In and Around the Crater
The compressed rocks rebound immediately, causing an explosion
that blasts out huge quantities of material. Much of this
debris falls back to Earth around and in the crater.
The shock wave pulverizes surrounding rock, and the incredible
pressure creates distinctive new minerals.
In a hypervelocity collision, the heat is so intense that
it completely melts rocks at and near the point of impact.
That molten rock turns solid again and becomes glass.
