What is a desert?

Desert Biome is found on every continent. A desert is an area that receives rainfall of 10 inches or less a year.
Deserts can be very hot or very cold.
For example, the Sahara desert is the largest hot desert, and the Gobi desert in China is very large and cold most of the year.
Animals and plants in the desert must have adaptations that allow them to survive on little water.
