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.
One other way mountains form is as the result of volcanic activity below Earthâs surface. Sometimes molten rock called magma gets pushed up toward the surface. When that happens, it cools and forms hard rock.Eventually, the softer rock above it erodes to reveal a dome-shaped mountain below.ne other way mountains form is as the result of volcanic activity below Earthâs surface.
