MapsA globe is a three-dimensional

representation of the earth. It provides a way to view the earth as it travels through space.

But since the earth is round, we can see only one-half of it at any time.

As a result, for some tasks, globes are not very practical because they are not portable.

MapsPeople prefer to use maps, which are two-dimensional graphic representations of

selected parts of the earth’s surface.

The advantage of maps is that they are portable.

The disadvantage of maps is that distortions occur in flattening the earth’s surface to create the map.
