What is causing faulting?

Faulting is caused by the stretching or compression of rock by tectonic plate movements


What is the movements in the crust that cause the faulting or folding of rock?

Tectonics.


What is faulting rock?

the breaking of rocks or displacing along the fracture.


What forms when the rock layers slip or slide along the crack?

Faulting.


What is the force that pulls rock apart?

Tensile stress.


Why would newer rock layers ever be below older rock layers?

Due to faulting or folding.


What are thrust fault mountains?

Rock that is too brittle to fold under heat and pressure, will break, calledthrust faulting. When older rock ends up on top of younger rock as a result of thrust faulting, the result is the formation of fault block mountains.


Explain that folding faulting and uplifting can rearrange the rock layers so the youngest is not always found on top?

Whenfolding, faulting, and uplifting occurs, the youngest rock layer can not always be on top. With folding the oldest rock layer could get folded over on top of a younger layer. When faulting occurs a younger rock layer can become "lower" or pushed more down in the rock layers that was originally shown. When these things happen, then rock layers can become out of order and the youngest layer is not always on the top of the layer.


Faulting and folding are both types of what-?

Crustal deformation. That is, when pieces of the Earth's crust change shape due to tectonic forces.


How does faulting of the earth's layer occur?

Faulting occurs when tensional forces act in opposite directions and cause one slab of the rock to be displaced up and the other slab down.


Geologic processes that assist in the formation of metamorphic rock include?

both tectonic folding and faulting


Where does most present -day faulting of rock occur?

At interfaces between moving parts of the lithosphere
