Question 12 • Earth and Space Science

If a mountain ridge forces moist air upward, what can you infer about where cloud formation will most likely occur?

Answer
A
At the mountain base, where the air is warmest and driest.
B
At the summit, but only if the relative humidity is below 50 percent .
C
On the windward slope, as rising air cools and reaches saturation.
D
On the leeward slope, as descending air warms and dries.

Explanation

Moist air forced up a mountain cools as it rises. When it cools enough to reach saturation, water vapor condenses into clouds, so cloud formation is most likely on the windward slope. Descending air on the leeward side warms and becomes drier, making clouds less likely there.
