Majuli Island in the middle of the Brahmaputra’s course, is the world’s largest river island.

Characteristics: The Northern Plains have the following characteristics—

1. The average elevation of the plains are under 300 m.
2. The transport network over the plains is very well developed due to the favourable topography.
3. The favourable agricultural condition and developed transport network make these plains suitable for human settlement.

Question 2. Briefly describe the northern mountainous region.
Answer:

The northern mountainous region:

Northern mountainous region is located at the extreme north of India. It is extended from Jammu and Kashmir (previous) to Arunachal Pradesh.

Himalaya and Karakoram are the main mountains in this region. Godwin Austin (8611 m) of Karakoram is the highest peak in India and the second highest peak of the world.

But the Himalayan mountain range is the main mountain range in India.

A description of the Himalayan mountainous range is tabulated below—

 

 

Question 3. Discuss the reasons for the increase of population in the mountainous regions. Or, Can you tell the reason behind the recent increasing trend of settlements in the mountainous area?
Answer:

The reasons for the increase in the density of population in the mountainous regions

Are as follow—

1. Increase in population: The increasing rate of population in India forces people to form settlements in the mountainous regions also.

2. Increase in tourism: With the growth of tourism, there has been greater economic development in the hilly regions.

More hotels and other tourism amenities are developing which results In an increase in the density of the population in these regions.

3. Availability of transportation facilities: Development in transportation facilities also has an impact on the population density of a region.

As conveyances increase, it becomes easier to live and work in these areas even for non-natives.

4. Better standard of living: With the increase in job opportunities even in the hilly regions, the people here have more disposable income to spend on a better lifestyle even in the difficult living conditions of the hills.

Even basic amenities like electricity, which was not available earlier, is now available in most places.

5. Industrialisation: The increase in the opportunities for the development of the industries like handicrafts, publishing houses, and fruit-processing industries have made opportunities for living and working in the hills more lucrative.

Question 7. Give an idea of India from physiographical the picture below. Suggest your opinion regarding the influence of this physiography on human life.

Answer: The picture is of the Western Deserts of India, located in the western part of Rajasthan, known as Thar.

Physiographical Characteristics: The desert area is dry, sandy and almost without vegetation. Scanty rainfall for a long time has turned the desert devoid of agricultural practices.

Few nonperennial rivers are seen here. These rivers are unable to empty into seas. Most of the desert is comprised of large sand dunes.

Influence on human life: The Thart desert is a sparsely populated area. The main occupation of the people is dry farming and animal husbandry. The local people live as nomads.

Camels play an important role in the transportation of this area. The unique physiographic characteristics of this region attract numerous domestic and international tourists every year.

The physical constraints make human life difficult to sustain daily needs.

Question 8. Suppose you have visited Shimla, Goa, and Rajasthan. Write about these places.
Answer:

Shimla, Goa, and Rajasthan are three famous tourist spots in India. I have visited these places and I have some basic information about these places are—

Shimla: Shimla is the capital of Himachal Pradesh and is situated amidst the Himalayas.

Description: We reached Shimla from Kalka by toy train.

Since Shimla is located in the Himalayan foothills, at night it was quite cold. It receives snowfall in winter. We could see a great distance far and wide from the Mall in Shimla.

The roads there were all sloping and winding. The mountainsides were forested with tall, straight pine trees.

Rajasthan: Rajasthan is a land of desert that is located in Western India.

Description: The western part of Rajasthan seems to be an ocean of sand. There are hillocks of sand known as sand dunes. The days are extremely hot but the nights are very cold.

This region thus experiences extreme climate. There are very few trees in this region and crops are not cultivated here.

Camels are the most common animals here they are called ‘ships of the desert’. That deserts can be so beautiful, that I understood only after visiting Rajasthan.

Goa: Goa is a small state on the western coast of India.

Description: Goa is neither very hot nor very cold since it is on the coast of the Arabian Sea.

We enjoyed a moderate temperature throughout. The sea looks beautiful from the beaches of Goa.

The coast has lots of coconut and palm trees. We all played football on the beach. Goan food is also very different and delicious.

Question 4 Discuss the influence of the Northern Mountains on lives in India.
Answer:

Northern Mountains on lives in India:

The Northern Mountains greatly influence life in India in the following ways-

To the extreme north of India lies the Himalayan Mountains which act as a wall by protecting the country in winter from the cold winds of central Asia.

Many snow-fed rivers originate from the glaciers of the Himalayas and the alluvial deposits laid down by these rivers have formed the North-Indian riverine plains.

