    Study Notes

    Plate Tectonic Processes

    • Processes of Plate Tectonics, include subduction, divergence, and transformation.
    • Divergence, occurs when plates separate, forming new crust.
    • Subduction, happens when one plate slides beneath another.
    • Transformation, occurs when plates slide past each other.
