Identify the correct steps in the transformation of a sedimentary rock into a metamorphic rock.
A) rock eroded away and deposited in ocean basin $\rightarrow$ rock pulled into subduction zone and melted
B) rock eroded away and deposited in ocean basin $\rightarrow$ rock buried under many layers of sediments
C) rock eroded away and deposited in ocean basin $\rightarrow$ volcano erupts through ocean floor and melts rocks
D) rock eroded away and deposited in alluvial fan $\rightarrow$ rock buried deeply and melted by intrusion

Question

Quizplus · Accepted Answer

The correct steps in the transformation of a sedimentary rock into a metamorphic rock involve burial under many layers of sediments, which leads to increased heat and pressure that cause the minerals in the rock to recrystallize and change their form. Options A, C, and D involve different processes such as melting and intrusion that would lead to the formation of igneous rocks, not metamorphic rocks.