The natural beauty of this region attracts many tourists every year, creating economic opportunities for the local population.

Question 5. Why is the population density in the Himalayan region comparatively low?
Answer:

The population density in the Himalayan region is comparatively low because-

1. Extreme coldness: The temperature is not suitable for life due to extreme cold in this region.
2. Difficulty in agriculture: The slope of the land in the Himalayan region is very steep, and the soil is rocky and very difficult to cultivate.
3. Underdeveloped transportation system: Due to the uneven terrain of the region, the transportation system is underdeveloped. For all these reasons, the population of the Himalayan region is relatively low.

Question 6. Describe the North-Indian riverine plain or the Northern Plains.
Answer:

The North-Indian riverine plain or the Northern Plains:

The North-Indian riverine plains or the Northern Plains are situated between the Himalayas in the north and the Peninsular Plateau in the south.

The Northern Plains cover the states of West Bengal, Bihar, Assam, Uttar Pradesh, Haryana, and Punjab.

The Ganga, Brahmaputra, and Indus are the main rivers flowing through these plains. The average elevation of these plains is 300 m above sea level.

These plains were formed by the alluvial deposits laid down by the rivers and they are highly fertile and suitable for cultivation.

Regionally the plains can be divided into Punjab Plain, Ganga Plain, and Brahmaputra Plain.

 

 

Question 7 Write a short note on the river Ganga.
Answer:

River Ganga:

The river Ganga is the longest and largest river in India. The left bank tributaries of river Ganga are Gomti, Gandak, Kosi, and others.

The right bank tributaries of the river Ganga are Yamuna, Son, and others. Dehradun, Haridwar, Kanpur, Allahabad, Varanasi, Patna, and Kolkata are some of the important cities on the bank of the river Ganga.

Source and mouth: The river Ganga originates from Gomukh in the Gangotri glacier located in Uttarakhand and it discharges into the Bay of Bengal. The total length of this river is about 2500 km.

Course: Ganga is an ideal river in India because it is a long river and all the courses of this river can be seen clearly.

The upper course: From the source in Uttarakhand till Haridwar, is the upper course of the river Ganga. Near the source, it is known as the river Bhagirathi. Later on, Bhagirathi meets the river Alaknanda to form the river, Ganga.

The middle course: The stretch between Haridwar and Rajmahal Hills in Jharkhand is the middle course of river Ganga.

 

 

The lower course: From the Rajmahal Hills to the Bay of Bengal is the lower course of the river Ganga.

Near Dhulian in the Murshidabad district of West Bengal, the Ganga divides itself into two distributaries.

The main branch flows into Bangladesh as river Padma, which later on discharges into the Bay of Bengal as river Meghna.

The other branch flows as Bhagirathi-Hooghly through West Bengal and discharges into the Bay of Bengal.

Question 8. Write a short note on the river Brahmaputra.
Answer:

Brahmaputra:

Brahmaputra is the second-longest river in India. The right bank tributaries of river Brahmaputra are Manas, Sankosh and others.

The left-bank tributaries of the river Brahmaputra are Buri-Dihang, Dhansiri and others. Dibrugarh, Tezpur, and Guwahati are some of the important cities on the banks of the river Brahmaputra.

Brahmaputra Majuli island is the world’s largest river island.

Source: The river Brahmaputra originates from the Chemayangdang Glacier near Manas Sarovar in Tibet. In Tibet, this river is known as Tsangpo.

The lower course: From the Rajmahal Hills to the Bay of Bengal is the lower course of the river Ganga. Near Dhulian in the Murshidabad district of West Bengal, the Ganga divides itself into two distributaries.

The main branch flows into Bangladesh as river Padma, which later on discharges into the Bay of Bengal as river Meghna.

The other branch flows as Bhagirathi-Hooghly through West Bengal and discharges into the Bay of Bengal.

 

 

Course: Brahmaputra is a large river system. But only 916 km of its entire length (2900km) flows through India.

After flowing through Tibet, the river enters India from Arunachal Pradesh turning southwest near Namcha Barwa Peak.

Thereafter, the river flows towards the west through Assam. The Brahmaputra is the united flow of Dibang, Dihang, and Lohit which continues till Dhubri in Assam and finally enters Bangladesh.

In Bangladesh, the river is known as Jamuna. River Jamuna, later on, meets Padma, the distributary of River Ganga. River Jamuna and river Padma together flow into the Bay of Bengal as the river Meghna.

Question 9. Write a short note on the river Indus.
Answer:

River Indus:

The river Indus (length 2880 km) is the main river of north-eastern India. It originates from the Sengge Khabab Glacier in the Kailash

 

 

Mountains near Manas Sarovar. It flows through Jammu and Kashmir and Himachal Pradesh and turns south near Nanga Parbat to enter Pakistan.

