How much rain does a desert usually get?
Most experts agree that a desert is an area of land that receives no more than 25 centimeters (10 inches) of precipitation a year. The amount of evaporation in a desert often greatly exceeds the annual rainfall. In all deserts, there is little water available for plants and other organisms.
Why is rain so rare in the desert?
Why It Doesn’t Rain Much in the Sonoran Desert Since cool air cannot retain as much water vapor as warmer air can, the excess water precipitates. Moisture blowing in from the ocean is effectively drained, and the air that moves down the ranges’ eastern slopes is usually so dry it cannot produce any more rain.
Why do deserts receive less rainfall?
Some deserts are near the equator where the air is very dry. Some deserts are in the middle of a continent. By the time the wind gets there, it has little moisture. If rain falls it stays dry in deserts because the sand absorbs the water.
