Quizplus · Accepted Answer

The rain shadow effect is caused when warm, moist air ascends a mountain and releases the moisture as rain or snow near the top. As the air mass descends the other side of the mountain, it is dry and does not release any more moisture, creating a "shadow" of dryness and little precipitation. This is why areas on the leeward side (downwind) of mountains are often much drier than those on the windward side (upwind). Option A is incorrect because dry air does not form rain clouds. Option B is incorrect because warm air with moisture would typically produce rain or snow on the windward side, not after it has descended the mountain. Option D is incorrect because warm air with no moisture would not produce rain or snow.
