Fault-Block Mountains: 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 blocks and move either up or down. When they move apart blocks of rock get stacked on one another Fault-block Mountains usually have a steep front side and then a sloping back side.
The uplifted part forms a mountain, and the lowered parts are filled in with eroded material. An example of this is the Sierra Nevada mountain range in California. Another way that mountains are formed is when magma from beneath the Earthâs surface is pushed up, but doesnât actually crack through.This bulge of magma eventually cools and hardens into hard rock, like granite. The layers of softer rock above the magma erode away and youâre left with a large dome-shaped mountain.he mountain ranges are created because of those crumpling plates. The Indian subcontinent âcrashedâ into Asia 25 million years ago and created the Himalayan mountain range. In fact, the Himalayans are still growing! The next way that mountains are formed is along fault lines.
