The revolution of the moon around the earth makes the moon appear as if it is changing shape. From Earth we see the moon grow from a thin crescent to a full moon, and then shrink back to a thin crescent again. The phases of the Moon depend on its position in relation to the sun and Earth. As the moon makes its way around the Earth, we see the bright parts of its surface at different angles. These are called "phases" of the moon.
