Question

Why do we see different phases of the Moon

Answer 1

During the lunar month, the Moon goes through all its phases. You can see the phases drawn in the image below. Just like the Earth, half of the Moon is lit by the Sun while the other half is in darkness. The phases we see result from the angle the Moon makes with the Sun as viewed from Earth.

hope this helps :)

Answer 2

Because the moon gets its light from the sun so therefore when the moon spins round and the earths shadow blocks certain parts of the moon, we see different views of it.
