One student made the incomplete diagram shown below to represent the relationship between sediment, igneous rocks, and metamorphic rocks:
three ovals, labeled from left to right, metamorphic rock, sediment, and igneous rocks respectively.
Which of these is the correct next step to complete the diagram?
Put an arrow labeled heat and melt, pointing from igneous rocks to sediment.
Put an arrow labeled deposition and lithification, pointing from metamorphic rock to sediment.
Put an arrow labeled cools and crystallizes, pointing from igneous rocks to sediments.
Put an arrow labeled heat and pressure, pointing from sediment to metamorphic rock.
