What is a desert?
Deserts are places which receive very little rainfall for long periods of time. This makes the area very dry and therefore hard to live in, but some animals and plants find ways to survive in these harsh conditions. Deserts can be hot, warm, cool or cold places. The polar regions, the Arctic and Antarctic, are cold deserts. A quarter of the world is desert; more if you include cold deserts.
