Latitudinal variation in sunlight intensity - ANSWER-Earth's curved shape causes latitude variation in the intensity of sunlight. Because sunlight strikes the tropics ( those regions that lie between 23.5 N and 23.5 S) most directly, more heat and light per unit of surface area are delivered there. At higher latitudes, sunlight strikes Earth at an oblique angle, and thus the light energy is more diffused on the Earth's surface. Global air circulations and precipitation patterns - ANSWER-Intense solar radiation near the equator initiates a global pattern of air circulation and precipitation. High temperatures in the tropics evaporate water from earth's surface and cause warm, wet
