After going through this module, you are expected to enumerate the lines of evidence that support the plate movement (S9ES - Ia-j-36.6). 3. 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. While Wegener was alive, scientists did not believe that the continents could move. Continental Drift DRAFT. Continents fit like Puzzle Pieces. Nevertheless, Holmes, apparently, didn't quite support Continental Drift, even towards the end of his life. . 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. Tuzo said that Earth's crust, or lithosphere, was divided into large, rigid pieces called plates. 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 . . . After going through this module, you are expected to enumerate the lines of evidence that support the plate movement (S9ES - Ia-j-36.6). There are various examples of fossils found on separate continents and in no other regions. 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. 39 Votes) Paleomagnetism is the study of the ancient magnetic field of both rocks and the Earth as a whole. Geologists can calculate when and where plate movements occurred over millions of years. 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. Edit. Which is not evidence of seafloor spreading? . OVERVIEW Continental drift, in the context of the modern theory of plate tectonics, is explained by the movement of lithospheric plates over the asthenosphere (the molten, ductile, upper portion of the Earth's mantle). The theory of continental drift was the first step toward plate tectonic theory, which became the foundation upon which modern geology is built. Plate tectonics has revolutionized the way we view large features on the surface of the Earth. The continents don't change dramatically or move independently, but are transported by the shifting tectonic plates on which they rest. Which is notevidence of seafloor spreading?A. The evidence is fairly compelling. They are always pushed. Hess's theory that new seafloor is formed when magma is forced upward toward the surface at a mid-ocean ridge. What discovery provided strong support for Continental Drift Theory? These questions ignited our scientists' curiosity to look for answers and lead to the development of the following ideas: Continental Drift Theory, Seafloor Spreading, and Earth's Magnetic Reversal. Seafloor spreading is a process that would help explain how the continental drift might occur. For example, he said that there were geological similarities between the Appalachian Mountains in North America, and the Scottish Highlands. 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). Continental Drift DRAFT. 0 times. 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. 5. Continental drift over millions of years was caused by plate tectonics. This module describes how the work of Alfred Wegener, Harry Hess, and others led to our understanding of plate tectonics. "What evidence is there to support Alfred Wegener's theory of continental drift?" Alfred Wegener, born November 1st 1880, was a German scientist who took a great interest in meteorology and paleoclimatology and in 1905 graduated from the University of Berlin with a Ph.D. in Astronomy.His most notable work was the theory of continental drift. It may help you to recall this term if you remember that it is the combination of two words: 'paleo,' which means ancient, and . 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.

Fossils of the Mesosaurus, an ancient freshwater reptile found in the southern parts of South America and Africa, also indicate that the two continents could have once been one solid continent that drifted apart, since the reptile . Wegener said that continents move around on Earth's surface and that they were once joined together as a single supercontinent. What discovery provided strong support for Continental Drift Theory? The idea of a large-scale displacement of continents has a long history. Who first proposed the theory of continental drift'? This diagnostic sequence consists of glacial deposits called tillites, followed by sandstones and finally coal measures, typical of warm moist climates. Resources. Section Check 1 Answer The answer is A. Continental drift is the theory that the continents have slowly moved. In the 1960s, these and other scientific advances confirmed at last the theory of "plate tectonics," -the source of the energy and mechanics of plate movement on the Earth's crust. Harry Hammond Hess, a professor of geology at Princeton University, was very influential in setting the stage for the emerging plate-tectonics theory in the early 1960s. 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. Who first proposed the theory of continental drift'? Observe honesty and integrity in doing the tasks and checking your answers. What discovery about the ocean floor is associated with the seafloor spreading?
