PPT-Deforming the Earth’s Crust

Deformation the process by which the shape of a rock changes because of stress is called deformation compression stress that occurs when forces act to squeeze an object at a convergent boundary. 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:.

Geologic processes that occurred in the past can be explained by current geologic processes. Erosion and weathering that happens today must have been the same millions of years ago. Faults and Folds.