The united flow of this river and its tributaries finally merge into the Arabian Sea. The Jhelum (Bitasta), Chenab (Chandrabhaga), Beas (Bipasha), Ravi (Iravati), and Sutlej (Satadru) are the main tributaries of this river.

Question 10 Write a short note on Bhabar.
Answer:

Bhabar:

The region lying to the north of the Ganga plains is known as the Bhabar region. It is situated at the foothills of the Himalayas.

The soil of this region consists of sand and pebbles and is porous in character. The porosity is so high that all the streams flow underground.

This region has been formed mainly by the deposition of rocks, pebbles and sand brought down by the rivers originating in the Himalayas.

Question 11 Why is India called a ‘land of rivers’?
Answer:

India called a ‘land of rivers’;

Many rivers crisscross the Indian subcontinent creating a vast riverine network.

These rivers play a very important role in the lives of the people of India, such as in agriculture, industry, hydroelectricity, transport, trade and commerce and so on. Thus, India is called a ‘land of rivers’.

Question 13. Discuss the influence of the Northern Riverine Plains on life in India. Or, Why is the Northern Plains so densely populated?
Answer:

The North-Indian Riverine Plains influence greatly life in India in the following ways-

1. Agriculture: These riverine plains apart from the desert region in the west provide fertile land for cultivation. Crops like paddy, wheat, sugarcane, jute, cotton, and pulses are cultivated here.

2. Industry: Many industries have been set up here because of the developed transport network, supply of local raw materials, and low-cost labour.

3. Settlement: The flat land surfaces, favorable climatic conditions, economic opportunities, well-developed transport system, etc.

have helped to form major cities in this region. The main cities of this region are Kolkata, Patna, Chandigarh, Delhi, Agra, Allahabad, Varanasi, etc.

Question 14 Discuss the peninsula plateau region.
Answer:

The peninsula plateau region:

To the south of the Northern Plains, lies the Peninsular Plateau region of India. Many plateaus of Madhya Pradesh, Maharashtra, Karnataka, Kerala, and Tamil Nadu, etc are parts of this region.

This region is made up of Thus, it is a pre-Cambrian shield region. The elevation of the entire region decreases from west to east with the average elevation being 600m-900m and the southern part of the region is comparatively higher than the northern part.

The region is bounded by the Aravalli Hills, the Satpuras, and the Vindhyas to its north, Nilgiris, Anaimalai, and Palni to the south, Western Ghats to its west and Eastern Ghats to its east.

The large step-like igneous rock formation in the northwestern part of this region is known as the Deccan Trap.

Question 15. Write a short note on the Deccan Trap.
Answer:

Deccan Trap:

The north-western part of the Peninsular Plateau region is known as the Deccan Trap or Lava Plateau. ‘Deccan’ means south and ‘Trap’ means stairs or step-like features.

The elevation of this region decreases from west to east. The lava flowing onto the surface over a thousand of years has formed this region.

Question 16. Discuss the influence of the Peninsular Plateau region on life in India.
Answer:

The influence of the Peninsular Plateau region on life in India:

The Peninsular Plateau region has a great influence on life in India in the following ways-

The different parts of the Peninsular Plateau region are rich in various minerals such as iron ore, coal, limestone, copper, manganese, etc.

Crops like cotton, paddy, nut, onion, sugarcane, orange, and grape are also cultivated in this plateau region.

The availability of agricultural raw materials and minerals has also helped to set up many industries.

The rivers flowing through this region are a source of water for irrigation and for hydel power generation. Many parts of this plateau region are also rich in forest resources.

The favorable climatic condition of the plateau region makes it suitable for human settlement. These settlements then become sources of cheap labor for the nearby industries.

Question 17. Write a short note on the Western Ghats.
Answer:

Western Ghats:

The Western Ghats are a mountain range that runs almost parallel to the western coast of the Indian peninsula.

It starts near the border of Gujarat and Maharashtra and runs through the states of Maharashtra, Goa, Karnataka, Tamil Nadu, and Kerala, ending at Kanyakumari.

The Sahyadri, Nilgiri, and Annamalai are some of the well-known mountains and hills of the Western Ghats.

AnaiMudi (2695 m) is the highest peak in this region. Many national parks, sanctuaries, and protected forests are situated here.

Question 18. Write a short note on the Eastern Ghats.
Answer:

Eastern Ghats:

The Eastern Ghats are a discontinuous mountain range extending over the coastline of eastern India.

