When a rock along a fault line experiences so much pressure it changes shape (looks almost curved)

• elastic deformation

• elastic rebound

• elastic transfiguration

• elastic convection

When a rock along a fault line experiences so much pressure it snaps and releases energy, returning back to its original shape.

• elastic deformation

• elastic rebound

• elastic transfiguration

• elastic convection
