They bound many of the mountain ranges of the world and many of the rift valleys found along spreading margins.
In a normal fault the hanging wall moves.
Reverse faults form when the hanging wall moves up.
They are common at convergent boundaries.
Normal fractures in rock with no offset where there has been no motion are called.
The forces creating reverse faults are compressional pushing the sides together.
Normal fault s are common.
In fault normal dip slip faults are produced by vertical compression as earth s crust lengthens.
The hanging wall slides down the footwall.
The hanging wall slides down relative to the footwall.
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.
A downthrown block between two normal faults dipping towards each other is a graben.
The motion between the two is not always smooth and.
Low angle normal faults with regional tectonic significance may be designated detachment faults.
