Question

Quizplus · Accepted Answer

At about 30 degrees north and south of the equator, warm air rises and moves towards the poles. This leaves behind a region of low pressure where cool air from higher latitudes moves in to replace the rising warm air. As this cool air moves towards the equator, it gets warmed, which reduces its relative humidity and ability to hold moisture, resulting in dry conditions. Additionally, the descending air creates a stable atmospheric condition, which resists the formation of clouds and precipitation. Therefore, option B is the best choice as it explains the process of cool air falling, getting warmed, and absorbing moisture, leading to dry conditions.
