Describe the pathway through the rock cycle in which igneous rock can become metamorphic rock.
Igneous is formed by magma, which cools and is eventually eroded down into sediment. Sediment is cemented and compacted together to form sedimentary rock. Sedimentary rock heats up and changes into metamorphic rock.
