The seafloor spreading hypothesis
WebDec 16, 2024 · The concept of Sea Floor Spreading Harry Hess proposed the idea of See Floor Spreading. When oceanic plates diverge, tensional stress causes fractures to occur in the lithosphere. Basaltic magma rises from the fractures and cools on the ocean floor to form new seafloor. WebHess theorized that the ocean floor is at most only a few hundred million years old, significantly younger than the continents. This is how long it takes for molten rock to ooze …
