If the hanging wall drops relative to the footwall you have a normal fault.
Footwall and hanging wall normal fault.
An upthrown block between two normal faults dipping away from each other is a horst.
If you imagine undoing the motion of a normal fault you will undo the stretching and thus shorten the horizontal distance between two points on either side of the fault.
The rift basin at the bottom of the north.
Normal fault a type of fault in which the hanging wall moves down relative to the footwall and the fault surface dips steeply commonly from 50 o to 90 o.
Normal dip slip faults are produced by vertical compression as earth s crust lengthens.
Low angle normal faults with regional tectonic significance may be designated detachment faults.
This sliding downward of normal faults creates rifts valleys and mountains.
A downthrown block between two normal faults dipping towards each other is a graben.
Normal fault s are common.
The hanging wall is to the left of the fault and the footwall to the right.
In a normal fault the hanging wall moves downward relative to the footwall.
A type of fault in which the hanging wall moves down relative to the footwall and the fault surface dips steeply commonly from 50o to 90o.
Normal faults occur in areas undergoing extension stretching.
