An upthrown block between two normal faults dipping away from each other is a horst.
In a normal fault the hanging wall moves.
The hanging wall slides down the footwall.
A n fault forms when the hanging wall moves down relative to the footwall a.
Reverse faults form when the hanging wall moves up.
In fault normal dip slip faults are produced by vertical compression as earth s crust lengthens.
In a normal fault the hanging wall moves downward relative to the footwall.
Normal fractures in rock with no offset where there has been no motion are called.
They are common at convergent boundaries.
Together normal and reverse faults are called dip slip faults because the movement on them occurs along the dip direction either down or up respectively.
The motion between the two is not always smooth and.
They bound many of the mountain ranges of the world and many of the rift valleys found along spreading margins.
In this picture of a normal fault the valley is the hanging wall and the mountain is the footwall.
The forces creating reverse faults are compressional pushing the sides together.
A downthrown block between two normal faults dipping towards each other is a graben.
