Question

Quizplus · Accepted Answer

The tropics receive the greatest annual input and least seasonal variation in solar radiation due to their location near the equator where the angle of incidence of the sun's rays is perpendicular to the surface year-round. The polar regions, on the other hand, have the least annual input and most seasonal variation in solar radiation due to their location near the poles where the angle of incidence is low and varies greatly throughout the year. The temperate zones have an intermediate level of annual input and seasonal variation.
