Why Does the Moon Change Shape?

Answer

The moon keeps changing its shape because the position of the moon and the sun's reflection on it keeps changing. The moon orbits around the earth every 29 and a half days and during this revolution we see the light reflected from the sun at different angles and in different shapes. This is what forms the phases of the moon.

The Moon dose not change shape, it only appears to change shape. What you are seeing is the shadow of the Earth falling across the surface of the Moon. Because the Moon is a ball in space the shadow looks curved on its surface giving the Moon a crescent shaped appearance.
