  • Plate Margins
    • Destructive (platwes move towards each other)
      • Collision
        • continental + continental
        • Fold Mountains
        • Afican and Eurasian (Alps)
      • Subduction
        • Oceanic + continental plates
        • Ocenic = denser = sinks beneath
        • Oceanic crust = forms magma = volcano some distance away
        • Philippines and Pacific
    • Constructive
      • PLates move away from each other
        • Usually Oceaqnic plates = Ocean trenches
        • The gap where there is no solid crust forms volcanoes as mage rushes up
      • North America and Eurasian
    • Earthquakes
    • Conservative
      • PLtes slide plast each other or at different speed
        • PLates tend to get stuck and the pressure is realeased to form earthquake
      • North America and Pacific (San Andreas Fault)
