  1. Rock Cycle Explanation:
    1. Formation:
    – Igneous rocks form from cooled magma/lava.
    – Sedimentary rocks form from sediment deposition and compaction.
    – Metamorphic rocks form from existing rocks altered by heat/pressure.

    2. Transformation:
    – Igneous rocks can weather into sediments.
    – Sediments can compact to form sedimentary rocks.
    – Any rock type can undergo metamorphism to become metamorphic rocks.

    3. Recycling:
    – Melting and solidification form new igneous rocks.
    – Weathering and erosion form sediments.
    – Metamorphism creates new metamorphic rocks.

    The rock cycle depicts how rocks transform between types through geological processes, demonstrating Earth’s dynamic nature.
