All about Deserts
A desert is a dry region that receives very little rain, generally less than 25 cm a year. Many deserts are hot, like the Sahara, but some are cold, like Antarctica, which is the largest desert on Earth.
Desert plants and animals have adapted to survive with little water. Cacti store water in their stems, camels can go a long time without drinking, and many desert animals are active at night when it is cooler.

The Sahara in North Africa is the largest hot desert in the world.
Why is Antarctica a desert?
Deserts are defined by how little precipitation they receive, not by heat. Antarctica receives very little snow, so it is classed as a desert.
