The sedimentary rocks in the bottom of the oceans are younger because the ocean floor is constantly recycling itself. Oceanic plates are being added at the oceanic ridges, and being destroyed by subduction when colliding with the continental plate. The sedimentary rocks on continents are definitely subject to forces of erosion, but not in general to the plate of the destruction of the forces.
