10.4 Sketch and briefly describe the relative motion of rock bodies located on opposite
Deformation (de = out, forma = form) is a general term for the changes in the shape or position of a rock body in response to differential stress.
Rock structures include folds (wave-like undulations), faults (fractures along which one rock body slides past another), joints (cracks), and small-scale structures associated with metamorphic rocks such
Whenever the stresses acting on a rock body exceed its strength, the rock will deform-usually by one or more of the following processes: folding, flow- ing, fracturing, or faulting.
Confining pres- sure does not, however, change the shape or orienta- tion of a rock body.
