Seafloor spreading theory seems to explain why the ancestors of a green turtle (Chelonia mydas) subpopulation which now travels 2,000 km from Brazil to breed at Ascension Island, were induced to swim oceanwards
The seafloor spreading hypothesis was proposed by the American geophysicistHarry H. Hess in 1960. On the basis of Tharp’s efforts and other new discoveries about the deep-ocean floor, Hess postulated that molten material fromEarth’s mantlecontinuously wells up along the crests of themid-ocean ...
Who proposed the theory of seafloor spreading? Harry Hess proposed the idea of seafloor spreading in 1960. He used maps created by solar readings of the ocean floor. He explained that seafloor spreading caused these features as new crust was made. Seafloor spreading became a theory as more scie...

theory in 1912, suggesting that the continents were once all joined together in a supercontinent he called Pangaea. Wegener proposed that at some time, the land masses had drifted apart until they occupied their current positions on the globe. There was lots of evidence to support his theory ...
Introduction The revolutionary seafloor spreading hypothesis improved and subsumed the continental drift hypothesis, and rapidly culminated in what is now known as plate tectonic theory. First hypothesized by Harry Hess in 1960, in a paper (Hess, 1962) he considered so speculative he called it “an...
