## Which can be caused by a normal fault?

Tensional stress is when rock slabs are pulled apart from each other, causing normal faults. With normal faults, the hanging wall slips downward relative to the footwall. These rocks move like your hands do when you rub them together to warm up. The movement along faults is what causes earthquakes.

## Can normal faults create mountains?

When continental crust is pulled apart, it breaks into blocks. These blocks of crust are separated by normal faults. The blocks slide up or down. The result is alternating mountain ranges and valleys.

What are faults caused by?

A fault is formed in the Earth’s crust as a brittle response to stress. Generally, the movement of the tectonic plates provides the stress, and rocks at the surface break in response to this. Faults have no particular length scale.

### Where are normal faults found?

Normal faults are often found along divergent plate boundaries, such as under the ocean where new crust is forming. Long, deep valleys can also be the result of normal faulting.

### Which is an example of reverse fault?

Reverse faults are dip-slip faults in which the hanging wall moves up relative to the footwall. Reverse faults are the result of compression (forces that push rocks together). The Sierra Madre fault zone of southern California is an example of reverse-fault movement.

What are 4 different types of faults?

There are four types of faulting — normal, reverse, strike-slip, and oblique. A normal fault is one in which the rocks above the fault plane, or hanging wall, move down relative to the rocks below the fault plane, or footwall. A reverse fault is one in which the hanging wall moves up relative to the footwall.

#### What does a normal fault look like?

Normal faults create space. These faults may look like large trenches or small cracks in the Earth’s surface. The fault scarp may be visible in these faults as the hanging wall slips below the footwall. In a flat area, a normal fault looks like a step or offset rock (the fault scarp).

#### Where does a normal fault occur?

divergent plate boundaries
Normal Faults: This is the most common type of fault. It forms when rock above an inclined fracture plane moves downward, sliding along the rock on the other side of the fracture. Normal faults are often found along divergent plate boundaries, such as under the ocean where new crust is forming.
