Oceanic crust is composed of magma that erupts on the seafloor to create basalt lava flows has relatively low density, continental crust rises higher on the mantle than oceanic crust,  6 Oct 2017 Continental Crust: Granitic. Pay special attention to the densities  Although the hot rock of the mantle is a solid, under the tremendous pressure of the crust and overlying rock of the mantle, creates a chain of volcanoes or volcanic islands, a track marking the position of the plume relative to the moving plate. Compared to the rest of the layers, the crust is relatively thin and light. Continental crust contains some very old rocks that were  Continental crust is found on the land masses on the Earth's surface that isn't covered by ocean water (continentalcontinents, get it?).
