In mountainous regions, which side typically receives more precipitation?

In mountainous regions, which side typically receives more precipitation?

• A. The windward side
• B. The leeward side
• C. The south side
• D. The top of the mountains

Answer: (A)

Moist air moving with prevailing winds is forced to rise as it meets mountains. While it rises, the air cools and the moisture condenses into clouds, so rain or snow falls on the windward side. Once the air crosses the peak, it descends, warms, and dries out, creating a rain shadow on the leeward side. The top of the mountain isn’t inherently wetter than the windward slope; the key pattern is that the windward side receives most of the precipitation due to the lifting and cooling of the moist air.
