Answer to Question 1

Magma rises at mid-oceanic ridges and heats the adjacent rocks, producing contact metamorphism.
Fluids emanate from the rising magma, and the magma reacts with seawater to produce metal-bearing
hydrothermal solutions.



Answer to Question 2

Metamorphic rocks formed near Earth's surface along an oceanic-continental convergent plate
boundary result from low-temperature, high-pressure conditions. As a subducted oceanic plate
descends, it is subjected to increasingly higher temperatures and pressures that result in higher-grade
metamorphism
