desert is an area of land with little precipitation. Consequently, living conditions are hostile for plants and animals, which need special adaptations to survive in this hard environment.

Deserts are formed because of large variations in temperature between day and night, which break rocks in pieces.

Deserts take up about one third of the land surface of the world. This includes much of the polar regions where occurs little precipitation and which are sometimes called "cold deserts".
