The ocean basins are the result of tectonic forces and processes. Earth's rocky outer crust comes in two varieties, continental andoceanic, that have very different properties and compositions. More specifically, it is a saucer-shaped depression under sea level, allowing the seawater to flow into it.It is bordered by continental margins, which extend seaward in varying degrees of inclination; this inclination determines the amount of water flowing into the basins. Geologically, there are other undersea geomorphological features such as the continental shelves, the deep ocean trenches, and the undersea mountain ranges (for example, the Mid-Atlantic Ridge and the Emperor Seamounts) which are not considered to be part of the ocean basins; while hydrologically, oceanic basins include the flanking continental shelves and the shallow epeiric seas. These in turn determine the history of seafloor spreading and subduction, driving the time dependence of the age-area distribution of ocean floor. Major basins
