C) Burial
D) Hydrothermal
E) Shock

Question

Quizplus · Accepted Answer

Regional metamorphism is associated with the large-scale tectonic movements that result in the formation of mountain belts, and occurs at significant depths within the Earth's crust, generally greater than 5 km. Contact metamorphism (A) occurs when rock is heated by intruding magma, Burial metamorphism (C) occurs when sediments are buried by overlying sediments, and Hydrothermal metamorphism (D) occurs when hot, mineral-rich fluids circulate through rocks. Shock metamorphism (E) occurs when high-pressure shock waves from meteorite impacts or nuclear explosions cause sudden, intense changes in rock structure. None of these types of metamorphism typically occur at depths greater than 5 km.
