How does the elastic-rebound theory explain the occurrence of earthquakes?
choose one:
a. colliding rocks cause kinetic energy to travel through the crust in the form of earthquakes.
b. the bending motion of crustal rocks causes the surrounding crust to vibrate as earthquakes.
c. when bending rocks fail, stress energy is released in the form of earthquakes.
d. when bending rocks fail, tension energy is released in the form of earthquakes.

C.  

Explanation:

the elastic-rebound theory explain the occurrence of earthquakes When bending rocks fail, stress energy is released in the form of earthquakes.

elastic-rebound theory in geology is the study of how energy is released during an Earthquake, The crust rapture along the fault line; the sudden movement releases the accumulated energy , the rock snap back almost to their original shape.

Hence option C is correct

because there are alot of mountains
