A Block Mountain.
A Block Mountain.
A fault-block mountain is formed when higher blocks of land are displaced along a fault line, causing one side of the fault to rise relative to the other. This creates a steep-sided mountain range with a distinctive block-like structure.
Fault block mountains are formed when large blocks of the Earth's crust are uplifted along faults. Tensional forces cause the blocks to move vertically relative to each other, creating steep mountain ranges and valleys. As the blocks continue to move, the mountains can be further uplifted and shaped by erosion.
A normal fault causes a fault-block mountain to form. In a normal fault, one block of rock moves downward relative to the other, creating a step-like feature. Over time, repeated movements along the fault can uplift and deform the crust, leading to the formation of fault-block mountains.
A fault-block mountain is characterized by steep, rugged slopes on one side and a more gradual slope on the other. They are formed when tectonic forces cause a block of rock to be uplifted along a fault line, creating a mountain range with distinct asymmetric features. Examples include the Sierra Nevada in California and the Teton Range in Wyoming.
This is called a strike slip fault.
Where fault blocks collide into each other. The most prominent example of this are the Himalayan Mountains formed by the collision of the Indian plate and the Eurasian Plate making what is called a folded mountain.
The answer is a dip-slip fault, When a portion of rock moves upward leaving the other in place with a dip this is known as a dip-slip fault.

The type of fault that occurs when the hanging wall moves up relative to the footwall is called a reverse fault. This movement is typically associated with compressional forces in the Earth's crust, often resulting from tectonic plate convergence. Reverse faults can also lead to the formation of mountain ranges and other geological features. A specific subtype of reverse fault is known as a thrust fault, where the angle of the fault plane is relatively low.
