D)Extrusive metamorphism.

Question

Quizplus · Accepted Answer

Contact metamorphism occurs when rocks come into contact with an igneous intrusion, causing them to be exposed to the extreme heat and pressure of the magma. This results in the alteration of the rocks' mineralogy and texture, creating metamorphic rocks. Regional metamorphism, on the other hand, occurs over a larger area and is the result of tectonic forces, while intrusive and extrusive metamorphism are not commonly used terms in geology.
