Plate Tectonics Theory

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.
