Seafloor spreading theory of lithospheric evolution that holds that the ocean floors are spreading outward from vast underwater ridges.

What evidence supports hess s theory of seafloor spreading. A mystery solved in 1912 when alfred wegener proposed that the continents had once been joined together and had split apart the biggest weakness in his hypothesis was the lack.
