Mountains are typically formed when two opposite land masses collide with each other triggering the rock found at the point of collision to fold or bulge upwards. 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. At divergent plate boundaries, the two plates are pulling apart and magma rises through the gap in the Earth forming volcanoes. One evidence of this is the existence of the same animals and plants on the different continents. Dark Matter accounts for 84% of all the matter in the universe. They based their idea of continental drift on several lines of evidence: fit of the continents, paleoclimate indicators, truncated geologic features, and fossils. Evidence from fossils, glaciers, and complementary coastlines helps reveal how the plates once fit together. 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. 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. Scientists did not accept Wegeners theory of continental drift. As molten rock rises from the Earth, it forms new crust between the plates. Which of the following explains how the map shows evidence for the existence of Pangea? When he brought these continents together, the glacier grooves perfectly matched up. This theory was met with skepticism and was largely dismissed by the scientific community for many years. If you continue to use this site we will assume that you are happy with it. Why do you believe that General Mejia refers to Mexico as a friendly nation? What evidence supports that the glaciers on the southern continents were once part of a single massive ice sheet? 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 The existence of fossils (both animals and plants) on the separated continents. What evidence exists to support the existence of Pangea quizlet? 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. 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. Despite being dismissed at first, the theory gained steam in the 1950s and 1960s as new data began to support the idea of continental drift. What evidence did Wegner use to support his theory of continental drift? The cookie is set by GDPR cookie consent to record the user consent for the cookies in the category "Functional". 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. Fossil records are strong evidence that the continents do drift. The theory of continental drift was supported by the theory of plate tectonics, which has been explained elaborately in Section 6. You also have the option to opt-out of these cookies. However, he supported his theory by explaining the earth's geologic history. (askinglot.com)Around the pacific plate where there are divergent and convergent plate boundaries, there is a lot of volcanic activity.

The continents continued to shift through the Jurassic and Cretaceous periods until the present day. Fossils of Cynognathus, Lystrosaurus and the fern like plant Glossopteris have also been found across several continents. Continents fit like Puzzle Pieces. The poster child of scientific theory. Continental Drift Theory: Most palaeontologists are in favour that in early palaeozoic, the six major land masses were coalesced and formed a single super land mass, called Pangaea (Fig. When plates drift away from each other, there is formation of new crust at divergent boundaries. Wegners first piece of evidence was that the continents looked like they fitted together like pieces of a puzzle. Grooves and rock deposits left by ancient glaciers are found today on different continents very close to the equator. What is the Best Piece of Evidence for Plate Tectonics? Which two pieces of fossil evidence supports the idea of continental drift? What was probably the first evidence that led some to suspect the continents were once connected? He suggested that Pangaea broke up long ago and that the continents then moved to their current positions. The Fossil Record. 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. As magma rises it forces the crust to rise at the ridge. 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. The Earth is broken into lithospheric plates that move due to convection currents. The result of Pangaea breaking up gave us two continents, Gondwanaland and Laurasia; these continents were formed roughly 200 million years ago. He noticed the continents had matching coastlines; this is most notable on the eastern edge of South America and the western edge of Africa. . Late Paleozoic sedimentary rocks often contain extensive coal seams that were used to support the existence of Pangaea. Lystrosaurus, on the other hand, was located in Africa, India, and Antarctica.

Many evidence supports the theory of continental drift. Correct answers: 1 question: In your own words, explain the scientific evidence that supports 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. He was limited by the technology of his time and more evidence to support his claim wasnt available till scientific technology improved and evidence was found of plate tectonics. The distribution of these reptiles in different continents proves that these separate land masses were once together before splitting. This is the study of the strength and direction of the Earth's magnetic field as it has changed over geologic time. 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. 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.

As a result of movement of the supercontinent, Pangaea split into two super landmasses namely Laurasia and Gondwanaland. Another important piece of evidence in the Continental Drift theory is the fossil relevance. 3. He called his hypothesis continental drift. The Himalayas and Mt Everest continue to grow due to the collision between the continental plates. Wegener found similar evidence when he discovered tropical plant fossils in the frozen region of the Arctic Circle. 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. This essay sample was donated by a student to help the academic community. Some of the fossil evidence discovered on the continents includes mesosaurus, lystosaurus, cygnognathus and glossopteris. The possibility that they might reflect true wander of the poles was discarded, because it implies separate wanderings of many magnetic poles over the same period. 3. Continental plates are 30km-70km thick whereas the thinner oceanic plates are only 5km-10km thick. . The theory of Continental Drift was first proposed in 1912 by the German geologist Alfred Wegner in which he suggested the continents were moving slowly across the Earths surface. 6 How did Alfred Wegener come up with the idea of continental drift?

