C)Mixing ratio
D)Air temperature
E)Air pressure

Question

Quizplus · Accepted Answer

As a parcel of air rises, it expands and cools due to the decrease in atmospheric pressure with altitude. The cooler temperature causes the air's capacity to hold water vapor (saturation vapor pressure) to decrease, but the actual amount of water vapor in the air (mixing ratio) remains constant unless water vapor is added or removed. Since relative humidity is the ratio of the actual vapor pressure to the saturation vapor pressure, and the saturation vapor pressure decreases more rapidly than the actual vapor pressure as the air cools, the relative humidity of the rising air parcel increases.
