- - - - converget/destructive boundary
        
        when 2 plates meet each other and colide, the denser plate ( normally the oceanic crust) goes down on the manttle and gets destroyed. This normally creates volcanoes and ocean trenches. If 2 continental plates meet they will create a mountain and if 2 oceanic plates meet the older one will go undernaeath the younger one.
      - constructive boundary
        
        Where two plates are moving away from eah other, exp: atlantic ridge, In this plates magma rises to fill in the gap that then cools and creates new crust.
      - transform boundry
        
        when 2 plates are moving sideways to each other or are moveing in the same direction or in opposite ways. exp: the cost of the USA. Crust is not created or destroyed. This is were earthquakes happen as tension is build.
