Answer:
1.Oblate spheroid
The shape of the moon is that of an oblate spheroid, meaning it has the shape of a ball that is slightly flattened.
2.The Moon appears to change shape because we see different amounts of the lit part as the Moon orbits Earth. When the Moon is between Earth and the Sun, the lit side is hidden from us. As it moves around Earth, more and more of the lit side comes into view. ... It takes 29.5 days for the Moon to orbit Earth
3.The Moon gradually looks a little different each day, depending on where it is in its orbit. The Moon's lunar cycle begins when the Sun, the Moon, and Earth are aligned (the Moon is between Earth and the Sun) and the illuminated hemisphere of the Moon faces away from Earth.
4.-9.As the Moon orbits our planet, its varying position means that the Sun lights up different regions, creating the illusion that the Moon is changing shape over time. The best way of getting to understand the lunar phases is to regularly go out on a clear night when the Moon is in the sky and observe it.
10.The Moon doesn't emit (give off) light itself, the 'moonlight' we see is actually the Sun's light reflected off the lunar surface. So, as the Moon orbits the Earth, the Sun lights up different parts of it, making it seem as if the Moon is changing shape.
