Normal Fault
A normal fault
When the hanging wall of a fault slips down with respect to the footwall, it results in a normal fault. This type of faulting is associated with extensional tectonic forces, where the hanging wall moves downward in relation to the footwall, creating space between the two blocks.
The result is a normal fault, where the hanging wall moves down relative to the footwall due to extensional forces pulling the rock layers apart.
thrust
In a normal fault, the hanging wall moves down relative to the foot wall.
In a normal fault, the hanging wall moves down relative to the footwall, whereas in a reverse fault, the hanging wall moves up relative to the footwall.

That geological structure is called a normal fault, where the hanging wall moves down relative to the footwall. If the hanging wall slides up and over the footwall, it is known as a reverse fault.
No, a thrust fault is a type of reverse fault, where the hanging wall moves up and over the footwall. In contrast, a normal fault is a type of fault where the hanging wall moves down relative to the footwall.
In a normal fault, the hanging wall moves downward relative to the footwall, creating extensional forces. In a reverse fault, the hanging wall moves upward relative to the footwall, generating compressional forces.
A reverse fault is in a zone of compressional faulting, rocks in the hanging wall are pushed up relative to rocks in the footwall. A normal fault is in a zone of tensional faulting, rocks in the hanging wall drop down relative to those in a footwall forming a normal fault.
