What do reverse faults create?
(A) Reverse faults display severe damage in the form of landslides over the fault trace caused by the inability of the hanging wall to support the overhang caused by the fault displacement, folds, and compression features within the fractured hanging wall, and compressional block tilting.
What effects do these faults have?
One of the main effects of the faults on topography is that they very often result in the development of distinct types of steep slopes which are aptly called fault scarps. Three types of fault associated scarps are often recognized- fault scarps, fault-line scarps and composite-fault scarps.
Why do these faults happen?
Faults are fractures in Earth’s crust where movement has occurred. Sometimes faults move when energy is released from a sudden slip of the rocks on either side. It forms when rock above an inclined fracture plane moves downward, sliding along the rock on the other side of the fracture.
What happens to rock along a reverse fault?
Compare the image to the right with the normal fault above. Along a reverse fault one rocky block is pushed up relative to rock on the other side. All at once, CRACK!, the rock breaks and the two rocky blocks move in opposite directions along a more or less planar fracture surface called a fault.
Are rock layers still continuous in a reverse fault?
Are the rock layers still continuous? No – they are now broken by the fault 4.
What do we call a down drop block of the crust bounded by normal faults on each side?
grabens
What type of stress is placed on a normal fault reverse fault strike slip fault?
A reverse fault is a dip-slip fault in which the hanging-wall has moved upward, over the footwall. Reverse faults are produced by compressional stresses in which the maximum principal stress is horizontal and the minimum stress is vertical.
What can you infer about the different kinds of faults?
There are three different types of faults: Normal, Reverse, and Transcurrent (Strike-Slip). Normal faults form when the hanging wall drops down. The forces that create normal faults are pulling the sides apart, or extensional. Reverse faults form when the hanging wall moves up.
What do you think is the relationship between faults and earthquakes?
Earthquakes occur on faults – strike-slip earthquakes occur on strike-slip faults, normal earthquakes occur on normal faults, and thrust earthquakes occur on thrust or reverse faults. When an earthquake occurs on one of these faults, the rock on one side of the fault slips with respect to the other.
What is the highest landform on earth?
Mount Everest
What type of stress causes fault block mountains?
Fault Block Mountains: Tension force pulls rock apart causing normal faults. Two normal faults cut through a block of rock, the hanging wall between each slips downward, the rock between moves upward, forming a fault-block mountain.
