when a colliding boundary collides and pushes up a mountain. an example of a fault block mtn. range is the Himalayas.
Actually the previous answer is incorrect. They form when the tenison pu on Earth is so great that it caused large blocks of rock to move down relative to the other causing a change in elevation and a moutain to form. The previous answer was how folded mountains form....

RafaFault-block landforms (mountains, hills, ridges, etc.) are formed when large areas of bedrock are widely broken up by faults creating large vertical displacements of continental crust.
Vertical motion of the resulting blocks, sometimes accompanied by tilting, can then lead to high escarpments. These mountains are formed by the Earth's crust being stretched and extended by tensional forces. Fault block mountains commonly accompany rifting, another indicator of tensional tectonic forces.
The uplifted blocks are called block mountains or Hosts. The intervening dropped blocks are termed grab en: these can be small or form extensive rift valley systems. This form of landscape can be seen in East Africa, the Vosges, the Basin and Range province of Western North America, in south-central New England, and the Rhine valley. These areas often occur when the regional stress is extensional and the crust is thinned.
Fault block mountains form when tectonic forces cause large blocks of the Earth's crust to move vertically, resulting in one side of the block being uplifted while the other side drops down along a fault line. Over time, erosion can further shape and expose these blocks, creating mountain ranges with steep slopes and flat mountain tops.

What kind of mountains form from vertical fault movement?
Fault-block mountains form from vertical fault movement. These mountains are created when blocks of the Earth's crust are pushed up and down along fault lines, resulting in steep, jagged peaks and valleys. An example of a fault-block mountain range is the Sierra Nevada in California.
What happens to the lithosphere as fault-block mountains form?
As fault-block mountains form, the lithosphere is stretched and pulled apart along fault lines. This stretching causes the crust to fracture and blocks of rock to move vertically, creating a series of alternating valleys and ridges. Over time, the fault-block mountains continue to uplift and erode, shaping the landscape.
How do folded volcanic and fault block mountains differ?
Folded mountains form when tectonic plates push against each other, causing the Earth's crust to buckle and fold. Fault block mountains, on the other hand, result from the displacement of large blocks of crust along fault lines. Fault block mountains tend to have steep cliffs on one side and a more gently sloping side known as a "fault scarp."

Which type of fault cause a fault-block mountain to form?
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.
