Factors that influence the strength of a rock and how it will deform include temperature, confining pressure, rock type, and time.. Deformation. Whether a material bends or breaks depends on . h. ow much stress is applied to the material.. Deformation. Process by which the shape of a rock changes because of stress.. Objectives:. Describe. What is a Fold?. A fold is a bent rock layer or series of layers that were originally horizontal and subsequently deformed.. Due to compression forces.. They are most visible in rocks that have layers.. 16 air before landing on your back with your ski in your ear.
