Question

which accurately describes one way that coastal mountains affect a regions climate? they determine the way that large masses of cool, dry air move over land. they control the amount of water vapor present in cool, dry air masses. they decrease precipitation on the windward sides of mountain ranges. they force cool, moist air from oceans to rise as it moves toward land.

Explanation:

Coastal mountains act as barriers. When cool, moist ocean - air moves towards land, the mountains force this air to rise. As air rises, it cools and condenses, leading to precipitation on the windward side. This is the orographic effect. The other options are incorrect as they misstate the role of coastal mountains in air - mass movement and precipitation.

Answer:

They force cool, moist air from oceans to rise as it moves toward land.
