WebJan 11, 2024 · Hess resurrected Wegener's continental drift hypothesis. He reviewed the mantle convection idea. He thought about the bathymetric features and the patterns of magnetic polarity on the seafloor. In 1962, Hess published a new idea that he called seafloor spreading. Hess wrote that hot magma rises up into the rift valley at the mid … WebSupporting Wegener’s theory of continental drift, Hess explained how the once-joined continents had separated into the seven that exist today. The continents don’t change dramatically or move independently, but are transported by the shifting tectonic plates on which they rest. The theory also explained Hess’s puzzling guyots. dynamic thresholding in splunk
