Cynognathus and Lystrosaurus were land reptiles and were unable to swim. By Staff Writer Last Updated March 29, 2020 According to National Geographic, sea floor spreading and plate tectonics indicate that the continents do move or shift, which supports continental drift theory. There are various examples of fossils found on separate continents and in no other regions. What are some examples of how providers can receive incentives? He suggested that Pangaea broke up long ago and that the continents then moved to their current positions. Another fossil that supports the hypothesis of continental drift is Glossopteris (glahs AHP tur us). South America and Africa contain fossils of animals found only on those two continents, with corresponding geographic ranges. 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. Over the course of millions of year ago, this gradual movement caused the once combined supercontinent to separate into 7 continents you witness in the present day. According to the Lystrosaurus and Cygnognathus body anatomy, they are not designed for swimming. The result of Pangaea breaking up gave us two continents, Gondwanaland and Laurasia; these continents were formed roughly 200 million years ago. Updates? The shape of continental coastlines visibly matched up like pieces of the puzzle. The second theory was that the continents had been in contact with each other millions of years ago, and had somehow drifted apart. For example, fossils of Mesosaurus, a freshwater reptile, have been found both in Brazil and western Africa. This was based on the evidence of fossils that he gathered. A. One evidence of this is the existence of the same animals and plants on the different continents. 1. Which statement best supports the theory of continental drift? 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 National Geographic, sea floor spreading and plate tectonics indicate that the continents do move or shift, which supports 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. These cookies help provide information on metrics the number of visitors, bounce rate, traffic source, etc. Well, we do. Alfred Wegener proposed that the continents were once united into a single supercontinent named Pangaea, meaning all earth in ancient Greek. However, these different paths are reconciled by joining the continents in the manner proposed by Wegener. 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. Not consenting or withdrawing consent, may adversely affect certain features and functions. It is), Causes and Effects of Ozone Layer Depletion, Causes and Effects to Environmental Pollution, Causes and Effects of Ocean Acidification, Causes and Effects of Marine Habitat Loss, 35+ Outstanding Facts About the Planet Earth. The theory of continental drift was first proposed by Alfred Wegener in 1912. As magma rises it forces the crust to rise at the ridge. similar fossils found on different continents, This site is using cookies under cookie policy . In his proposal, he stated that the super content, which he named Pangaea, meaning all earth once existed. Embryos of four different species. Where the plates collide they form fold mountains e.g. What key evidence supports the hypothesis of continental drift? What evidence supports the theory of continental drift quizlet? Glacial deposits, specifically till, of the same age and structure are found on many separate continents that would have been together in the continent of Pangaea. Continental drift is defined as the motion of the earth's continents over a defined period of time. Wegener, in his expedition, discovered glacier grooves in all the continents. 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 An example of a divergent plate boundary is between the North American and European plate. 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. Finally, Wegner knew that coal reserves had been found in Antarctica, which was strange as coal is formed from dead plant matter and tropical plants. Lystrosaurus, on the other hand, was located in Africa, India, and Antarctica. what two pieces of evidence did wegener discover that supported the idea of Pangaea? 4. Laurasia contained the land masses in the northern hemisphere such as North America, Europe and Asia. What evidence supports that the glaciers on the southern continents were once part of a single massive ice sheet? 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). The theory provided our understanding on the landmasses that inhabit this world as well as the ocean basins. Papers provided by EduBirdie writers usually outdo students' samples. 6014 , CY. How is sea floor spreading related to continental drift? Over time the continents change position relative to one another as they move. What is the Best Piece of Evidence for Plate Tectonics? The technical storage or access is required to create user profiles to send advertising, or to track the user on a website or across several websites for similar marketing purposes. . Fossils - certain fossils preserved in rocks of the same age but from different continents. unique remains in distant places. This theory has explained the origin of continents and ocean basins. 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). How rocks fossils and climate provide evidence of continental drift? Find out everything you need to know about it here. According to the modern day map, these continents are far apart. Sea floor spreading further supports the continental drift theory. Wegener found similar evidence when he discovered tropical plant fossils in the frozen region of the Arctic Circle. (Yes. They write new content and verify and edit content received from contributors. The shores of Red Sea exhibits evidence of having undergone lateral displacement /Sea flow spreading What do you think is meant by the line, Indelible is the stain which will forever dar Essay Service Examples Science Continental Drift. If these continents were once united around the south polar region, this glaciation would become explicable as a unified sequence of events in time and space. . Post navigation PreviousPrevious post:Is Styrofoam bad for the environment? However, this theory of continental drift came to be accepted in the 90s after his death. Evidence of Continental Drift. 3. Destruction happens when one plate moves below the other at convergent boundaries. Encyclopaedia Britannica's editors oversee subject areas in which they have extensive knowledge, whether from years of experience gained by working on that content or via study for an advanced degree. Together these discoveries supported the existence of Pangea. Which means Antarctica must have had a much warmer climate at one point, supporting Wegners theory of Continental drift. We use cookies on our website to give you the most relevant experience by remembering your preferences and repeat visits. 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. 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. 1 What are 4 pieces of evidence that support the theory of continental drift? What evidence indicated scientists that the continents were once connected? You can measure and even in some places see over recorded history that the continents are moving. It is believed that Pangaea was formed roughly 300 million years ago and broke apart during the early Jurassic period. 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. 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. 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. Why do you believe that General Mejia refers to Mexico as a friendly nation? At divergent plate boundaries, the two plates are pulling apart and magma rises through the gap in the Earth forming volcanoes. Select three. (Yes. Answer (1 of 3): Continental drift is not a theory, it is a measured fact. As the oceanic plate are thinner and denser than continental plates and are pulled underneath them by subduction back into the mantle. !

