The current accepted theory is that the ocean pates are subducted (dive) down toward the earth's interior at the ocean trenches. A major problem with this is that there are not nearly enough trenches to take all the ocean plates. So it has been proposed that the trenches are actually a very deep, wide crack in the ocean floor filled with water and sediment and that molten rock from far below flows toward this now lighter region but forces up mountains over a batholith (a huge mass of molten magma) before it reaches the trench.

What are the 3 main regions of the ocean floor?
The three main regions of the ocean floor are the continental margins, the ocean basins, and the mid-ocean ridges. Continental margins are the shallow, submerged edges of continents. Ocean basins are the deeper areas of the ocean floor beyond the continental margins. Mid-ocean ridges are underwater mountain ranges where tectonic plates move apart and magma rises to create new oceanic crust.
