Question

What are the three types of faults?

Answer 1

The correct answer is Normal, Reverse, and Transcurrent.

Step-by-step explanation:

A fault is a geological phenomenon caused by the movement of tectonic plates that generates a crack in the Earth's crust.

The types of tectonic faults that exist are:

• Normal: It is a flat fracture or it has a slight curve. It shifts due to the stress of the rocks on the opposite sides of the crack.

• Reverse: It is a common movement where one of its sides moves up and is placed on the other. An example of this is Rocky Mountains, Himalayas.

• Transcurrent: Its shape is usually curved and has walls that move inside the crust and end when extended or folded.

Answer 2

There are three different types of faults:

1. Normal

2. Reverse

3. Transcurrent (Strike-Slip).

Step-by-step explanation:

1. Normal faults form when the hanging wall drops down. The forces that create normal faults are pulling the sides apart, or extensional.

2. Reverse faults form when the hanging wall moves up. The forces creating reverse faults are compressional, pushing the sides together.

3. Transcurrent or Strike-slip faults have walls that move sideways, not up or down.
