When the hanging wall moves up in relative to the footwall it is called a fault.
The hanging wall moves downward relative to the footwall.
In a normal fault the hanging wall moves downward relative to the footwall.
An upthrown block between two normal faults dipping away from each other is a horst.
The hanging wall slides down relative to the footwall.
The hanging wall moves downward relative to the footwall.
Another type of fault is the thrust fault where ground on one side of the fault moves up and over adjacent ground.
When the hanging wall moves down in relative to the footwall it is called a fault.
These usually occur when tectonic forces cause tension that pulls rocks apart.
Normal dip slip faults are produced by vertical compression as earth s crust lengthens.
Along a normal fault the hanging wall moves down relative to the footwall.
Low angle normal faults with regional tectonic significance may be designated detachment faults.
Tension is stress that pulls rocks apart.
A downthrown block between two normal faults dipping towards each other is a graben.
Normal faults usually form where tectonic plate motions cause tension.
Normal fault s are common.