(No. 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. Sea floor spreading indicates that since the continents presently move apart, previous continental drift was possible and probable as well. If you take a look at a map of the earth today, you will see the current locations of broken land masses that constitute the earth. Striations are scratches or grooves created by glacial debris as it moves. The Himalayas. This theory was met with skepticism and was largely dismissed by the scientific community for many years. Other uncategorized cookies are those that are being analyzed and have not been classified into a category as yet. 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. This is a reptile that comes from the Early Permian of South Africa and South America. Theblogy.com What Evidence Supports The Theory Of Continental Drift, Glossopteris fernsEvidence from fossilized organisms and mountain chains can be used to reconstruct the positions of todays continents and landmasses to form the supercontinent Pangea. What evidence did Alfred Wegener use for his hypothesis? There are two varieties of tectonic plates: Oceanic plates and Continental plates. One of the strongest pieces of evidence is Continental break up/fit, this is the idea that the continents were once joined together. 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. Embryology, similarity, and vestigial structures. Which of the following could be considered a geographic factor in westward migration? For example fossils of Mesosaurus a freshwater reptile have been found both in Brazil and western Africa. Similar fossils were found on different continents. Subsequent plate movements averaging about 2 cm (0.8 inch) per year have taken the continents to their present position. What are some of the major pieces of evidence for the theory of plate tectonics? Privacy Policy . What evidence supports the idea that all the continents were once joined together? Alfred Wegener proposed that the continents were once united into a single supercontinent named Pangaea, meaning all earth in ancient Greek. 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. none of the above.

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. His ideas attracted much attention in the 1920s and generated much controversy. Well, this claim was made in the 90s by Alfred Wegener, a German polar researcher, meteorologist and geophysicist who died in 1930. The central dogma of biology. answer choices True Fossils of similar types of plants and animals in rocks of a similar age have been found on the shores of different continents, suggesting that the continents were once joined. Should you have any questions regarding our The Earth is broken into lithospheric plates that move due to convection currents. Rock Correlation. A graphic of Gondwana.

On top of that, Lystrosaurus is situated in Antarctica, India, and Africa according to the modern map. Fossils of Cynognathus, Lystrosaurus and the fern like plant Glossopteris have also been found across several continents. 6 How did Alfred Wegener come up with the idea of continental drift? There are also several smaller plates such as the Scotia, Nazca and Cocos. What evidence supports the theory of ocean floor? What observations about landforms best supports the theory of plate tectonics? From jungles to desserts, and colonialism to urbanization. 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. One piece of evidence is the complementary shapes of earths coastlines. See also how many pages is a 800 word essay. 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. Continental drift theory was given by Alfred Wegener in 1915. Whilst the theory that the continents had moved over time had been speculated upon before, the theory wasnt properly developed until 1912. Source: www.slideserve.com. Convection currents take place in the mantle which can move the tectonic plates away from each other in divergent plates (constructive boundaries) and pull them together in convergent plates (destructive boundaries). Evidence from fossils glaciers and complementary coastlines helps reveal how the plates once fit together. Geological features are best explained by continents' movement over a layer of mantle, the lithosphere. The article Flight of the Kiwi will explain how large flightless birds overcame the water barriers and dispersed around the world. For example, the continents of South America and Africa fit perfectly when brought together. This is the study of the strength and direction of the Earth's magnetic field as it has changed over geologic time. Convergent boundaries can also occur between two continental plates. One type of evidence that strongly supported the Theory of Continental Drift is the fossil record. How did Alfred Wegener come up with the idea of continental drift? 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. The ocean floor is thus pushed at right angles and in opposite directions away from the crests. However, the crust is never destroyed when plates move past one another horizontally at transform boundaries. Indications of widespread glaciation from 380 to 250 million years ago are evident in Antarctica, southern South America, southern Africa, India, and Australia.

