When energy from stress is used to deform rock and give it a permanent new shape, such as a fold, this process is called:
A) elastic deformation.
B) fracture.
C) plastic deformation.
D) slippage.

Question

Quizplus · Accepted Answer

Plastic deformation refers to the permanent change in shape of a rock due to the application of stress, such as folding. Elastic deformation refers to the temporary deformation of a rock that returns to its original shape when the stress is released. Fracture refers to the breaking of a rock along a fault or joint, and slippage refers to the movement of one rock mass past another along a fault.
