Answer:
Elastic deformation
Explanation:
When rock retains its new shape (without fracturing) after stress has been removed, it has undergone elastic deformation.
Elastic deformation is the process in which the object under temporary stress regains its original shape after the stress is removed. The stress must be low and not strong enough that it can create fracture and permanent damage to the object. for example, we can stretch a rubber band by applying some force and when we remove the force, the rubber band comes back to its original length and shape.
