Explanation:

Each arrow corresponds to the geological process that transforms one rock type (or magma) to another:

• A: Magma cools to form igneous rock.
• B: Igneous rock melts into magma.
• C: Igneous rock breaks down into sediment via weathering/erosion.
• D: Sediment lithifies into sedimentary rock via compaction/cementation.
• E: Sedimentary rock breaks down into sediment via weathering/erosion.
• F: Sedimentary rock becomes metamorphic rock via heat/pressure.
• G: Metamorphic rock melts into magma.
• H: Metamorphic rock breaks down into sediment via weathering/erosion.
• I: Metamorphic rock forms from igneous rock via heat/pressure.
