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 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.
