◉ 1. Rotation and Revolution. Answer: The moon and Earth revolve and
rotate. Rotation is when a planet or moon turns all the way around or
spins on its axis one time.
The axis of rotation is an imaginary line going from the north pole to the
south pole.
When a planet or moon travels once around an object this is considered a
revolution.
On Earth, a rotation is pretty short - it happens once a day! It is the
rotation that makes the sun appear to come up in the morning and set at
night. On Earth, a revolution is quite a bit longer - one year!
The moon is a little different. The moon rotates once about every 27-29
days, and revolves once about every 27-29 days. So every time the moon
goes around Earth it turns around one time. That is why the moon
always looks the same - we only ever see one side of it!