The range stretches from Odisha in the north to Tamil Nadu in the south. Godavari, Mahanadi, Krishna, and Kaveri are the main rivers eroding and cutting through this region.

The Deccan Plateau lies to the west of this range. Jindhagada Peak is the highest peak of the Eastern Ghats. Though these ghats are not as high as their western counterparts.

Question 19. The rivers Narmada and Tapti do not form any delta at their mouths.
Answer:

The rivers Narmada and Tapti originate from the Amarkantak and the Multai regions respectively.

These rivers flow through the rift valley of the Deccan Plateau and finally drain into the Arabian Sea. Deltas are formed when rivers lay down alluvial deposits on plain lands.

But this particular region plane has a steep slope. The rivers flowing through this plateau area are very fast-moving, with less erosive action.

Hence, not many eroded materials are deposited by these rivers during their courses of 1312 km and 724 km respectively.

These rivers also have a lesser number of tributaries. Also, the steep slope of the mouth region at the Gulf of Khambat does not allow the formation of a delta.

It is because of the combined effect of all these reasons that the Narmada and the Tapti do not form deltas at their mouths.

Question 20. Write a short note on the Thar Desert. Or, Write a short note on The Great Indian Desert.
Answer:

Thar Desert:

In the western part of Rajasthan, lies the Great Indian Desert known as the Thar.

The climate here is dry and arid with little or no rainfall. Very little vegetation grows here apart from some xerophytes. Due to the scarcity of water, there is hardly any agriculture.

Date palm trees are grown in oases in the desert region. Very few and tiny ephemeral streams can be seen here at times.

Question 21. What are the reasons for the formation of deserts in India?
Answer:

The reasons for the formation of deserts in India are as follows:

1. Alignment of the Aravalli Mountains: Due to the north-south alignment of the Aravalli Mountains, the Arabian Sea branch of the south-west monsoon winds blows parallelly past the Aravalli Mountains and thus does not shed moisture in the western part of India.

2. Dry southwest monsoon wind: The Bay of Bengal branch of the southwest monsoon sheds all its moisture in the northeastern, eastern, and northern parts of India.

Thus, by the time it reaches the western part, the winds become totally dry and cause no rain there.

Question 22. Why is the population density so low in the desert region of India?
Answer:

The population density is very low in the desert region of India, because-

1. Lack of drinking water: Due to low rainfall and lack of rivers, drinking water is not abundantly available in the desert region.

2. Difficulty in agriculture: Agriculture is very difficult here due to the lack of rainfall and water.

3. Lack of factories: Due to the lack of a favorable environment, no industries have been developed here.

4. Lack of basic services: Due to underdevelopment in transportation and other infrastructure, basic amenities for people are not available here. For these reasons, very few people live in desert areas of India.

Question 23. Describe the coastal plains of India.
Answer:

The coastal plains of India:

The region lying between the coastline of India on either side and the Peninsular Plateau region is known as the coastal plain.

This plain extends from the Gulf of Kuchchh in the west to the Ganga-Brahmaputra delta in the east along the coastline.

The Western Coastal Plain lies between the Western Ghats and the Arabian Sea in the west while the Eastern Coastal Plain lies between the Bay of Bengal and the Eastern Ghats in the east.

The presence of many small and large ports in the coastal region has contributed greatly to trade and commerce. The alluvial deposits of these plains are one of the major sources of petroleum.

Fishing is an important economic activity of the people of this region. Arabian Sea to the southwest.

Deposition of the skeletal remains of tiny marine animals called polyps has formed these islands. The deposition of these polyps together forms corals.

Question 24. Give a brief description of the island region of India.
Answer:

Island region of India:

An island is a landmass surrounded by water on all sides. Many islands together form an island group. Two large island groups lie to the southeast and southwest of India.

A total of 256 small and large islands make the Andaman and Nicobar Island group in the Bay of Bengal to the southeast, while 25 such islands form the Lakshwadeep Island group in the Arabian Sea to the southwest.

Deposition of the skeletal remains of tiny marine animals called polyps has formed these islands. The deposition of these polyps together forms corals.

 

 

Question 25. Write a short note on Coral islands.
Answer:

Coral islands:

Tropical islands formed from the calcium animals called corals are referred to as coral carbonate-rich skeleton deposits of tiny marine islands.

Coral islands form in the shallow water of clear oceans where sunlight can easily reach. When corals die, the remains of their bodies are deposited upon one another.

This grows in height, eventually forming an island. The Lakshadweep Islands in the Arabian Sea are coral islands.
