Folding and faulting are both caused by stress in the Earth's crust exceeding the strength of the material. However there are differences in the confining stresses and or temperatures at which these two processes occur.

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, usually within the asthenosphere or mesosphere. All of these factors 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

A Fold is the process of bending and a Fault is the process of cracking.

A Fold is the bending of rocks in the Earth as a result of compressional tectonic forces such as continental collisions. This occurs at depth in the Earth. Folds are most visible in rocks that contain layering.

The simplest type of fold is called a monocline. This fold involves a slight bend in otherwise parallel layers of rock. More complex fold types can develop in situations where lateral pressures become greater. The greater pressure results in anticlines and synclines that are inclined and asymmetrical.

A Fault is the fracturing of rocks in the Earth causing breakage and slip parallel to the fracture. Caused by compressional, extensional and shear forces. Occurs close to surface of the Earth.

Faults form in rocks when the stresses overcome the internal strength of the rock resulting in a fracture. A fault can be defined as the displacement of once connected blocks of rock along a fault plane. This can occur in any direction with the blocks moving away from each other. Faults occur from both tensional and compressional forces.

A fault is a discontinuity in the layer.

A fold is a bending of the layer.

Fault block mountains are often created through rifting, which is an indication of tensional tectonic forces. Fault block mountains are primarily the result of faulting and folding.


What are the meanings of terms differ folding and fault?

Differ means be unlike or dissimilar or disagree. In chemistry, folding is the process by which a molecule assumes its shape or conformation. In geology, a fault is a planar fracture or discontinuity in a volume of rock, across which there has been significant displacement along the fractures as a result of earth movemen


What type of fault is likely to form in an area where rock layer has been folded?

Probably reverse fault because folding is the result of compressional stres and reverse faults are caused by compression


Are folding treadmills cheaper than those that dont fold?

Folding treadmills are not cheaper than treadmills that do not fold. This is because the price of both folding and non-folding treadmills vary between companies, so where a folding treadmill is cheap in one store, may not be cheaper in another store.

What does reconcile differences mean?

I think you mean irreconcilable differences. If so, irreconcilable differences are differences between spouses that are considered sufficiently severe to make married life together more or less impossible. In a number of states, irreconcilable differences is the accepted ground for a no-fault divorce. As a practical matter, courts seldom, if ever, inquire into what the differences actually are, and routinely grant a divorce as long as the party seeking the divorce says the couple has irreconcilable differences.
