During the 1960s, scientists were already equipped with gadgets needed to explore the depth of the ocean. Wegener's theory Wegener used geologic, fossil, and glacial evidence from opposite sides of the Atlantic Ocean to support his theory of continental drift. this reptile probably couldn't swim, so he hypothesized they lived on both continents when they were joined together. The theory of continental drift (famously argued by Alfred Wegener in 1921) did not become widely accepted until we could explain why and how the continents moved. The fossils of these organisms are found on lands that are now far apart. . Who first proposed the theory of continental drift'? Paleomagnetism led the revival of the continental drift hypothesis and its transformation into theories of Sea Floor Spreading and Plate Tectonics. For example, he said that there were geological similarities between the Appalachian Mountains in North America, and the Scottish Highlands. The theory also explained Hess's puzzling guyots.

Harry Hess (1906-1969), an American geologist and professor of geology at Princeton University, discovered seafloor spreading. Who first proposed the theory of continental drift'? According to plate tectonics, a strong convection current causes the plates, where the continents are located, to move around. The theory of continental drift was the first step toward plate tectonic theory, which became the foundation upon which modern geology is built. glacial grooves are found in the warm areas today, so it means that continent used to be near the poles. Return this module to your teacher/facilitator once you are through with it. Nevertheless, Holmes, apparently, didn't quite support Continental Drift, even towards the end of his life. With the discovery of seafloor spreading, the theory of continental drift became plausible, and today, we refer to it as the plate tectonics theory. molten magma constantly erupting C. fossil evidenceB. For slabs subducting to the west, differential rotation opposes the slab motion, squeezing the bend and making the slopes steeper. Which is not evidence of seafloor spreading?

Both his ideas and those of Wegener have been greatly modified in the light of the discovery of the magnetic stripes on the Atlantic seafloor and the actual measurement of the rate and direction of the movement of the Continents. . Ex. Tuzo said that Earth's crust, or lithosphere, was divided into large, rigid pieces called plates. Answer (1 of 2): Wegener's theory was discounted because of two factors: first, it was based on Southern Hemisphere data which was highly discounted because of the Northern Hemisphere bias of European and North American scientists; Second, Wegener did not have a mechanism (observable process) tha. Played 0 times. Electromagnetism. Geology. Section Check 1 Answer The answer is A. Continental drift is the theory that the continents have slowly moved. Alfred Wegener collected diverse pieces of evidence to support his theory, including geological "fit" and fossil evidence. As with continental drift theory, two lines of evidence supporting plate tectonics are based upon the geometric fit of the displaced continents and the similarity of rock ages and Paleozoic fossils in corresponding bands or zones in adjacent or corresponding geographic areas (e.g., between West Africa . Hess's theory that new seafloor is formed when magma is forced upward toward the surface at a mid-ocean ridge. The idea of continental drift has been subsumed into the science of plate tectonics, which studies the movement of the continents as they ride on plates of the Earth's lithosphere. Continental drift is the hypothesis that the Earth's continents have moved over geologic time relative to each other, thus appearing to have "drifted" across the ocean bed. Mesosaurus - small fresh water reptile. What discovery provided strong support for Continental Drift Theory? Based on material brought up from the ocean floor during a drilling project, he determined that rocks on the ocean floor were younger than those on the continental landmasses. One of the most important contributions to the development of plate tectonic theory was Alfred Wegener's 1915 publication of 'The origin of continents and oceans' which outlined his theory of Continental Drift. Strong support for differential rotation is provided by the asymmetry of the tilt of downgoing slabs, depending on whether the plate descends to the East or West ( Fig. the nurse w … Edit. Evidence of the theory. Answer: According to libretext, Wegener used fossil evidence to support his continental drift hypothesis. Paleomagnetism is the study of the earth's past magnetic field. Paleontological studies had already demonstrated such strong similarities between the flora and fauna of the southern continents between 300,000,000 and 150,000,000 years ago that a huge supercontinent, Pangea, had been proposed (see illustration). drilling samples of rock D. magnetic stripes B. drilling samples of rock 6. The continents don't change dramatically or move independently, but are transported by the shifting tectonic plates on which they rest. The relative movement of the continents is explained by modern theories of plate tectonics.These theories describe the processes by which lithospheric plates — of which the visible continents are a part — move over the asthenosphere (the molten, ductile, upper . the nurse should refer … An adult reports usually eating the following each day: 3 cups dairy, 2 cups fruit, 2 cups vegetables, 5 ounces grains, and 5 ounces meat.
