WebSep 27, 2024 · Seafloor spreading is a geologic process in which tectonic plates —large slabs of Earth's lithosphere —split apart from each other. Seafloor spreading and other … WebEvidence for Seafloor Spreading. Much like Wegener before him, Hess ran into considerable resistance to his hypothesis by other geologists. There was little data from the ocean floor that could support his current hypothesis. Knowing that he still needed more data to convince the scientific community, Hess continued to work on his research. scaffolding net core

WebHarry Hess proposed the seafloor spreading hypothesis in 1960 (published in 1962); the term "spreading of the seafloor" was introduced by geophysicist Robert S. Dietz in 1961. According to Hess, seafloor was created at mid-oceanic ridges by the convection of the earth's mantle, pushing and spreading the older crust away from the ridge. ... WebMay 20, 2024 · Who were the two scientists who proposed the theory of seafloor spreading in the early 90s 80s? Heezen published the concept of mid-ocean ridges. Soon after this, Robert S. Dietz and Harry H. Hess proposed that the oceanic crust forms as the seafloor spreads apart along mid-ocean ridges in seafloor spreading. WebDec 16, 2024 · The alternating pattern of magnetic striping on the seafloor. The concept of Sea Floor Spreading. Harry Hess proposed the idea of See Floor Spreading. When oceanic plates diverge, tensional stress causes fractures to occur in the lithosphere. Basaltic magma rises from the fractures and cools on the ocean floor to form new seafloor. scaffolding netting toolstation
