ENERGY AND THE EARTH’S SHAPE : Because the Earth is in the shape of a sphere, there will be parts of the Earth that receive direct energy from the sun and other regions of the world that receive indirect energy. Notice the Earth’s axis in this drawing. The axis is the imaginary line about which the Earth spins. It is straight up and down. If this is how the Earth went around the sun each year, the seasons would always remain the same.
