WebThe “morph” in metamorphic literally means to change. Basically, the original rock changes due to extreme heat—over 400°—and very high pressure. Under the Earth’s surface, physical and chemical changes transform the original rock into a metamorphic rock. These changes occur in the root of a mountain chain or volcano.
