Q

Why does the moon change shape?

A

Our Moon’s shape doesn’t really change — it only appears that way. The “amount” of Moon that we see depends on what phase the moon is in as it rotates. As our Moon orbits around Earth, the side facing the Sun is always illuminated, just like Earth’s daylight side is illuminated by the Sun.
