How are oceanic ridges created
WebIf both plates are oceanic, as in the western Pacific Ocean, the volcanoes form a curved line of islands, known as an island arc, that is parallel to the trench, as in the case of the Mariana Islands and the adjacent Mariana Trench. If one plate is continental, the volcanoes form inland, as they do in the Andes of western South America. WebThe oceanic plates are the ones that make up the sea floor. The main difference between oceanic plates and continental plates is the type of crust found on each plate. Oceanic crust and continental crust are made out of different kinds of rock. The continental crust contains a lot of granite, which is an igneous rock.
