text: what happens to what caused the craters? we see the craters on earth and on the moon but... what happens to the actual asteroids and meteors that created them? where did they go and why don't we see them? i would expect to see a big rock embedded. most of them get vaporized and/or broken up on impact.  just think of a bomb... you can't find the remains of it after the explosion.  also, comets make craters but are made of mainly ice, so they have no remains.
