In which setting would regional metamorphism be most likely?
A)at shallow depths below an oceanic ridge or rift zone
B)at great depths in the crust where two continents are colliding
C)at shallow depths beneath the seafloor where water pressures are immense
D)at shallow depths along major transform faults in the continental crust

Question

Quizplus · Accepted Answer

Regional metamorphism occurs over large areas and is typically associated with mountain building and tectonic collisions between continents. The intense pressure and heat generated during these tectonic events can lead to significant changes in the mineralogy and texture of rocks. Therefore, option B, where two continents are colliding at great depths in the crust, is the most likely setting for regional metamorphism.
