Earth's Crustal Plates. Crustal plates (tectonic plates) are the outer shell of the Earth. Continental crust and oceanic crust are the two main types of plates. Large plates like the North American Plate is considered a continental plate but also contains oceanic crust. Continental crust which contains the interior of the large continents is much older than oceanic plates. Oceanic crust is constantly being created an destroyed around the Earth's surface.
Convergent Boundaries. Oceanic crust becomes cooler and denser as it spreads away from the mid-ocean ridge. Where two plates carrying oceanic crust meet at a trench, the plate that is more dense sinks under the other plate. Sometimes a plate carrying oceanic crust collides with a plate carrying continental crust. Oceanic crust is more dense than continental crust. The less dense continental crust canât sink under the more dense oceanic crust. Instead, subduction occurs as the oceanic plate sinks beneath the continental plate. When two plates carrying continental crust collide, subduction does not take place. Neither piece of crust is dense enough to sink very far into the mantle. Instead, the collision squeezes the crust into mighty mountain ranges.
