Question
How is the Earth's crust caused to fracture and fold?
✓

Answer

Deformation of rock involves changes in the shape and/ or volume of these substances. Changes in shape and volume occur when stress and strain causes rock to buckle and fracture or crumple into folds. A fold can be defined as a bend in rock that is the response to compressional forces. Folds are most visible in rocks that contain layering.
