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.
