text: why does the moon always show us the same face,?   because it has a real slow rotation around the earth (1 rotation per revolution) as opposed to the earth around the sun (365 rotations per revolution)   it looks like its not rotating, but it is.  take something round like an orange or something, make an x on it.  try to make it go around you while still showing the x...you'll see that you'll need to rotate it slowly as you move it around you
