Quizplus · Accepted Answer

The image shows hot water reacting with the crust, which is the basis for hydrothermal metamorphism. Choice A, contact metamorphism, typically involves heat from an igneous intrusion rather than hot water. Regional metamorphism (Choice C) is caused by high pressure and temperature over a large area, while shock metamorphism (Choice D) occurs from the sudden impact of a meteorite or other large force. Neither of these processes is evident in the image.
