9 Destructive Plate Boundary – type 2 Ocean plate v. Continental plate (Sometimes called a SUBDUCTION ZONE)Ocean plate subducts as it is denserOcean trench e.g. Peru-Chile trenchCordillera range of Young Fold Mountains e.g. AndesAndesitic volcanic peaks e.g. Nevada del Ruiz
10 Destructive Plate Boundary – type 3 Continental plate v. continental Plate collisionA collision zoneMajor fold mountains e.g. Himalayas and High Plateau e.g. Tibete.g. Ocean plate carrying India drifted northwards until India collided with Eurasian plate.
11 Conservative Plate Boundary No volcanic featuresPlenty of earthquakes e.g. San Andreas fault.Fault line scarp slopesHorizontal movement faults
