Oceanic Continental Plate Convergence Description: When an oceanic plate collides with a continental plate the oceanic plate slides under the continental plate. A trench known as an underwater valley forms where the tectonic plates meet.The plate that is sub-ducting goes farther, and pieces of it begin to melt off. This material that melts cools off and begins to crystallize into large rock below the continental plate. In some conditions the magma can come to the surface creating volcanoes.

Where does this occur? Oceanic continental convergence occurs between Juan De Fuca oceanic plate and the north American continental plate, this creates the cone shaped volcanoes on the west coast of north America. This is called the Cascadia subduction zone. This is responsible for the volcanic belt on the west coast of north America. 8 of 10 of these volcanoes have the possibility to become active. B.C's mountains are also produced by this collision.
