Question

How are folds and faults created?

Answer 1

When the Earth's crust is pushed together via compression forces, it can experience geological processes called folding and faulting. Folding occurs when the Earth's crust bends away from a flat surface. Faulting happens when the Earth's crust completely breaks and slides past each other.

Answer 2

a)Folding occurs when tectonic processes put stress on a rock, and the rock bends, instead of breaking. This can create a variety of landforms as the surfaces of the folded rocks are eroded.

b)A fault is formed in the Earth's crust as a brittle response to stress. Generally, the movement of the tectonic plates provides the stress, and rocks at the surface break in response to this. Faults have no particular length scale.
