Is the crust less dense than mantle

WitrynaThe continental crust is also less dense than oceanic crust, although it is considerably thicker. As a consequence of the density difference, when active margins of continental crust meet oceanic crust in subduction zones, the oceanic crust is typically subducted back into the mantle. WitrynaThe density of the crustal rocks is lower than the core and mantle because of lighter elements such as oxygen, silicon, aluminium, potassium and sodium. There is a large difference in the thickness of the crust depending on what is on the surface. It can …
