WebIntroduction. seafloor spreading, theory of lithospheric evolution that holds that the ocean floors are spreading outward from vast underwater ridges. First proposed in the early 1960s by the American geologist Harry H. Hess, its major tenets gave great support to the theory of continental drift and provided a conceptual base for the ... WebNov 19, 2024 · 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.

Hess collected many pieces of evidence to support the seafloor spreading theory.
