The agents of metamorphism are ________.
A) uplifting and folding
B) foliation and deposition
C) contact and regional deformation
D) heat, pressure, and chemical fluids

Question

Quizplus · Accepted Answer

Metamorphism occurs due to the combined effect of heat, pressure, and chemical fluids. Heat and pressure cause the minerals in the rock to recrystallize, while chemical fluids can alter the mineralogy and textures of the rock. Uplifting and folding are tectonic processes that can contribute to the metamorphic process, but they are not the agents of metamorphism themselves. Foliation and deposition are not agents of metamorphism, but rather are textures that result from the metamorphic process. Contact and regional deformation are specific types of metamorphism that occur in different settings, but they are not the agents of metamorphism themselves.
