Diastrophisms
Diastrophism is a general term that refers to deformation of the Earth's crust, and more specifically to folding and faulting. Diastrophism can be considered part of geotectonics. Diastrophism comes from the Greek word meaning a twisting.
The term covers movement of solid (plastic) crust material, as opposed to movement of molten material which is covered by volcanism. Movement causes rock to be bent or broken. The most obvious evidence of disastrophic movement can be seen where sedimentary rocks have been bent, broken or tilted. Such non-horizontal strata provide visual proof of movement.
