Whose work explained seafloor spreading?
Quick Answer
Harry H. Hess proposed seafloor spreading in the early 1960s. His idea helped provide the mechanism that made plate tectonics convincing.
The Full Story
Harry Hammond Hess, an American geologist and naval officer, suggested that new ocean crust forms at mid-ocean ridges and moves outward like a conveyor belt. He published his ideas in 1962, building on oceanographic observations from the Second World War era. Seafloor spreading explained why the ocean floor is relatively young and why magnetic stripes appear symmetrically on either side of ridges. It became one of the key pieces of evidence supporting plate tectonics.
Key Facts
1.Hess published the idea in 1962
2.Mid-ocean ridges are where new crust forms
3.Magnetic stripes on the seafloor support the theory
