On the basis of Tharps efforts and other new discoveries about the deep-ocean floor Hess postulated that molten material from Earths mantle continuously wells up along the crests of the mid-ocean ridges that wind for nearly 80000 km 50000 miles through all the worlds oceans.

There is a recycling process involved with Seafloor Spreading which is as molten rock comes up from inside earth there is much older sea floor being pushed into a ocean trench and being melted.
Eventually destroyed by subduction into an ocean trench. Prev Article Next Article. Harry Hess a professor of geology at Princeton University wrote a paper suggesting that some oceanic margins had been overridden by continents the ocean sediments at those margins were pulled down and the ocean floor was welded to the continent. Hess who served for years as the head of Princetons Geology Department died in 1969.
