When oceanic and continental plates collide, one plate is forced under the other.  What term describes the places where these plates overlap?

What is a subduction zone?

500

What is the difference between fault block mountains and thrust faulting mountains?

Thrust faulting: When the rock is squeezed from the sides, it can form into slabs that move up and over like shingles on a roof.

Fault Block: They are formed when tectonic forces stretch Earth’s crust, fault blocks can tilt or slide down. The older rock may end up on top of the younger rock.
