What Causes Earth To Receive Slanted And Direct Rays?

The hemisphere that is more directly facing the Sun at a given point in Earth’s orbit receives more of the Sun’s energy. When the Sun is directly over your head, you are receiving the Sun’s most direct rays. But your shadow is shortest because it falls directly underneath you. As the tilt of the Earth changes relative to the Sun, the seasons change. On the winter solstice the angle of the Sun is lowest on the horizon, shining at you more than on you. This is why it casts a longer shadow in winter.
