Plate Margins

Destructive Margins:- Destructive margins are where two plates are moving towards each other. A destructive plate is where an oceanic plates meets a continental plate, the oceanic plate is forced down into the mantle and destroyed. This often creates volcano's and ocean trenches (very deep scetions of the ocean floor where the oceanic plate goes down).
