2. MAPS

C.        Answer the following questions.

1.     A globe is the most accurate way to represent the Earth. However, we generally use a map rather than a globe to study the Earth. Why is this?

Ans. The map gives more detailed information of a place than a globe. It is not possible to see all the parts of the Earth at the same time on the globe and moreover, it is difficult to carry a globe. Maps give detailed information of each  place on the Earth. Maps can be drawn to any size. There are maps that show different features of the same place.

2.     A map of the earth will have errors in the shape and size of places shown on the map. Why is that so?

Ans. The shape of the Earth cannot be flattened out accurately on paper. So, there are some errors in the shapes and sizes of the land masses which the people who make the maps try to minimise.

3.     How is direction usually shown in maps?

Ans. Maps usually show north at the top, south at the bottom, east to the right and west to the left.

4.     What do you understand by the term ‘scale of a map’?

Ans.  A map does not show the actual distance between places. Distances are shrunk so that the area being mapped can be fitted on a piece of paper. To be able to do this accurately, maps are drawn to a scale. The scale of a map is the ratio between distance shown on the map and the actual distance on the ground.

 

 

5.     Which standard colours are used in maps?

Ans. Certain standard colours are used in maps to show features such as oceans, seas, mountains, plains, deserts, etc.

• Water bodies are always shown in blue. Deep blue shows deep waters and light blue shows shallow waters.

• Mountains and highlands are shown in brown and yellow. Dark brown shows high mountains. Light brown shows lower mountains and hills. Yellow shows plateaus.

• Plains and lowlands are shown in green.

6.     What are symbols?

Ans. Symbols are shapes or signs, which show certain features and places on a map.
