    Think about how craters (or holes) appear anywhere on earth. There needs to be an impact from on object. Think larger, fast moving objects in space.

    The Moon has craters because it has been struck by meteorites (I think that is the correct term?).

    When they were in space the meteorites had lots of KE, which was converted into thermal, kinetic, and elastic potential on the Moon's surface. Thermal as it would have had friction with the surface, kinetic as debris would have been ejected in all directions, and elastic potential as then Moon's surface will be compressed.
    You may also talk about the gain in KE before the meteorite strikes as it loses GPE by nearing the Moon.
