How is a plateau different from a fault-block mountain?

A plateau is defined as a highland area that has a flat top topography, which has steep sides. These are often formed when the intrusive magma crystallizes before it comes out to the surface. The flat top surface of the plateaus are formed due to the continuous erosion process that has taken place since the geological time.

On the other hand, a fault-block mountain is a type of mountain which are formed due to the reverse faulting. It results from the upward movement of the blocks. These are jagged mountains and are formed from the compressional stress.

Thus, the plateaus are formed from the erosion process, and fault-block mountains are formed due to the compressional stress.

Plateau results from erosive processes whereas faultblock mountains are the result of orogenic faulting, usually the result of compression.
