At the consumption edges of the plate, the material has thermally contracted to become dense, and it sinks under its own weight in the process of subduction at an ocean trench. Source: Internet
As cooling continued, subduction and dissolving in ocean water removed most COmain from the atmosphere but levels oscillated wildly as new surface and mantle cycles appeared. citation. Source: Internet
