Question:
How come I always see meteorite craters with no
meteorites in them? How big was the meteorite that formed the Barringer
crater in Arizona?
Replies:
Most meteors vaporize in the energetic collision with the ground. Parts of
what are left end up buried beneath the surface. A crater is typically 16
times larger than the meteor that created it.
