Metamorphism occurs because some minerals are stable only under certain conditions of pressure and temperature. When pressure and temperature change, chemical reactions occur to cause the minerals in the rock to change to an assemblage that is stable at the new pressure and temperature conditions.
        
             
        
        
        
Answer:

Explanation:
We use the kinematics equation to solve this question:

 because the ball is dropped
    because the ball is dropped
 the acceleration is the gravity, negative because it points downwards
         the acceleration is the gravity, negative because it points downwards
 initial height
     initial height
 final height
     final height
So:


 
        
             
        
        
        
Answer:
compression 
Explanation:
compression can produce faulting in rocks in the form of thrust faults and can also cause liner valleys (grabens) and mountains
