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.
Fold mountains form when two tectonic plates move together (a convergent plate boundary). Fold mountains form from sedimentary rocks that accumulate along the margins of continents.When plates and the continents riding on them collide, the accumulated layers of rock may crumple and fold like a tablecloth that is pushed across a table, particularly if there is a mechanically weak layer such as salt.he forces responsible for formation of fold mountains are called orogenic movements. The term orogenic has derived from a Greek word meaning mountain building. These forces act at tangent to the surface of the earth and are primarily a result of plate tectonics.
