WebAs new seafloor forms and spreads apart from the mid-ocean ridge it slowly cools over time. Older seafloor is, therefore, colder than new seafloor, and older oceanic basins deeper than new oceanic basins due to isostasy. Webocean ridges, but over millions of years of seafloor spreading, also creates entire ocean basins.
