A desert is a very dry biome. They get less than 25 cm (about 10 inches) of rainfall a year. Another source defines it as "any region that can have a moisture deficit over the course of a year. In other words, they can have less rainfall in a year than they give up through evaporation".

These kinds of areas can cover about 33% of the land on Earth. That includes much of Antarctica, where large areas get no snow at all. The largest hot desert is the Sahara desert, in northern Africa, covering 9 million square kilometers.

Deserts land surfaces are various – examples are stones, sand dunes and snow. They have a wide variety of animals and plants. Deserts sometimes expand (desertification), and sometimes contract.

Deserts are mostly found in the western part of the Americas, Western Asia, Central Australia, and South and North Africa. Many, such as the Sahara (the largest), are very hot during the day and have cold nights, but there are also cold deserts such as the Atacama in South America which remain frozen day and night.