Alfred Wegener proposed that the continents were once united into a single supercontinent named Pangaea, meaning all earth in ancient Greek. Which of the following was never proposed as evidence supporting the existence of Pangaea? The Wallace Line. This suggested that these continents were once together and drifted away over time. Also, fitting the Americas with the continents across the Atlantic brings together similar kinds of rocks, fossils, and geologic structures. There is variety of evidence that supports the claims that plate tectonics accounts for (1) the distribution of fossils on different continents (2) the occurrence of earthquakes and (3) continental and ocean floor features including mountains volcanoes faults and trenches. Sea floor spreading indicates that since the continents presently move apart, previous continental drift was possible and probable as well. Which does not support the theory of continental drift? 2.

Wegener found coal in Greenland and claimed that this supported his ideas about continental drift. What evidence did Wegener make use of to develop the theory of continental drift? 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. The following are the evidence of continental drift theory: The Matching of Continents: The shorelines of Africa and South America facing each other have a remarkable and unmistakable match. As lava cools on Earths surface it forms a variety of igneous rocks. He proposed that the continents were not stationary, but actually moving or drifting away from one another.

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. Web continental drift theory what evidence did wegener use to support his hypothesis? 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. However, further work showed that the polar wandering curves are different for the various continents. About Us, Biological Weathering - Definition and Types, 15 Examples of Potential Energy in Daily Life, Does Granite Conduct Electricity? His primary sources of evidence included the fit of the continents, glacial till deposits, and the apparent shifting of climatic belts over time. What evidence supports the theory of continental drift? Heat coming from the interior of the earth triggers this movement to occur through convection currents inside the mantle.

Which of the following observations about landforms best supports the theory of plate tectonics? The theory of continental drift was first proposed by Alfred Wegener in 1912. At convergent plates, oceanic and continental plates collide. 3 Which is evidence supporting the theory of continental drift? Some 50 years later, Antonio Snider-Pellegrini, a French scientist, argued that the presence of identical fossil plants in both North American and European coal deposits could be explained if the two continents had formerly been connected, a relationship otherwise difficult to account for. Around 66 million to 30 million years ago it is believed Laurasia fragmented into the continents in the northern hemisphere we know today. Alfred Wegener proposed the Continental Drift Theory in 1912. Which of the following explains how the map shows evidence for the existence of Pangaea? Wegener specifically used rock composition and mountain ranges to provide evidence of continental drift. Another evidence that supports the theory of continental drift is Paeomagnetism.

What types of fossils were used as evidence for continental drift? Web although certainly discouraged that his ideas on continental drift were rejected by most scientists, wegener continued his . Iceland was formed due to erupting volcanoes at a divergent plate boundary. This is most dramatically seen between North America and Africa during Pangeas initial rift some 240 million years ago. 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. Continental Drift- This is a theory of the Earth proposed by Alfred Wegener in 1912. Since these match up points consisted of the same kind of rock further proves that the continents were once together before breaking away and drifting. Ferromagnetic minerals such as magnetite acquire a permanent magnetization when they crystallize as constituents of igneous rock. How did the alliance system lead to World War 1? This fossil plant has been found in Africa Australia India South America and Antarctica. identical rocks, mountains and structures. The shores of Red Sea exhibits evidence of having undergone lateral displacement /Sea flow spreading One type of evidence that strongly supported the Theory of Continental Drift is the fossil record. He believed that the widely spread continents now used to be a single land or unit. The present continents appear to fit together as pieces of a larger landmass. The geomorphology textbooks focusses on the detailed processes which takes places in the weathering of rocks and the transport of debris as landforms are created and destroyed. This cookie is set by GDPR Cookie Consent plugin. This is a reptile that comes from the Early Permian of South Africa and South America. 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. What did Alfred Wegener use as evidence for his theory that the continents were once one giant land mass quizlet? The hypothesis addresses how the continents and oceans are distributed. When this occurs, the sea floor grows wider, pushing the two continents apart. What Evidence Supports The Theory Of Continental Drift? Wegener suggested that perhaps the rotation of the Earth caused the continents to shift towards and apart from each other. Wegener used fossil evidence to support his continental drift hypothesis. 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.
