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