Rain Tends to Be Much More Common in Mountains Than

Multiple Choice

Rain tends to be much more common in mountains than in the adjacent lowlands because

A) as air travels up the mountains, it cools. Cool air holds less moisture than warm air, and the excess moisture is dropped as rain.
B) as air travels up the mountains, it is compressed. The mountains squeeze the water out of the air, which is dropped as rain.
C) because of their great height, mountains are often in the clouds. Precipitation is much greater in these clouds.
D) as air moves down the mountains, it expands and is unable to form clouds, so no rainfall occurs.
E) the rainfall is equal in both mountains and lowlands; however, because the rain has farther to travel from the clouds to the lowlands, more of it evaporates before it reaches the ground in the lowlands.
