A fault-block mountain forms where the edges of two plates come together to create a fault. When one plate pushes up over the other one, the upper one can continue up until it is high enough to ...
[/caption] Fault-block mountains are formed by the movement of large crustal blocks when forces in the Earth’s crust pull it apart. Some parts of the Earth are pushed upward and others collapse ...
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.
Some examples of fault-block mountains include the Sierra Nevada and the Grand Tetons in the United States and the Harz Mountains in Germany. Fault-block mountains are formed as a result of cracking or faulting along the planet's surface, leading to several crustal blocks being heaved upwards while other chunks of rocks slide downwards.
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 Mountains or ranges that result from the upthrow of large fault blocks and that are separated from others by basins or troughs, producing an upland unit bounded by normal or reversed faults.

The Sierra Nevada Mountains of the Western United States are an example of fault-block mountains. This mountain range formed between 130 and 400 million years ago as the Pacific Plate lowered underneath the North American Plate, a process known as subduction. There are three major types of mountains including the fault-block variety.
Mountains in West Virginia. Both complex mountains and erosional mountains are present in West Virginia. The Allegheny Front and the St. Clair Fault form a dividing line between the two types (Figure 11). The complex mountains are located along and east of the Allegheny Front and the St. Clair Fault.
