It heats the earth UNEVELY. MORE heat energy is absorbed closer to the EQUATER making it WARMER. LESS heat is absorbed at the NORTH and SOUTH Poles making it COOLER.Convection occurs in OCEAN currents, GLOBAL winds and MANTEL of the earth.00Convection CurrentsSUN is the MAIN source of heat energy on earth.
