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.
Why do fault zones form at boundaries? Because the Earth's crust is composed of not one solid layer like a shell, but many pieces, like in a puzzle. These plates are floating on layer of magma. So at these fault lines it is easier for lava to get through the crust and cause volcanoes and such....
