Interest in continental drift increased in the 1950s as knowledge of Earths geomagnetic field during the geologic past developed from the studies of the British geophysicists Stanley K. Runcorn, Patrick M.S. Several types of evidence supported Hess's theory of sea-floor spreading: eruptions of molten material, magnetic stripes in the rock of the ocean floor, and the ages of the rocks themselves. Which is an example of geological fit evidence? The fact that the seeds would have been unable to be blown or floated to these continents proves that these continents were once together. By clicking Accept All, you consent to the use of ALL the cookies. Evidence Alfred Wegener collected diverse pieces of evidence to support his theory, including geological "fit" and fossil evidence. In addition South America and Africa looked like they could fit together like puzzle pieces. Continents fit like Puzzle Pieces. Please refer to the appropriate style manual or other sources if you have any questions. Rock Correlation. What is evidence use to prove continental drift? They write new content and verify and edit content received from contributors. Wegener suggested that perhaps the rotation of the Earth caused the continents to shift towards and apart from each other. Scientists agree that continents rest on rocks called tectonic plates, which shift and move. Wegener's accumulated evidence could be most logically explained by continental drift.

As molten rock rises from the Earth, it forms new crust between the plates. 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 The continents shapes fit well together and some continents have the same fossils. He explained how the continents moved Question 9 30 seconds Q. Pangaea has not been the only supercontinent on Earth. Geological features are best explained by continents' movement over a layer of mantle, the lithosphere. In 1908 Frank B. Taylor of the United States invoked the notion of continental collision to explain the formation of some of the worlds mountain ranges. Answer 5: Fossils are formed when living organisms (plants or animals) die and become buried in dirt, sand or mud. With the development of modern science and physical proof that the Earths continents are moving, the evidence is overwhelming and it is hard to deny Wegners theory that the continents once formed a single land mass and drifted apart over a long period of geological time. While every effort has been made to follow citation style rules, there may be some discrepancies. identical rocks, mountains and structures. Today, the theory of continental drift has been replaced by the science of plate tectonics.The theory of continental drift is most associated with the scientist Alfred Wegener.In the early 20th century, Wegener published a paper explaining his theory that the continental landmasses were . Convergent boundaries can also occur between two continental plates. The following piece of evidence represents matching geologic provinces in Africa and South America. The rest of the earth was covered with one huge ocean. This perfect aligning of mountain ranges indicated that the continents were once together. Evidence from fossils glaciers and complementary coastlines helps reveal how the plates once fit together. Abundant evidence supports the major contentions of the seafloor-spreading theory. Evidence that supports the theory The Matching of Continents (Jig-Saw-Fit): The shorelines of Africa and South America facing each other match remarkably. Answer (1 of 3): Continental drift is not a theory, it is a measured fact. Another fossil that supports the hypothesis of continental drift is Glossopteris (glahs AHP tur us). 3. answer choices. 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. Plate tectonics is a scientific theory describing the large-scale motion of 7 large plates and the movements of a larger number of smaller plates of the Earth's lithosphere, over the last hundreds of millions of years. It is important to know that the following specific fossil evidence was not brought up by Wegener to support his theory. Continental drift theory was given by Alfred Wegener in 1915. 2. Oceanic ridges occur along some of the plate margins. What supports Wegeners theory of plate tectonics? Through the theory of continental drift, humans have been able to figure out how the earths crust moves and the causes of volcanoes, earthquakes, oceanic trenches, formation of mountain ranges and other geological occurrences. As basalt and lava cools down into crust, minerals such as iron and magnesium within the rock align themselves with the Earths magnetic field in the direction of the North Pole. They based their idea of continental drift on several lines of evidence: fit of the continents paleoclimate indicators truncated geologic features and fossils. For example, the continents of South America and Africa fit perfectly when brought together. While making this claim, he had a collection of evidence to support it. Volcanoes are distributed randomly on every continent. What Is N For The Following Equation In Relating Kc To Kp? It seems likely, though it is still unproven, that this breakup of a single landmass and the drifting of its fragments is merely the latest in a series of similar occurrences throughout geologic time. Continental drift describes one of the earliest ways geologists thought continents moved over time. Which statement best supports the theory of continental drift? continental drift, large-scale horizontal movements of continents relative to one another and to the ocean basins during one or more episodes of geologic time. continents look like puzzle pieces and seem to fit together. Which statement best describes the theory of continental drift in terms of evidence that the continents move and the mechanism driving their movement, The theory was supported by the evidence and included a mechanism. The second theory was that the continents had been in contact with each other millions of years ago, and had somehow drifted apart. Necessary cookies are absolutely essential for the website to function properly. Some Southern Hemisphere geologists, particularly in South Africa, responded with enthusiasm. What is the five evidence of continental drift? Wegener suggested that when the organisms were alive the lands were joined and the organisms were living side-by-side. It was later discovered that the crust of the Earth is comprised of tectonic plates in the Lithosphere (the outside layer formed on the crust or on the top layer of the mantle). What was the name of the reptile that Wegners found in both South America and Africa? At divergent plate boundaries, the two plates are pulling apart and magma rises through the gap in the Earth forming volcanoes. What are the 5 evidences of continental drift? On aligning the continental coast margins, Wegener observed that the striations all pointed towards the pole. Similar fossils were found on different continents. The causes of continental drift are perfectly explained by the plate tectonic theory.

