The ocean floor is thus pushed at right angles and in opposite directions away from the crests. The rock formations of eastern North America Western Europe and northwestern Africa were later found to have a common origin and they overlapped in time with the presence of Gondwanaland. One indication of this possibility is the appearance of the western African and eastern South American coasts, which look like two interlocking jigsaw puzzle pieces. Glossopteris - plant remains found in South America, Australia, Asia and Africa. Which means Antarctica must have had a much warmer climate at one point, supporting Wegners theory of Continental drift. Mesosaurus . Sea floor spreading further supports the continental drift theory. short answer pls, 1.

Ferromagnetic minerals such as magnetite acquire a permanent magnetization when they crystallize as constituents of igneous rock. Background on the Ground Alfred Wegener was the developer of a new theory of the earth's surface called continental drift, and he was an adept investigator, but he passed away in 1930 with his. 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. This concept was an important precursor to the development of the theory of plate tectonics, which incorporates it. Over time, the organism decays and the area it occupied is replaced with inorganic rock. This essay sample was donated by a student to help the academic community. Other examples of Fold Mountains are: The Andes, The Alps and The Rockies. 2. We will write an essay sample crafted to your needs. He called his hypothesis continental drift. 4 What is evidence use to prove continental drift? On the other hand, tectonic movement destroys crust during interaction of the plates. Set forth in 1912 by Alfred Wegener a geophysicist and meteorologist continental drift also explained why look-alike animal and plant fossils and similar rock formations are found on different continents. . All rights reserved Particles of magnetized minerals released from their parent igneous rocks by weathering may later realign themselves with the existing magnetic field at the time these particles are incorporated into sedimentary deposits. Aside from the congruency of continental shelf margins across the Atlantic, modern proponents of continental drift have amassed impressive geologic evidence to support their views. What are some of the major pieces of evidence for the theory of plate tectonics? Which piece of evidence would provide the strongest support for the hypothesis that Earths continents were once joined? Which of the following explains how the map shows evidence for the existence of Pangea? Today we know that the continents rest on massive slabs of rock called tectonic plates. Observable evolution on small timescales. Fossils of plants and animals Distinctive rock layers and mountain ranges Glacial scratches on rocks Volcanic activity along the Ring of Fire 2 See answers Advertisement AndrewCarol Ultimately, Africa has a beautiful context of life and history behind its luscious trees. He provided evidence that mountain ranges occurring on opposite continents matched up pretty well when brought together. In terms of rock composition, at locations where continents match up, the kinds of rocks on the opposite sides of the continents were of the same kind. 2022 Sept 27 [cited 2023 Mar 1]. While every effort has been made to follow citation style rules, there may be some discrepancies. Which statement best supports the theory of continental drift? Continents are stationary and do not move. In the 1900's, Alfred Wegener presented an argument supporting continental drift. What did Alfred Wegener's theory of continental . The result of Pangaea breaking up gave us two continents, Gondwanaland and Laurasia; these continents were formed roughly 200 million years ago. The Wallace Line. 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. Specific interpretations in Darwins theories of evolution pose challenges to modes of proceeding within feminist critique. Earthguide: Online Classroom Definition: Pangaea (ucsd.edu)There were also many supercontinents that existed before Pangaea such as Ur which is said to have existed 3 billion years ago, Columbia which existed 2.5 billion years ago and Rodinia which existed 1.3.-1.9 billion years ago. How is plate tectonics supported by the apparent fit of the continental coastline? What two pieces of evidence did Wegener discover that supported the idea of Pangaea quizlet? similar fossils found on different continents, This site is using cookies under cookie policy . This theory has explained the origin of continents and ocean basins. What observations about landforms best supports the theory of plate tectonics? The present continents appear to fit together as pieces of a larger landmass. As the plates pulled apart from each other millions of years ago it caused earthquakes which led to magma rising from the mantle and erupting through the crust forming the Mid Atlantic Ridge as it solidified, this is called sea floor spreading as it is an example of two oceanic plates pulling away from each other. According to the latter hypothesis, Earths surface, or lithosphere, is composed of a number of large, rigid plates that float on a soft (presumably partially molten) layer of the mantle known as the asthenosphere.

Abundant evidence supports the major contentions of the seafloor-spreading theory. What is evidence use to prove continental drift? The curves for Europe and North America, for example, are reconciled by the assumption that the latter has drifted about 30 westward relative to Europe since the Triassic Period. continents look like puzzle pieces and seem to fit together. For example, if you take the mountains ranges of North America and Europe, they align perfectly well. It is a fern that was discovered in Africa, South America, Antarctica, India, and Australia. This apparent fit is due to the fact the continents were once connected and have since moved apart in what has been called continental drift .

So, technically, the creature would not have traveled through the ocean to get to the next continent. In addition South America and Africa looked like they could fit together like puzzle pieces. Wegener found similar evidence when he discovered tropical plant fossils in the frozen region of the Arctic Circle. 3. Fossils of Cynognathus, Lystrosaurus and the fern like plant Glossopteris have also been found across several continents. Finding fossils of the Mesosaurus on the southern hemispheres of both continents is a further indication that the two continents were once together and later drifted apart. 2. 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.Aug 11 2020, Theblogy.com What Evidence Is There of the Continental Drift Theory? The Mesosaurs would not have been able to swim across the ocean due to the fact they are freshwater creatures (and the vast distance between continents), so the mesosaurs at some point must have been able to walk across the continents. So, his theory is proved by the fact that the freshwater reptiles could not swim across the ocean waters, hence, their distribution on every continent.
