Question

which option identifies the two natural wind patterns that move air masses in the united states?
○ prevailing westerlies and jet streams
○ polar easterlies and jet streams
○ trade winds and prevailing westerlies
○ trade winds and polar easterlies

Explanation:

To determine the correct answer, we analyze the wind patterns affecting the US. Prevailing westerlies (mid - latitude winds) and jet streams (high - altitude wind currents) are the key wind patterns that move air masses in the US. Polar easterlies are more relevant to polar regions, and trade winds are in tropical regions, so they don't primarily affect air mass movement in the US.

Answer:

A. prevailing westerlies and jet streams
