Why do the tropics get more energy per unit area from the sun than do the higher latitudes (say, 50° north or south) even when both get 12 hours of sunlight per day? View Available Hint(s)for Part A The stratospheric ozone layer is thicker away from the equator, so less heat energy can reach the surface.Because the Earth curves away from the sun, the sun is farther away at higher latitudes.The Hadley Cells cause more cloud formation at higher latitudes blocking the sun.The curve of the Earth's surface means that the same amount of sunlight is spread over a larger area at higher latitudes.
