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.

Explanation:

When prevailing winds carry moist air from the ocean towards a mountain range, as the air rises up the up - wind side of the mountains, it cools. As it cools, water vapor in the air condenses to form droplets of liquid water, which eventually leads to precipitation. This is why the up - wind side gets more precipitation. On the down - wind side, the air has already lost much of its moisture.

Answer:

B. Water vapor condenses to form droplets of liquid water.
