The layer that is thinnest under the oceans is the crust. While it  is thinnest in those underwater regions, it is the thickest in the  regions where mountains are.
2nd line of evidence: The Age of Ocean Crust. The youngest seafloor is at mid-ocean ridge and it becomes older with increasing distance from ridge. 3rd line of evidence: The depth of the ocean crust versus the age. As ocean crust gets older, gets cooler, and more dense, it sinks further and deeper into the asthenosphere. Younger ocean crust is warmer and less dense thus ridges higher in asthenosphere. That is why old ocean crust found at deeper depths in the ocean. Thus the farther way from mid-ocean ridge the deeper the depths.
