The correct label the student should add to the arrow from the picture of obsidian (igneous rock) to the picture of slate (metamorphic rock) is heat and pressure. This is because slate is formed from the metamorphism of shale (a sedimentary rock), which involves heat and pressure, but in this context, the student is using the process of the rock cycle to illustrate how igneous rock can transform into metamorphic rock over time under specific conditions.
A student is using images of rocks to make a rock cycle diagram. The table describes the rocks the student is using:
