oceanic crust is the relatively thin part of the earths crust which underlies the ocean basins. it is geologically young compared with the continental crust and consists of basaltic rock overlain by sediments
It is the solid rock layer upon which we live. It is either continental or oceanic. Continental crust is typically 30-50 km thick, whilst oceanic crust is only 5-10 km thick. Oceanic crust is denser, can be subducted and is constantly being destroyed and replaced at plate boundaries.
