D)on the rims of large meteorite impact craters

Question

Quizplus · Accepted Answer

Regional metamorphism is the type of metamorphism that occurs over a widespread area and is associated with tectonic activity such as mountain building or collision of two continents. The intense pressure and temperature changes that occur during these processes lead to the formation of metamorphic rocks. Therefore, the most likely setting where regional metamorphism would occur is at great depths in the crust where two continents are colliding.
