Oceanic lithosphere consists mainly of mafic crust and ultramafic mantle ( peridotite) and is denser than continental lithosphere. Young oceanic lithosphere, found at mid-ocean ridges, is no thicker than the crust, but oceanic lithosphere thickens as it ages and moves away from the mid-ocean … Meer weergeven A lithosphere (from Ancient Greek λίθος (líthos) 'rocky', and σφαίρα (sphaíra) 'sphere') is the rigid, outermost rocky shell of a terrestrial planet or natural satellite.
