Block Mountains are formed by the internal earth movements.
When the forces of tension act on the rocks, they create faults in them.
When the land between the two almost parallel faults is raised above the adjoining areas, it forms a block mountain.
It may also occur when land on the outer side of the faults slips down leaving a raised block between them.
The rocks composing the fault levels may be flat-lying or even folded.
Block Mountain is also called horst.
