Why do clouds form near the summit on the windward side but not on the leeward side?

As air is forced up the windward slope, it expands and cools. When it cools to its dew point, water vapor condenses into cloud droplets, forming clouds near the summit. On the leeward side, air descends and warms, so clouds are less likely to form. The correct choice is C, “Rising air cools to the dew point on the windward side.”
