Why does the moon have phases?
Answer 1:

The moon has phases because moonlight comes from the Sun. Sunlight shines on one side of the moon, and the other side of the moon is dark. When the moon moves around the earth, we sometimes see the light side of the moon. At other times, we see only the dark side of the moon, or we see part of the light side and part of the dark side of the moon.

Here is a website that explains the moon phases.
