Density of oceanic crust
Weba) Continental crust and oceanic crust have equivalent densities. b) Continental crust is thicker and denser than oceanic crust. c) Continental crust is thicker and less dense than oceanic crust. d) Continental crust is thinner and denser than oceanic crust. e) Continental crust is thinner and less dense than oceanic crust. Oceanic crust is the uppermost layer of the oceanic portion of the tectonic plates. It is composed of the upper oceanic crust, with pillow lavas and a dike complex, and the lower oceanic crust, composed of troctolite, gabbro and ultramafic cumulates. The crust overlies the rigid uppermost layer of the mantle. The crust and the rigid upper mantle layer together constitute oceanic lithosphere.
