What are the correct steps in the transformation of a sedimentary rock into a metamorphic rock?
A)rock eroded away and deposited in ocean basin → rock pulled into subduction zone and melted
B)rock eroded away and deposited in ocean basin → rock buried under many layers of sediments
C)rock eroded away and deposited in ocean basin → volcano erupts through ocean floor and melts rocks
D)rock eroded away and deposited in alluvial fan → 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 burying the rock deeply under many layers of sediments, subjecting it to pressure and high temperatures, and causing it to recrystallize and change its mineral composition. Option B accurately describes this process. The other options either involve melting the rock (A, C), which would result in an igneous rock, or melting due to an intrusion (D), which would result in a contact metamorphic rock.
