D) shock

Quizplus · Accepted Answer

The figure shows hot water reacting with the crust, which is the basis for hydrothermal metamorphism. Contact metamorphism occurs when rocks are heated by contact with an igneous intrusion, regional metamorphism occurs due to pressure and temperature changes over a large area, and shock metamorphism occurs due to the sudden impact of meteorites. However, none of these processes are indicated in the figure. Therefore, the best choice is hydrothermal metamorphism (B).
