In 1962, who published 'The History of Ocean Basins', which outlined the theory of how tectonic plates could move, later called 'sea floor spreading'?

American geophysicist Harry Hammond Hess published the landmark paper 'History of Ocean Basins' in 1962. In this work, he proposed the groundbreaking concept of seafloor spreading, explaining how convection currents in the mantle push magma up through oceanic ridges, creating new crust and driving tectonic plate motion. Alfred Wegener, on the other hand, proposed Continental Drift earlier in 1912.
