Harry Hammond Hess (1906-1969) developed theories of plate tectonics, particularly seafloor spreading as the source of new oceanic crust.
Hess's theory became known as the theory of sea-floor spreading. This theory proposed that new oceanic crust is formed at mid-ocean ridges, then moves away from the ridges, carrying continents with it.
The theory of seafloor spreading was proposed by Harry Hess, a geologist and Navy officer, in the early 1960s. He proposed that new oceanic crust is formed at mid-ocean ridges and then spreads outward. This theory helped to explain the mechanism behind continental drift and plate tectonics.
he proposed that mid-ocean ridges were areas where the floors of oceans had split apart
