Question

Quizplus · Accepted Answer

Regional metamorphism occurs at great depths in the crust, especially in areas where two continental plates are colliding. This process is associated with the formation of mountain ranges and involves both high pressure and high temperature, which alter the mineral composition and structure of the rocks.
