Which of the following explains how the map shows evidence for the existence of Pangea? There are positive and negatives in the geographies of Africa. Dark Matter earned its name because it does not interact at all with the Electromagnetic Force. In support of the continental drift theory, it was established that South Africa, India, Australia and South America all experienced glaciations at the same time. One evidence of this is the existence of the same animals and plants on the different continents. These cookies ensure basic functionalities and security features of the website, anonymously. By the late 1960s, several American investigators, among them Jack E. Oliver and Bryan L. Isacks, had integrated this notion of seafloor spreading with that of drifting continents and formulated the basis of plate tectonic theory. What was never proposed as evidence supporting the existence of Pangaea? Mesosaurus was a swimming reptile but could only swim in fresh water. In the 1900's, Alfred Wegener presented an argument supporting continental drift. Fossils of identical organisms were found on several continents indicating the continents were once joined. Sea floor spreading indicates that since the continents presently move apart, previous continental drift was possible and probable as well. We are here 24/7 to write your paper in as fast as 3 hours. However, these different paths are reconciled by joining the continents in the manner proposed by Wegener. Omissions? Paleontologists refer to the total of Earths dynamic as TECO events. What do you think is meant by the line, Indelible is the stain which will forever dar 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. ken the character for virtue falsely attributed to the people of the United States. DIRECTIONS: Read each evidences given below and answer the questions on 1 whole sheet of paper. Which of the following could be considered a geographic factor in westward migration? Darwins finches from the Galapagos Islands. Another term for subduction is slab pull which suggests that as the denser oceanic plate is subducted at a convergent margin, they become denser than the underlying mantle and pulls the rest of the plate behind it. As we travel further from the mid Atlantic ridge we can see the alignment changing which proves the continents have been moving away from each other. Select three. The general response to Wegener's hypothesis, however, was disbelief. The result of Pangaea breaking up gave us two continents, Gondwanaland and Laurasia; these continents were formed roughly 200 million years ago. (askinglot.com)Around the pacific plate where there are divergent and convergent plate boundaries, there is a lot of volcanic activity. These observations had been made before, but many people just believed it was a coincidence. Another indication of continental drift is tectonic activity and seafloor spreading. (It doesnt.) answer choices. 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. To support his theory, Wegener pointed to matching rock formations and similar fossils in Brazil and West Africa. none of the above. The Earth is broken into lithospheric plates that move due to convection currents. . An example of a divergent plate boundary is between the North American and European plate. 2. To provide the best experiences, we use technologies like cookies to store and/or access device information. If you look at the map before the continents drifted away, you find that Cygnognathus was situated in South America and Africa. Evidence of Continental Drift. Again, for this creature to swim from Africa to Antarctica would have been impossible. The first truly detailed and comprehensive theory of continental drift was proposed in 1912 by Alfred Wegener, a German meteorologist. Late in the Triassic Period (which lasted from approximately 251 million to 199.6 million years ago), Pangea fragmented, and the parts began to move away from one another. Theory of the Continental Drift. This concept was an important precursor to the development of the theory of plate tectonics, which incorporates it. Genetics. coal found in cold regions, glacial evidence found in warm regions. For example, fossils of Mesosaurus, a freshwater reptile, have been found both in Brazil and western Africa. Blackett, and others. They write new content and verify and edit content received from contributors. Glossopteris - plant remains found in South America, Australia, Asia and Africa. continents look like puzzle pieces and seem to fit together. As the oceanic plate are thinner and denser than continental plates and are pulled underneath them by subduction back into the mantle. Glacier grooves are the gaping trenches or landmarks carved out by movement of glacier. What other evidence did Wegener need in order to convince scientists that his theory of continental drift was correct quizlet? Which is evidence supporting the theory of continental drift? The central dogma of biology. Watch Earth's continents move, from 650 million years ago to 250 million years in the future 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. How does General Mejia refer to the annexation of Texas? He supported his theory with geological evidence. Continental drift describes one of the earliest ways geologists thought continents moved over time. Contact Us . 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 statement best supports the theory of continental drift? Sedimentary rocks examination showed a change in climates, and the only possible explanations are continental drift or movement of the poles. The main piece of evidence supporting continental drift was the fit of the continents along their edges. He called his hypothesis continental drift. What is the first lines of evidence suggesting the existence of plate tectonics? Oceanic plates are thinner and found under the ocean, they are denser (3.0kgm) than continental plates and consist of basaltic rock. Evidence for Continental Drift In 1937 Alexander L. Du Toit, a South African geologist, modified Wegeners hypothesis by suggesting two primordial continents: Laurasia in the north and Gondwana in the south. The second theory was that the continents had been in contact with each other millions of years ago, and had somehow drifted apart. However, he supported his theory by explaining the earth's geologic history. When plates drift away from each other, there is formation of new crust at divergent boundaries. Rocks of Same Age Across the Oceans: radiometric dating methods have correlated the rock formation in different continents. On the other hand, tectonic movement destroys crust during interaction of the plates. Similar rocks found on different continents. Wegener's accumulated evidence could be most logically explained by continental drift. What evidence supports the idea that all the continents were once joined together quizlet? The four pieces of evidence for the continental drift include continents fitting together like a puzzle scattering ancient fossils rocks mountain ranges and the old climatic zones locations. It was hard for Wegner to back his theory as he was unable to explain how the continents moved. Finding identical or similar fossils in areas separated by vast distances were some of the first clues that scientists used to reconstruct past plate movement. This essay wont pass a plagiarism check! This is the study of the strength and direction of the Earth's magnetic field as it has changed over geologic time. Continental plates are slightly less dense (2.6-2.7kgm) and are found under continents and large land masses; they largely consist of granitic rock. In the early part of the 20th century scientists began to put together evidence that the continents could move around on Earths surface. Some of the fossil evidence discovered on the continents includes mesosaurus, lystosaurus, cygnognathus and glossopteris. The shape of continental coastlines visibly matched up like pieces of the puzzle. After Wegener died on an arctic expedition in 1930, only a handful of loyal supporters continued to promote his ideas. Continental drift is the suggestion that over long periods of geological time, the continents of the Earth have moved apart from each other and had once formed almost one single land mass known as Pangaea. Mountain ranges and the location of ancient climatic zones. Analytical cookies are used to understand how visitors interact with the website. Continental drift is defined as the motion of the earth's continents over a defined period of time. 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. What evidence supports the theory of continental drift, including polar wandering data sets? Sea floor spreading further supports the continental drift theory. Abundant evidence supports the major contentions of the seafloor-spreading theory. What was probably the first evidence that led some to suspect the continents were once connected? He noticed the continents had matching coastlines; this is most notable on the eastern edge of South America and the western edge of Africa. Cygnognathus is Fossil from another species of reptile. We use cookies on our website to give you the most relevant experience by remembering your preferences and repeat visits. 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.

