A desert is dry because it receives little precipitation. A desert is described as a region that receives less than 10 inches (250 mm) of rainfall per year on average. Deserts are a natural occurrence caused by geography. Mountains can prevent atmospheric moisture from entering a region causing a rain shadow desert to form.
