5.9: Plate Tectonics Theory

  • Page ID
  • Plate tectonics is the unifying theory of geology. Plate tectonics theory explains why:

    • Earth’s geography has changed through time and continues to change today.
    • some places are prone to earthquakes while others are not.
    • certain regions may have deadly, mild, or no volcanic eruptions.
    • mountain ranges are located where they are.

    Plate tectonic motions affect Earth’s rock cycle, climate, and the evolution of life.
