Some of the evidence supporting the continental drift of the tectonic plates include the presence of similar animals and plant fossils on the shores of various continents, which suggest that they were once joined. As the crust rises, gravity forces it away from the margin, driving the crust. Continental drift theory was given by Alfred Wegener in 1915. Wegener specifically used rock composition and mountain ranges to provide evidence of continental drift. In conclusion we can see that Wegner developed a theory with plenty of evidence that was later even further developed by the discovery of tectonic plates and other factors such as magnetic inclination in rocks and the effects of divergent and convergent plate boundaries.

The evidence for continental drift included the fit of the continents; the distribution of ancient fossils, rocks, and mountain ranges; and the locations of ancient climatic zones. The technical storage or access that is used exclusively for anonymous statistical purposes. Alfred Wegener created the idea of continental drift and wrote The Origin of Continents and Oceans to support his idea. continents look like puzzle pieces and seem to fit together. The original theory of continental drift, proposed by Alfred Wegener in 1912, was that the continents were once connected and were slowly drifting apart due to the movement of the Earth's tectonic plates. It has affected the global climate, the worlds geographical positions and the evolution of animals. Convergent boundaries can also occur between two continental plates.

In the early part of the 20th century scientists began to put together evidence that the continents could move around on Earths surface. Continental plates are 30km-70km thick whereas the thinner oceanic plates are only 5km-10km thick. Wegeners theory of continental drift states that the existing continents of the earth were once glued together forming a super landmass. Subsequent plate movements averaging about 2 cm (0.8 inch) per year have taken the continents to their present position. Subjects . One of the first lines of evidence suggesting the existence of plate tectonics was the discovery of very similar fossils in rock masses separated by vast distances and by ocean expanses. Well, this claim was made in the 90s by Alfred Wegener, a German polar researcher, meteorologist and geophysicist who died in 1930. Wegener used fossil evidence to support his continental drift hypothesis. Many evidence supports the theory of continental drift. Noting the apparent fit of the bulge of eastern South America into the bight of Africa, the German naturalist Alexander von Humboldt theorized about 1800 that the lands bordering the Atlantic Ocean had once been joined. Wegener, in his expedition, discovered glacier grooves in all the continents. Do now: Draw a convection current and explain why this happens? See also how many pages is a 800 word essay. Destruction happens when one plate moves below the other at convergent boundaries. Continental drift is a theory originally proposed by Alfred Wegener, who believed the continents were once one large continent known as Pangaea that later separated into several continents. He proposed that the continents were not stationary, but actually moving or drifting away from one another. Westward drift of the Americas opened the Atlantic Ocean, and the Indian block drifted across the Equator to merge with Asia. (No. What evidence supports that the glaciers on the southern continents were once part of a single massive ice sheet? backlog intangible asset; west metro fire union contract. Answer 5: Fossils are formed when living organisms (plants or animals) die and become buried in dirt, sand or mud. This could be explained either by the migration of the magnetic pole itself (that is, polar wandering) or by the migration of Europe relative to a fixed pole (that is, continental drift). South America and Africa contain fossils of animals found only on those two continents, with corresponding geographic ranges. We can also see that the basaltic rock gets older the further we travel from the mid Atlantic ridge, showing that new basaltic rock is made as the magma rises from the diverging plates.

According to the modern day map, these continents are far apart. It will explore the theory of continental drift by Alfred Wagener and the more advanced and developed theory of plate tectonics and how it has affected the volcanic hotspots and also provides several predictions for the future of Australias volcanos. After Pangaea split up, Wegner believed it formed the continents of Gondwanaland and Laurasia about 200,000 years ago before continuing to split apart to form the continents we know today. Wegener supported his theory by demonstrating the biological and geological similarities between continents. ! What were some of the main problems in cities around the turn of the 20th century? In addition South America and Africa looked like they could fit together like puzzle pieces. Increased knowledge about the configuration of the ocean floor and the subsequent formulation of the concepts of seafloor spreading and plate tectonics provided further support for continental drift. If you take a look at the map before the continents drifted away, you find that Mesosaurus is located in the southern parts of Africa and North America.

Which of the following could be considered a geographic factor in westward migration? Not consenting or withdrawing consent, may adversely affect certain features and functions. This perfect aligning of mountain ranges indicated that the continents were once together. First samples of the deep ocean floor show that basaltic oceanic crust and overlying sediment become progressively younger as the mid-ocean ridge is approached and the sediment cover is thinner near the ridge.

What evidence did Wegener not support his hypothesis of continental drift? The continents shapes fit well together and some continents have the same fossils. Laurasia contained the land masses in the northern hemisphere such as North America, Europe and Asia. Not all events are good ones, especially with the rough terrain that African had to endure, but also the good that came out of it from raw materials, but also involved exploitation. . Sea floor spreading indicates that since the continents presently move apart, previous continental drift was possible and probable as well. It also extends to a depth of 2900km.
