GEOLOGY

Detailed explanation-1: -The Block Mountains are formed due to faults in the crust, which are planes where rocks have moved past each other, generating “block mountains”. A mountain can be formed when the rocks on one side of a fault rise relative to the other. Block mountains, or horsts, are raised blocks.

Detailed explanation-2: -Fault-block mountains often result from rifting, an indicator of extensional tectonics. These can be small or form extensive rift valley systems, such as the East African Rift zone. Death Valley in California is a smaller example.

Detailed explanation-3: -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).

Detailed explanation-4: -The answer is Block Mountain. Block Mountains: Block Mountains are created when large areas are broken and displaced vertically. It is the raised portion between two faults.

Detailed explanation-5: -Block mountains are also known as fault mountains. These mountains are formed due to natural faults (break up of bedrock) in the earth crust as a result of being extended and stretched by the tensile forces.
