Want this question answered?
Normal / extensional faulting creates horst and graben topography.
They have the same type of force on each fault and the tension is released Whenever the vertical stress (which mostly is because of gravity) is more than horizontal stresses, normal faults can be created or activated.
Strike slip faults and transform faults are associated with shear stress.
The stress in the southern part of the San Andreas Fault has a lot of collisions due to compression. The stress in the northern part gets separated because of tension, meaning one is causing them to move while the other is producing them.
I don"t know what the answer is!

stress along a fault line stress along a fault line
Normal fault forms tension stress. It is a stress state wherein a body of material is being stretched or expanded.
In a reverse fault the maximum principal stress is horizontal, compression causes reverse (thrust) faults.

normal fault
Shear Stress
Faulting is caused by stress in the rock layers, the stress can break and crack the rock causing a fault. There are two types of faults a normal fault and a reverse fault.
In a reverse fault the maximum principal stress is horizontal, compression causes reverse (thrust) faults.
Tectonic shear stress.
