What can fault and folds become?

Answer 1

Folding and faulting are both caused by stress in the Earth's crust exceeding the strength of the material. However folding tends to occur at small strain rates (the speed at which the material changes shape or is squashed is very small), at higher confining pressures and with higher temperatures at greater depths in the earth (typically the asthenosphere and mesosphere) all of which act to stop the formation of fractures within the material leading to ductile deformation which is why the rocks can fold rather than break.

Faulting occurs where strain rates are large and there are relatively low temperatures and confining pressures at shallower depths within the earth's lithosphere. These conditions allow fractures to propagate through the rock causing faulting.

Block Mountains

• Block mountains form when the layers of the Earth's crust are forced upward near fault lines. Fault-block mountains have a steep, sharp front side and a gentler, sloping back. Examples of block mountains are the Teton Range of Wyoming, the Alps in Europe and the Urals. California's Sierra Nevada is a 350-mile long block of granite containing Mt. Whitney, the highest mountain peak in the lower 48 states. This granite mountain was lifted during the formation of the Basin and Range Province, centered in Nevada and stretching from southern Oregon to west Texas.

Rift Valley

• When a depression appears between two block mountains, that depression is called a rift valley, which can be thousands of miles long. In the United States, one example of these flat-bottomed valleys is Death Valley in California. Some of the largest rift valleys include the East African Rift Valley, Russia's Baikal Valley, Germany's Rhine Valley and the Red Sea. Ocean rift valleys occur where tectonic plates on the seafloor spread apart. The largest lakes in the world are all found in rift valleys.

Folded Mountains

• Folded mountains form when crust and rock formations lift and fold after tectonic plates collide. These mountains are generally less rough-looking and are formed adjacent to the sharper, thrust-faulted block mountains. The Appalachian Mountains in the eastern United States are folded mountains. Other examples include the Rocky Mountains, Himalayas in Asia, the Andes in South America, the Jura Mountains near the Alps, and the Zagros Mountains in northwestern Iran.

Strike Fault

• A strike-slip fault happens where geologic stresses occur in two tectonic plates parallel to each other. The best known example of a strike-slip fault is the 800-mile long San Andreas fault in California, created by the Pacific plate colliding with the North American plate. The San Andreas and Garlock faults intersect in Southern California. At this point, the movement of the Earth's crust at the Garlock fault bends the San Andreas fault into an "S" shape. This pushing together of the crust has resulted in the formation of the San Gabriel Mountains north of Los Angeles.

hope it can help!

Answer 3

Folding and Faulting is the result of Stress and Strain and this can be caused by things such as tectonic activity, when rocks are forced towards each other and because the rocks on the earths surface are cold and brittle, they fracture.

They can become a mid-ocean ridge