A belt of ancient rocks along the Brazilian coast, for example, matches one in West Africa. Glossopteris ferns had very heavy seeds that could not move by wind or drift on ocean currents. Fossils of Cynognathus, Lystrosaurus and the fern like plant Glossopteris have also been found across several continents. Was the United States justified in going to war with Mexico? Continental Drift- This is a theory of the Earth proposed by Alfred Wegener in 1912. Cynognathus and Lystrosaurus were land reptiles and were unable to swim. Continents are stationary and do not move. As they are the same density, they break when they collide and are forced upwards instead. 6 pieces of evidence for continental drift.

A graphic of Gondwana. Bringing together a large mass of geologic and paleontological data, Wegener postulated that throughout most of geologic time there was only one continent, which he called Pangea. The shores of Red Sea exhibits evidence of having undergone lateral displacement /Sea flow spreading This theory has explained the origin of continents and ocean basins. 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.

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. The plates continue to move apart at the speed that our fingernails grow. Evidence of glaciers in unexpected places. He used several pieces of evidence to support his theory including fossils rocks glacial markings coal deposits and the fact that the continents fit together like a jigsaw puzzle. Wegener used fossil evidence to support his continental drift hypothesis. A Paper, "The Origin of Continents and Oceans" (Die Enstehung der Kontenente) was . Studies by Runcorn of the remanent magnetism in suitable rocks of different ages from Europe produced a polar wandering curve indicating that the magnetic poles were in different places at different times. They based their idea of continental drift on several lines of evidence: fit of the continents, paleoclimate indicators, truncated geologic features, and fossils. Grooves and rock deposits left by ancient glaciers are found today on different continents very close to the equator. To support his theory Wegener pointed to matching rock formations and similar fossils in Brazil and West Africa.

It is important to know that the following specific fossil evidence was not brought up by Wegener to support his theory. Many people didn't believe him at first. Another fossil that supports the hypothesis of continental drift is Glossopteris (glahs AHP tur us). Destruction happens when one plate moves below the other at convergent boundaries. The central dogma of biology. The ocean floor is thus pushed at right angles and in opposite directions away from the crests. Alfred Wegener created the idea of continental drift and wrote The Origin of Continents and Oceans to support his idea. unique remains in distant places. Mountains created by colliding continents. The direction of their magnetization is the same as the direction of Earths magnetic field at the time and place of crystallization. When this occurs, the sea floor grows wider, pushing the two continents apart. It has been noted that the coastlines of South America and West Africa seem to match up, however more particularly the terrains of separate continents conform as well. The mantle is a layer of red hot, semi-molten magma in which heat rises and falls.
