When a rock is buried to increasing depth it is subject to increasingly greater temperature and pressure and will undergo _____.
A) contact metamorphism
B) prograde metamorphism
C) shock metamorphism
D) retrograde metamorphism
E) hydrothermal metamorphism

Question

Quizplus · Accepted Answer

Prograde metamorphism occurs when a rock is buried to increasing depths and subjected to higher temperatures and pressures over time. Contact metamorphism occurs when a rock is heated by the proximity to an igneous intrusion. Shock metamorphism occurs when a rock is subjected to a sudden shock, such as during a meteorite impact. Retrograde metamorphism occurs when a rock is exposed to decreasing temperatures and pressures after a period of prograde metamorphism. Hydrothermal metamorphism occurs when hot water reacts with and alters a rock.
