Ductile deformation results in a change of the shape of solids without breaking them. This can also be said of elastic deformation. Watch both the Elastic Deformation and Ductile Deformation topics in the Reock Deformation Animation, and compare the two types of deformation. How is ductile deformation different from elastic deformation? Choose one or more: OA. Once the stress is removed, rocks that have undergone ductile deformation return to their original shape. B. Ductile deformation can result in tight folds,...
