Types of Maps
Maps are of several types. They are mainly classified into:
Physical or Relief Maps: These show natural features of the earth.Political Maps: These maps show the cities, town and villages, countries and states of the world with their boundaries.Thematic Maps: These maps focus on specific information like the map of a rainfall, roads, tourist places.Components of Maps
Maps have three components: distance, direction, and symbol. We measure distance in terms of scale. A scale is a ratio between the actual distance on the ground and the distance shown on the map.
To measure large areas like continents or countries on a paper, we use a small scale map.To show a small area like your village to town on a paper, we use a large scale map.
Directions are cardinal points like North, South, East and West. And symbols are certain letters, shades, colours, pictures and lines, which give us information about a limited place. Various other things like sketches and plans are used to draw an area of a large scale.
Globe Versus A Map

However, maps, are a representation on a piece of paper, does not spin.Globes are made of hard materials and cannot be folded making them difficult to be carried around. However, you can easily fold and carry maps all along with you.You can use a map for navigating from one place to another. However, globes don’t provide enough specific details to help you in navigation.
