Answer:
Shock or impact metamorphism
Step-by-step explanation:
There are different types of metamorphism. These are:
- Contact metamorphism
- Regional metamorphism
- Impact or contact metamorphism.
Impact or shock metamorphism results from concentrated and targetted pressure on a particular rock. It is usually from the collision of a bollide with the surface of the earth. The resulting impact quickly alters the rock metamorphically thereby deforming it and causing the minerals to rearrange in a new way.
