A normal fault moves because it is under tension.

A normal fault moves because it is under tension. In a normal fault, the hanging wall moves down relative to the footwall due to the pulling apart of the Earth's crust, creating space and tension that cause the fault to move.
A normal fault moves because of tension. In this type of fault, the hanging wall moves down relative to the footwall due to the stretching and pulling apart of the Earth's crust.
Normal Thrust
A normal fault may form when rocks are pulled apart due to tension. In a normal fault, the hanging wall moves down relative to the footwall.
A tension fault occurs when there is stretching or pulling apart of the Earth's crust, which can lead to earthquakes as the rock breaks under the stress. This type of fault is associated with tectonic plate movements and occurs along divergent plate boundaries.
A reverse fault is under compression. In a reverse fault, the hanging wall moves up relative to the footwall due to compression forces in the Earth's crust. This type of fault is common in areas with convergent tectonic plate boundaries.
