Metamorphic rocks are rocks that have been changed from their original form by immense heat or pressure. Metamorphic rocks have two classes: foliated and nonfoliated. What is a overlying rock? Surface salt structures are formed when underground salt diapirs pierce through the overlying rock.

WebbCorrect Answer:A. The pressure required for metamorphism can be generated by pressure from weight of overlying rock. Review Chapter 6, Section 3 in your textbook for more information. 46.
