INTRODUCTION: A map is a representation of a part or whole of the Earth’s surface drawn according to a scale on a plain sheet of paper, cloth or wood. It gives an overall, bird’s eye view of an area. Globes are a true representation of the spherical Earth in the form of a model. But if you look at a globe, you will see that you cannot view the entire Earth at a time until you rotate the globe.

This is not so with maps. On a map you can view the Earth entirely at a glance. So maps were devised to study the Earth and to learn about the various features present on the surface of the Earth.

3. Which of the following is an intermediate direction?

Answer: (c) North-West

4. A map showing the distribution of industries is a :

Answer: The topographical maps bear the national grid of squares drawn to the scale of 2 cm = 1 km, with each square having a side measuring 1 km. With reference to any of these sheets, the vertical lines are called Eastings since they are numbered from West to East. Similarly, the horizontal lines are called Northings because they are numbered from South to North. The network of horizontal and vertical lines, or the Eastings and Northings in a map, is called Grid Reference.

6. Briefly explain the three components of a map.

Answer: Three components of maps are direction, distance (scale) and symbols.

i. Direction: Direction is the most important component of a map. It is important and useful to describe where one place is in relation to another.
