How do deserts form in the rain shadow of mountains?

Quick Answer

Mountains force moist air upward, causing rain on the windward side and dry conditions on the leeward side.

The Full Story

When moist air hits a mountain range, it rises, cools and releases precipitation on the windward slope. After crossing the peak, the air descends, warms and becomes drier, creating a rain shadow on the other side. This process can produce much lower rainfall in nearby regions and even help create deserts. Examples include the dry eastern side of the Andes in parts of South America and the region east of the Sierra Nevada in the United States.
