What type of stress is most likely to occur at the San Andreas Fault?
Shear Stress Friction between the plates grinding past one another produces the stress. Shear stress is associated with transform faults, which may also be called strike-slip or slip-strike faults. Perhaps the most well-known example of shear stress is the strike-slip fault known as the San Andreas in California.
How reverse fault is formed?
A type of fault formed when the hanging wall fault block moves up along a fault surface relative to the footwall. Such movement can occur in areas where the Earth’s crust is compressed.
What are the characteristics of reverse fault?
Reverse faults have a characteristic topographic signature caused by uplift of the hanging wall and associated folding above the fault, producing lobate ridges (Schultz et al. 2010).
What landforms do reverse fault form?
Reverse faults are common in regions where the crust is being compressed and thickened as a result of plates converging. Thrust faults are even more common at convergent plate margins, where plates are moving toward one another, compressing, and often forming high mountains.
What is the angle of fault plane with the horizontal called?
Explanation: The dip of the fault is its inclination with the horizontal as measured in a vertical plane at right angles to the strike of the fault.
What is block faulting?
A type of normal faulting in which the crust is divided into structural or fault blocks of different elevations and orientations. It is the process by which block mountains are formed.
How is a fault block mountain formed?
Fault-block mountains are formed by the movement of large crustal blocks along faults formed when tensional forces pull apart the crust (Figure 3). Tension is often the result of uplifting part of the crust; it can also be produced by opposite-flowing convection cells in the mantle (see Figure 1).
What is an example of a fault block mountain?
Examples of fault-block mountains include the Sierra Nevada in California and Nevada, the Tetons in Wyoming, and the Harz Mountains in Germany.
What type of stress causes fold and thrust mountains?
Compressive stresses cause: Low-angle thrust faults • High uplifted mountain ranges • Folding of rock layers Page 25 Fold and Thrust Mountains • Collision of India with Eurasia caused compressive stresses.
Which two types of faults can result in mountains?
Normal and Reverse Faults because they both have vertical movement. Vertical movement can push rock up. Two types of faults can result in mountains.
