Question

why folding and faulting is one of the main cause behind earthquakes

Answer 1

folding and faulting creates a abnormal tension inside the earth's crust which leads to unequal levelling of the mantle and hence it forms pressure on the surface of earth. If such tension is exerted under the land of any reservoir, it leads to collapsing of it.

Folding inside earth's crust take many years. Fault in the land structure makes the land hollow or unhabitable,.. hence it causes earthquake.

Answer 2

Answer:

Explanation:Internal horizontal and vertical movements due to compressionable and tensional forces causes folding and faulting of rocks inside the earth's crust ,this causes displacement in the rocks in the crust such an unbalance causes earthquakes for example,in 1906 san andreas fault of california [USA]gave rise to a major earthquake that measured 8.3 on the richter scale and broke the earth's surface along a 402km length.
