Question

the diagram shows that the upwind side of a mountain range tends to receive more precipitation than the downwind side of a mountain range. which statement is most useful for explaining this observation? a. prevailing winds flow from west to east. b. water vapor condenses to form droplets of liquid water. c. evaporation allows water vapor to rise through the air. d. cold air holds less moisture than warm air.

Explanation:

When prevailing winds carry moist air towards a mountain range, the air rises. As it rises, it cools. Cold air holds less moisture than warm air (d). So, the water vapor in the air condenses to form droplets of liquid water (b), which leads to precipitation on the up - wind side. Evaporation (c) is part of the water cycle but doesn't directly explain the difference between up - wind and down - wind precipitation. The direction of prevailing winds from west to east (a) is not relevant to this specific mountain - related precipitation difference. The key concept here is the relationship between air temperature and moisture - holding capacity.

Answer:

d. Cold air holds less moisture than warm air.
