Question

Which accurately describes one way that coastal mountains affect a region’s 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.

Answer 1

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

When air is pushed up the windward side of coastal mountains it cools, water vapor condenses and falls as precipitation (orographic rainfall), often leaving drier air on the leeward side.
