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 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.
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 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.
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!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.

Identify features that all types of folds share and features that only some types of folds have?
It results in fractures, joints and faults, features that you will have the ... shapes of folds, but most can be classified into three basic types. ... see shortly, plunging folds do not share this characteristic.
What happens at a reverse fault?
Where fault blocks collide into each other. The most prominent example of this are the Himalayan Mountains formed by the collision of the Indian plate and the Eurasian Plate making what is called a folded mountain.

What is fault creep?
Fault creep is slow movement along a fault line with NO resulting earthquake.
Can you use fault in a sentence?
She was wonderful, save for a minor fault. The earthquake occured along a fault line.
Where tectonic plates collide folds and fault can become?
When tectonic plates collide, folds and faults can form. Folds occur when rocks are compressed and bend, while faults are fractures along which movement has occurred. These geological features are common at convergent plate boundaries, where tectonic forces cause intense pressure and deformation in the Earth's crust.
What fault is it that rocks become twisted and strained when they snag each other?
When rocks become twisted and strained due to snagging, it is due to the tectonic forces acting on them. These forces can cause rocks to deform and bend, resulting in various types of rock formations like folds and faults. The interaction between these rocks under stress can lead to their deformation and eventual displacement along fault lines.
When tectonic plates collide folds and faults become?

When tectonic plates collide folds faults can become?

How faults and folds influence construction of dams and tunnels?
Fault lines and land folds influence the construction of dams and tunnels by helping to decide where at in the land and run of the river the structure will be made, and also how strong the structure will need to be.
Differences between a fault and a fold?
Folds are the when the rock layers bend. Faults are breaks in the rock layers. Folds are called anticlines and synclines. Faults are called reverse faults, normal faults, or strike-slip faults.
When the earths crust bends but does not break is called?
When the Earth's crust bends but does not break, it is called flexural bending or flexure. This type of deformation can occur in response to tectonic forces, leading to the formation of features like folds, fault-related folds, and anticlines.
What is the stress that squeezes rock until it folds or breaks?
The stress that squeezes rock until it folds or breaks is called compressional stress. This type of stress occurs when forces push together in opposite directions, causing rocks to deform under pressure.
Are Ben Folds and Ben Folds Five the same band?
Ben Folds was the lead singer and piano player of the Ben Folds Five. Ben Folds now has a solo career.
What fault causes rocks to become twisted and strained when they snag each other?
The fault type that causes rocks to become twisted and strained when they snag each other is a strike-slip fault. In a strike-slip fault, rocks on either side of the fault move horizontally past each other, leading to twisting and straining along the fault zone. This type of movement is typical in transform plate boundaries such as the San Andreas Fault in California.
What is the birth name of Ben Folds?
Ben Folds's birth name is Benjamin Scott Folds.
Why are thrust fault reverse faults and folds commonly found in the same place?
Thrust faults, reverse faults, and folds are commonly found in the same place because they are all related to compressional tectonic forces. Thrust faults and reverse faults accommodate shortening in the Earth's crust, while folds form in response to the deformation caused by these compressional forces. Therefore, in areas experiencing significant compression, it is common to see a combination of both faulting and folding.
