tectonic plates

• Tectonic plates


  Random shapes that the Earth's outer layer (the crust) is divided into
• Plate margins/boundaries


  Where the tectonic plates meet
• Tectonic plates are constantly moving
• Tectonic plates get stuck

  When they finally move, they release a lot of energy in the form of seismic waves, causing an earthquake
• Earthquakes are unpredictable
