Question

Block mountains form along which type of geological landform?

Answer 1

Answer:

A. Fault blocks

Explanation:

The block mountains are formed by pieces of the crust that breaks down and pieces are pushed up by the movement of the crust around them.  These type of mountains usually have a steep and a slope side, due to the irregular nature of the fracture.  Example of such mountains are the Sierra Nevada mountains in North-America.

They're not caused by the collision of two tectonic plates, like most of the mountains of our planet.

Answer 2

Answer: A. fault blocks

Explanation: Fault-block Mountains - Fault-block mountains are formed along fault lines (the edge between plates).

The huge chunks of rock on either side of the fault are called fault blocks. As the tectonic plates

move, some of the fault blocks are pushed up, while others are pushed down. This difference in

elevation (height) forms fault block mountains. The Sierra Nevada Mountains in the western United

States are fault-block mountains.
