WBBSE Solutions For Class 6 Geography Chapter 11 Maps Topic A Accurate Representation Of The Earth

Chapter 11 Maps Chapter Synopsis

 

1. A map is a diagrammatic representation of the entire Earth’s surface or parts of it, showing the geographical distribution of physical or man-made features on a specific scale.

2. A physical map is an illustration of the physical features like mountains, rivers, forests, etc of the Earth.

3. A political map is the representation of administrative boundaries of countries, states, cities, districts, etc.

4. A map specifically drawn to represent a particular theme (such as weather, population, transport and communication), related to a specific geographic area is known as a thematic map.

5. A globe is a sphere-like small model of the Earth which also helps us to understand how the Earth spins on its axis. The location of any country, continent and waterbody can be very easily spotted on a globe.

6. An Atlas is a collection of maps in the form of a book. In the 16 century, geographer G. Mercator published the first book on maps and named it Atlas’ after the Greek God Atlas.

7. The art and science of map-making are known as Cartography.

8. A map that has two dimensions i.e. length and breadth and is also known as a two-dimensional map. For example, a world map on plain paper is a two-dimensional map.

9. A three-dimensional map has three dimensions i.e., length, breadth and height. It has volume also. For example, globe.

10. A scale of a map is the specific ratio, in which the actual part of the Earth is reduced and shown on a map.

11. Maps which depict a vast area of the world are known as small-scale maps. For example, Atlas, wall map, globe and some topographical maps.

12. Maps which are drawn to depict a small area are known as large scale maps. For example, mouza map, town map, etc.

13. The conventional signs and symbols used in a map are shown in a small box in any one corner of the map. This is known as the index or legend or key.

14. A plan is drawn to precisely depict a small area like a house, a room, etc. It is a type of large scale map.

15. All maps of the world use some standardised colours, signs, symbols and letters to denote universal meanings. These are called conventional signs and symbols.

Question 1. Why are a globe and a map essential components for learning geography?
Answer:

A globe and a map essential components for learning geography:

The reasons why a globe is an essential component for learning geography are as follows—

Occurrence of day and night:

The occurrence of day and night on Earth can be explained better with the help of a globe.

Concept of the Earth’s axis:

The Earth’s axis is tilted at an angle of 661/2° to the orbital plane of the Earth. This concept can be easily understood with the help of a globe.

The reasons why maps are an essential component of learning geography are as follows—

Concept of a region:

The role of maps is most important for gaining a clear idea about a region.

Knowledge about geographical aspects:

We depend on maps in order to collect information like topography, rivers, climate, transportation, population, agriculture, industry, trade, etc of a region.

Determination of direction:

Maps are required to get an idea about the cardinal directions.

Question 1. Discuss the different types of maps.
Answer:

Different types of maps:

Maps can be primarily divided into three categories.

They are as follows—

Physical maps:

Maps depicting several physical features like mountains, plains, plateaus, deserts, rivers, and natural vegetation are called physical maps.

Political maps:

Maps showing countries and states with their boundaries are called political maps.

Thematic maps:

Maps that show specific information on specific themes such as population, roadways, railways, minerals, etc. are called thematic maps.

Question 2. How is the location of any place on the globe determined?
Answer:

The location of any place on the globe determined:

The location of any place on the globe is determined by the help of parallels of latitude and meridians of longitudes.

The point of intersection between parallels and meridians is the exact location of any place.

The imaginary, circular lines running across the surface of the globe in an east-west direction are called lines of latitude. They are parallel to the Equator and to each other.

The semicircular, imaginary lines running from the North Pole to the South Pole and intersecting the Equator at right angles are called lines of longitude.

They are equal in length but hot parallel to each other. The intersection of these imaginary lines of latitude and longitude, known as the geographic grid, allows us to give a mathematical value to the location of any place on the globe.

Question 3. Write a brief note on cartography.
Answer:

Cartography:

The science and art of making maps is known as cartography. It involves the representation of political, cultural, economic and other attributes in a specific geographic area.

The technology used for cartography has been continuously changing. The first maps were hand-painted and lacked accuracy.

The advent of the compass and eventually computers have made maps more accurate and useful.

Question 4. What is the usefulness of a map?
Answer:

Usefulness of a map:

A map is an essential tool that helps us to study geography.

It is used to determine the locations of rivers, mountains and landforms in various cities, countries or continents. Maps influence all our lives.

For example, the location and extension of land boundaries, roadways, rivers, ponds, settlements, and religious establishments can be determined from a cadastral map.

The distance of a particular settlement from the roadways or railways, the nature of a settlement or a forest can also be determined by using a map.

Question 6. Which is considered to be the most recent era of map making?
Answer:

The most recent era of map making:

From cave paintings to ancient maps of Babylon, Greece and Asia, till the 21 century, people have developed and used maps for various purposes.

In the 15 century, maps were drawn on wooden or copper planks. Maps became increasingly accurate and factual during the 17,18 and 19 centuries with the application of scientific methods.

This is known as the modern era of maps. The world was poorly known until the widespread use of aerial photography following World War-1 Modern cartography is based on a combination of ground observations and remote sensing.

Question 6. Write a short note on the cadastral map.
Answer:

Cadastral map:

Cadastral maps show individual landed property or land registration, that is, the record of ownership of land.

One key feature of a cadastral map is that it carries detailed information about a particular location.

It is an official map that is generally not available for sale. A usual cadastral map in India bears a scale of 16 inches = 1 mile.
