Question

which describes how prevailing winds affect precipitation in a region? prevailing winds force cool, moist air from oceans to rise. prevailing winds blow in the opposite direction as normal winds. prevailing winds cause huge air masses, both warm and cool, to move. prevailing winds that move over land usually cause the most precipitation.

Explanation:

• The first option is incorrect because prevailing winds carry warm, moist ocean air, not cool, which rises and condenses into precipitation.
• The second option is incorrect as prevailing winds are the dominant, normal wind direction for a region, not opposite.
• The third option is correct: prevailing winds drive the movement of large warm and cool air masses, which interact to create precipitation patterns.
• The fourth option is incorrect because winds over land lose moisture, so they cause less precipitation than winds from oceans.

Answer:

Prevailing winds cause huge air masses, both warm and cool, to move.
