When the hanging wall moves up in relative to the footwall it is called a fault.
Fault the hanging wall moves down relative to the footwall.
Low angle normal faults with regional tectonic significance may be designated detachment faults.
Another type of fault is the thrust fault where ground on one side of the fault moves up and over adjacent ground.
Normal fault s are common.
Normal dip slip faults are produced by vertical compression as earth s crust lengthens.
The hanging wall moves downward relative to the footwall.
A normal fault occurs when the crust is extended.
An upthrown block between two normal faults dipping away from each other is a horst.
In a normal fault the hanging wall moves downward relative to the footwall.
These usually occur when tectonic forces cause tension that pulls rocks apart.
Normal faults usually form where tectonic plate motions cause tension.
Normal fractures in rock with no offset where there has been no motion are called.
Alternatively such a fault can be called an extensional fault.
They bound many of the mountain ranges of the world and many of the rift valleys found along spreading margins.
The hanging wall slides down relative to the footwall.
Tension is stress that pulls rocks apart.
A n fault forms when the hanging wall moves down relative to the footwall a.
