What geological feature is created when two blocks of rock move toward each other under compression?

The geological feature created when two blocks of rock move toward each other under compression is a reverse fault. This type of fault occurs in response to compressive stress, where one block of rock, known as the hanging wall, moves upward relative to the other block, called the footwall. The movement and deformation of rocks in this manner help to accommodate the forces generated by tectonic plate interactions, often occurring at convergent plate boundaries.

Reverse faults are characterized by steeply dipping fault planes and are significant because they can lead to the development of mountain ranges as tectonic forces push the Earth's crust upward. Understanding reverse faults is crucial for comprehending geological processes such as the formation of some of the Earth's most prominent topographical features.
