Explanation:

Fault-block mountains are formed by the movement of large crustal blocks along faults formed when tensional forces pull apart the crust (Figure 3). Tension is often the result of uplifting part of the crust; it can also be produced by opposite-flowing convection cells in the mantle (see Figure 1).
