Use the simplified rock-cycle model below. The rock cycle does not have a fixed starting point, and rocks can change types over time. Model (arrows show possible changes): Magma/Lava --(cooling)--> Igneous Rock Igneous Rock --(weathering & erosion)--> Sediments --(compaction)--> Sedimentary Rock Sedimentary Rock --(heat & pressure)--> Metamorphic Rock Metamorphic Rock --(melting)--> Magma/Lava (Also: Igneous Rock --(heat & pressure)--> Metamorphic Rock) A student finds a rock that formed when melted material cooled and hardened after a volcanic eruption. According to the model, which process formed this rock?
