Question

the prevailing winds in the region shown below blow over the sea, then up and over a coastal mountain. which geographic area best represents the rain shadow? choose 1 answer: ⅰ ⅱ ⅲ ⅳ

Explanation:

A rain - shadow is a dry area on the leeward (downwind) side of a mountain. When prevailing winds blow over the sea, they pick up moisture. As the air rises up the windward side of the mountain (II), it cools and condenses, causing precipitation. By the time the air reaches the leeward side (IV), most of the moisture has been lost. Area IV is on the leeward side of the mountain, so it is the rain - shadow area. Area I is over the sea, area II is the windward side (where precipitation occurs), and area III is just part of the mountain's upper region but not the leeward dry area.

Answer:

D. IV
