16: When air masses meet, why does warm air rise over cooler air, often causing rain? A. Warm air is less dense than cooler air. B. Warm air is denser than cooler air. C. Cooling air can hold less water vapor than warmer air. D. Cooler air is very volatile |
C. Cooling air can hold less water vapor than warmer air.

The motion of the warmer air over cooler air is due to differing densities, but it is the drop in temperature due to increased elevation and contact with cooler air (among other things) that causes the rain. As air cools, its capacity to hold water vapor decreases. As the saturation point is reached, excess water vapor condenses on particles in the air and eventually can fall as rain |
