Quick Answer
Harry Hess is credited with proposing seafloor spreading in the early 1960s. He argued that new ocean crust forms at mid-ocean ridges and moves outward.
The Full Story
American geologist and naval officer Harry Hess proposed the idea of seafloor spreading in 1962. He suggested that magma rises at mid-ocean ridges, cools to form new ocean crust, and pushes older crust away. This helped explain why the ocean floor is youngest near ridges and older farther away. Hess's idea was crucial evidence leading to the acceptance of plate tectonics.
