How might metamorphic rock be formed as a result of plate motion?
Plate motion causes oceanic plates to be forced deep under continental plates. The ocean plate along with its sediment cover are compressed, forming metamorphic rock.
Plate motion causes molten rock to rise to the earth’s surface through volcanic activity and when it cools, metamorphic rock forms.
Plate motion forces molten rock to move to new areas where cooling occurs deep underground, forming metamorphic rock.
Plate motion causes rock layers from beneath the earth’s surface to be exposed. Weathering and compaction ultimately reshape the rock, forming metamorphic rock.
The correct answer is: Plate motion causes oceanic plates to be forced deep under continental plates. The ocean plate along with its sediment cover are compressed, forming metamorphic rock.
Explanation: This process, known as subduction, occurs when one tectonic plate is pushed below another. The intense heat and pressure from being buried deep beneath the other plate causes the minerals in the oceanic plate and its sediments to undergo metamorphism, transforming them into metamorphic rock. This is a key mechanism of metamorphic rock formation related to plate tectonics.
