<P> Figure 3 shows the angle of sunlight striking the earth in the Northern and Southern hemispheres when the Earth's northern axis is tilted away from the Sun, when it is winter in the north and summer in the south . </P> <P> Heat energy is not received from the Sun . Rather, radiant energy is received and this results in change in energy level of receiving bodies in Earth's domain . Different materials have different properties for transmitting back received energy in the form of heat energy at different rates . </P>

What effect does this have on the heating at different latitudes of the earth