Fossils of Mesosoaurs (freshwater aquatic reptiles) have been found on the continents of Africa and South America along with fossils of plant life providing more evidence that the continents were once joined and moved apart over time. Magnetic Reversals After molten lava emerges from a volcano, it solidifies to a rock. Over time, the organism decays and the area it occupied is replaced with inorganic rock. Evidence for Continental Drift Magnetism in rocks can also be used as evidence for the continental drift. The hypothesis addresses how the continents and oceans are distributed. It is), Is Galvanized Steel Magnetic? 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. The supercontinent was surrounded by water bodies, mainly oceans, and seas. Mesosaurus - small fresh water reptile. 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. In this essay I will describe more in-depth about the Earths dynamic structure and how plate tectonics affected biotas. 2023 EduBirdie.com. The northern continent consists of Europe, North America, and Asia. 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. Glossopteris was Fossil from fern. He supported his theory with geological evidence. How does coal in Greenland support the idea of continental drift? Lystrosaurus is Fossil from land reptiles. 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. Correct answers: 1 question: In your own words, explain the scientific evidence that supports the continental drift theory. If you continue to use this site we will assume that you are happy with it. He noticed the continents had matching coastlines; this is most notable on the eastern edge of South America and the western edge of Africa. 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. coal found in cold regions, glacial evidence found in warm regions. 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. 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. The fact that the seeds would have been unable to be blown or floated to these continents proves that these continents were once together. What evidence supports the idea that all the continents were once joined together? Continents fit like a puzzle, climate clues, fossil clues, and rock layers or formations. 2 What are some of the major pieces of evidence for the theory of plate tectonics? The cookie is set by GDPR cookie consent to record the user consent for the cookies in the category "Functional". What fossil evidence supports the belief that all of these continents were once joined and known as Pangea? Temperature and pressure both increase with depth. 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. How do you fix wet condensation on walls? Fossils of identical organisms were found on several continents indicating the continents were once joined. Laurasia, makes up the northern continents of today. This essay wont pass a plagiarism check! Embryology, similarity, and vestigial structures. identical rocks, mountains and structures. Wegener used fossil evidence to support his continental drift hypothesis. Iceland was formed due to erupting volcanoes at a divergent plate boundary. What did Alfred Wegener's theory of continental . What are the 5 evidences of continental drift? They based their idea of continental drift on several lines of evidence: fit of the continents paleoclimate indicators truncated geologic features and fossils. Dark matter is an incredibly elusive force which is necessary for many modern theories that describe the movement of galaxies and effectively all of the major elements of the universe. Answer 5: Fossils are formed when living organisms (plants or animals) die and become buried in dirt, sand or mud. More evidence was needed, and it came from the Earth's magnetism. B. 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. 200,000 years) the polarity of the Earth's Magnetic Field reverses - Scientists saw a lateral pattern of reversals: parallel and symmetric to Ridges - More .

Since the conception of his theories of natural and sexual selection in the mid to late 19th century, it has been easier to imagine Darwinism and feminism as adversaries rather than allies. It suggested that those land areas had in the past been connected. Almost all plate movement occurs in boundaries which lie between different plates. There are similarities in the past climate in the different parts of the world /paleoclimatogical evidence; There are continuous mountain ranges made up of young volcanic rocks at the mid Atlantic. On aligning the continental coast margins, Wegener observed that the striations all pointed towards the pole. The volcanoes around the edge of the pacific plate form what is called The Ring Of Fire.Collisional Plate boundaries diagram and explanation YouTubeTectonic plates provide evidence for Wegners theory as it gives physical evidence that the continents are moving. Plant Fossils- all these regions were once connected and had similar climates. Some life rode on diverging plates became isolated and evolved into new species.

See also how much do zoos make a year. However, he supported his theory by explaining the earth's geologic history. 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. Wegener used fossil evidence to support his continental drift hypothesis. space and science. Wegener also provided evidence of continental drift by looking at the physical shape of continental coastlines. What are 2 important fossils used to support continental drift? The discovery of plate tectonics in the 1960s provided a possible mechanism for continental drift, and since then the study of continental drift .
