Dynamothermal (regional) metamorphism occurs when ________. A. rock becomes deeply buried during continental collision and mount
ain building B. regression of the sea leads to erosion of sedimentary cover on a body of rock C. the upper surface of a body of rock develops a thick soil profile D. a pluton causes metamorphism in a small surrounding region
A. rock becomes deeply buried during continental collision and mountain building
Explanation:
These rocks were typically exposed to tectonic forces and associated high pressures and temperatures. Regional metamorphism occurs when rocks are buried deep in the crust.
