In a normal fault the hanging wall moves downward relative to the footwall. When the hanging wall moves down in relative to the footwall it is called a fault. Normal dip slip faults are produced by vertical compression as earth s crust lengthens.

The hanging wall moves downward relative to the footwall.

Fault the hanging wall moves down relative to the footwall.

A n fault forms when the hanging wall moves down relative to the footwall a. Alternatively such a fault can be called an extensional fault. Normal fault s are common. A normal fault occurs when the crust is extended.

Another type of fault is the thrust fault where ground on one side of the fault moves up and over adjacent ground. Tension is stress that pulls rocks apart. Normal faults usually form where tectonic plate motions cause tension. Low angle normal faults with regional tectonic significance may be designated detachment faults.

Along a normal fault the hanging wall moves down relative to the footwall. The hanging wall slides down relative to the footwall. These usually occur when tectonic forces cause tension that pulls rocks apart. Normal fractures in rock with no offset where there has been no motion are called.

When the hanging wall moves up in relative to the footwall it is called a fault. They bound many of the mountain ranges of the world and many of the rift valleys found along spreading margins. An upthrown block between two normal faults dipping away from each other is a horst. A downthrown block between two normal faults dipping towards each other is a graben.
