Block mountains represent the upstanding parts of the ground between two faults or on either side of a rift valley or a graben. Types of Block Mountains: Essentially, block mountains are formed due to faulting in the ground surface. Block mountains are generally of two basic types e.g.:
Fold Mountains. Fold mountains are formed when sedimentary rock strata in geosynclines are subjected to compressive forces.; Formation of Fold Mountains was explained previously in Continent – Ocean Convergence – Formation of Andes, Rockies And Continent – Continent Convergence: Formation of Himalayas. They are the loftiest mountains and they are generally concentrated along continental ...
How Are Fault-Block Mountains Formed? Fault-block mountains form when Earth's crust pushes material up and down near a fault line. Rocks that get pushed upward eventually form mountains if there is enough seismic activity. The higher part of a fault-block area is called a horst, while the lower part is called a graben, according to Ducksters. ...
Fault Block Mountains. Fault block mountains are distinguished by great sheer rock faces. These form when enormous underground pressure forces a whole rock mass to break away from another. The line at which this break takes place is called a fault. On one side of this break the rocks rise; on the other side they sink down.

Fault-block mountains often result from rifting, another indicator of tensional tectonic forces. These can be small or form extensive rift valley systems, such as the East African Rift zone. Death Valley in California is a smaller example. There are two types of block mountains; lifted and sloped.
The Fault-block Mountains or block mountains are created when faults or cracks in the Earth's crust force materials or blocks of rocks upward or down. The uplifted blocks are Block Mountains or horsts. The intervening dropped blocks are called graben, which can be small or form rift valley systems. These block mountains break up into chunks or ...
Mountain formation refers to the geological processes that underlie the formation of mountains. These processes are associated with large-scale movements of the Earth's crust (tectonic plates). Folding, faulting, volcanic activity, igneous intrusion and metamorphism can all be parts of the orogenic process of mountain building.
Block Mountains. Block Mountains or fault-block mountains arise as a result of faults in the crust. The faults enable rocks to move past one another, a process known as rifting. Rocks on one side rise higher in comparison to the others, and they form Block Mountains (horsts) while the other blocks of rocks drop to form depressed regions (graben).
