### Globes and Maps

• A model of Earth, called a globe, shows us the whole Earth. We can rotate it see different places. However, a globe is not big enough to show all the places in detail.
• To solve this problem we have drawing of a part of the Earth or the whole of it. Such drawings are called maps.
• A map can be big or small. We can hang a big map on a wall. It's called wall map.
• A book of small maps is called an atlas.

### Directions on a Map
