What causes fault-block mountains?
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).
Which type of stress causes fault-block mountains quizlet?
Where two plates move away from each other, tension forces create many normal faults. When two of these normal faults form parallel to each other a block of rock is left lying between them. As the hanging wall of each normal fault slips downward, the block in between moves upward forming a fault-block mountain.
What Stress causes this type of fault form?
Compressional stress, meaning rocks pushing into each other, creates a reverse fault. In this type of fault, the hanging wall and footwall are pushed together, and the hanging wall moves upward along the fault relative to the footwall.
What are some examples of fault-block mountains?
Examples of fault-block mountains include the Sierra Nevada in California and Nevada, the Tetons in Wyoming, and the Harz Mountains in Germany.
What are 4 types of mountains?
There are 4 types of mountains, viz. fold mountains, block mountains and volcanic mountains.
What are five kinds of landforms caused by plate movement?
Name five kinds of landforms cause by plate movement. Anticlines, synclines, folded mountains, fault-block mountains and plateaus.
How does stress affect Earth’s crust?
Stress causes the build up of strain, which causes the deformation of rocks and the Earth’s crust. Compressional stresses cause a rock to shorten. Tensional stresses cause a rock to elongate, or pull apart. Shear stresses causes rocks to slip past each other.
What are the 3 fault types?
There are three main types of fault which can cause earthquakes: normal, reverse (thrust) and strike-slip. Figure 1 shows the types of faults that can cause earthquakes. Figures 2 and 3 show the location of large earthquakes over the past few decades.
Which type of fault is shown?
Which type of fault is shown? The type of fault shown is a left lateral fault. The movement was horizontal, making this a lateral or strike-slip fault. A viewer standing on one side of the fault, such as at the fence, would observe that the other part of the fence is located to the left.
