Generalized global air circulation and precipitation patterns are dependent on the intensity of solar radiation near the equator.Which of the following correctly states an event that contributes to the creation of these global patterns?
A)rising,warm,moist air masses at 30 degrees north and south
B)rising air masses that expand and cool in the tropical regions
C)rising cool,moist air masses at 90 degrees north and south
D)rising air masses that expand and warm in temperate regions

Quizplus · Accepted Answer

As the sun's rays are most intense near the equator, they heat the air and cause rising air masses to expand and cool in the tropical regions. This creates low-pressure zones that lead to the formation of zones of circulating air that drive the global air circulation and precipitation patterns. Therefore, choice B is the correct answer, as it describes the event that contributes to the creation of these patterns. Choices A, C, and D do not describe events that contribute to the creation of global air circulation and precipitation patterns.
