WebThis evidence was discovered by geophysicist Harry Hess in the early 1960s. Magnetic anomalies are stripes of alternating polarity magnetism found on the ocean floor. These stripes provide evidence of seafloor spreading and show that the ocean floor is spreading outwards from mid-ocean ridges, with new crust being formed at the ridge and older ... WebBased on these and other observations, Hess hypothesized that mid-ocean ridges marked places where new oceanic formed and that, once formed, it was continually split apart—an idea that came to be known as seafloor spreading. In essence, Hess hypothesized that the seafloor was a vast conveyor belt for oceanic crust: the crust forms at mid ...
