Describe the steps of how a metamorphic rock becomes an igneous rock.

• Magma → Cooling → Igneous Rock → Weathering & Erosion → Sedimentary Rock

• Melting → Cooling → Igneous Rock → Weathering & Erosion → Sedimentary Rock

• Sedimentary Rock → Heat & Pressure → Metamorphic Rock → Melting → Magma → Cooling → Igneous Rock