Specific interpretations in Darwins theories of evolution pose challenges to modes of proceeding within feminist critique. Alfred Wegeners Evidence of Continental Drift Theory. Blackett, and others. 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. Over the course of this essay I will review some of the evidence that support continental drift, such as fossil records and mountain ranges. There are positive and negatives in the geographies of Africa. As magma rises it forces the crust to rise at the ridge. So, technically, the creature would not have traveled through the ocean to get to the next continent. (It doesnt.) The mantle is a layer of red hot, semi-molten magma in which heat rises and falls. Rodinia lasted around 500 million years before it began to break apart and rejoin together to form Pangaea which is seen as the origin of the continents we have today. Mountain ranges and the location of ancient climatic zones. Genetics. The shape of continental coastlines visibly matched up like pieces of the puzzle. 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. Temperature and pressure both increase with depth. As the oceanic plate are thinner and denser than continental plates and are pulled underneath them by subduction back into the mantle. Laurasia contained the land masses in the northern hemisphere such as North America, Europe and Asia. 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. Fossils of creatures and plants discovered on different continents helped to him push his case that the continents were once locked together before breaking up and drifting away.

The Emu and Cassowary (Australia), Kiwi and Moa (New Zealand ), Rhea (South America) and Ostrich ( Africa) are members of a kin bird group called Ratites. The continents were once joined in a super-continent and have moved over time. 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. Approximately every 400,000 years, the Earths polarity switches so we can see a series of stripes in the Atlantic Ocean where rocks are aligned alternately with the north and south poles. Laurasia, makes up the northern continents of today. Which of the following was not a line of evidence used to support the hypothesis of continental drift? Now, looking at the current map after drifting of the continents, Cygnognathus is situated in Africa and South America.

EVIDENCE FOR CONTINENTAL DRIFT 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. Mesosaurus are fossils originating from aquatic freshwater reptiles. 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 could not have swum across the ocean. Source: www.slideserve.com. Sea floor spreading indicates that since the continents presently move apart, previous continental drift was possible and probable as well. Ex. The southern continent consists of South America, Antarctica, Australia, India, and Africa. Alfred Wegener proposed the Continental Drift Theory in 1912. The Fossil Record. This drifting takes millions of years to complete this process. Wegner also noticed that rocks and mountain ranges across continents looked similar and were similar ages, the belt of ancient rocks of 2,000 million years ago from the Brazilian coast matches with those from western Africa he also noticed that there were similar geological sequences in eastern Canada and Scotland.
