2. Earthquake

   • mesure ment
     • Richter scale: Magnitude 1-10
     • Mercallin scale: Intensitive 1-12
   • 3 way movement
     • Apart
     • together
     • sliding over the persific continental crust
   • couses of plate movement
     • Constructive
       • produces more land (can make volcanoes)
     • Conservative
       • Sliding past each other ( will make earthquackes)
     • Destructive
       • sliding persific plate under the land plate that will destroy land (can couse earthquackes and volcanoes)
     • Coillision Zone
       • 2 land plates pressing against each other ( creating mountins and volcanoes

3. Facts about the ring of fire

   • 40,000km long line
   • 452 volanoes
   • has the shape of a horse shoe
