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. 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 first truly detailed and comprehensive theory of continental drift was proposed in 1912 by Alfred Wegener, a German meteorologist. 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. 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.

One of the strongest pieces of evidence is Continental break up/fit, this is the idea that the continents were once joined together. Continental drift is defined as the motion of the earth's continents over a defined period of time. When this occurs, the sea floor grows wider, pushing the two continents apart. Answer (1 of 3): Continental drift is not a theory, it is a measured fact. The second theory was that the continents had been in contact with each other millions of years ago, and had somehow drifted apart. Alfred Wegener proposed that the continents were once united into a single supercontinent named Pangaea, meaning all earth in ancient Greek. Another evidence that supports the theory of continental drift is Paeomagnetism. Evidence for Continental Drift. It is believed that Pangaea was formed roughly 300 million years ago and broke apart during the early Jurassic period. Which of the following was not a line of evidence used to support the hypothesis of continental drift? Today we know that the continents rest on massive slabs of rock called tectonic plates. Some of the fossil evidence discovered on the continents includes mesosaurus, lystosaurus, cygnognathus and glossopteris. For example, if you take the mountains ranges of North America and Europe, they align perfectly well. 1 What evidence supports the continental drift theory?

Continents fit like a puzzle, climate clues, fossil clues, and rock layers or formations. . The theory of continental drift was supported by the theory of plate tectonics, which has been explained elaborately in Section 6. The idea of a large-scale displacement of continents has a long history. Together these discoveries supported the existence of Pangea. It also extends to a depth of 2900km. On the basis of all these factors, it may be assumed that the Americas were joined with Europe and Africa until approximately 190 million years ago, when a rift split them apart along what is now the crest of the Mid-Atlantic Ridge. What did Alfred Wegener's theory of continental . The earths outer shell is composed of plates that move a little bit every year. What are some examples of how providers can receive incentives? space and science. An example of this is the earliest known reptile, the mesosaurus. 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. This theory has explained the origin of continents and ocean basins. He proposed that the continents were not stationary, but actually moving or drifting away from one another. This indicates that the continents were once fixed together and drifted apart over time. Oceanic plates are thinner and found under the ocean, they are denser (3.0kgm) than continental plates and consist of basaltic rock. Other fossil evidence also supports the theory of continental drift. How does this document help us answer the question: A belt of ancient rocks along the Brazilian coast, for example, matches one in West Africa. South America and Africa contain fossils of animals found only on those two continents, with corresponding geographic ranges. Because Wegener could not identify a mechanism capable of moving continents.

The technical storage or access that is used exclusively for anonymous statistical purposes. Geological fit evidence is the matching of large-scale geological features on different continents. 3. Wegener's accumulated evidence could be most logically explained by 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. What evidence indicated scientists that the continents were once connected? What are the four pieces of evidence for Pangaea? To support his theory, Wegener pointed to matching rock formations and similar fossils in Brazil and West Africa. 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. The ocean floor is thus pushed at right angles and in opposite directions away from the crests. Apparent Fit. Whilst the theory that the continents had moved over time had been speculated upon before, the theory wasnt properly developed until 1912. 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. Observable evolution on small timescales. Temperature and pressure both increase with depth. Wegener specifically used rock composition and mountain ranges to provide evidence of continental drift. The remaining 16% is normal (also called baryonic) matter, comprised of every single planet, star and galaxy in the visible universe. Abundant evidence supports the major contentions of the seafloor-spreading theory. So, technically, the creature would not have traveled through the ocean to get to the next continent. 2. Genetics. 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: The movement of continents across the ocean bed is known as continental drift. His ideas attracted much attention in the 1920s and generated much controversy. Which fossil clues support the continental drift hypothesis? How is sea floor spreading related to continental drift? The Fossil Record. Molten rock material from Earths mantle rises upward to the crests, cools, and is later pushed aside by new intrusions. Similar fossils were found on different continents. The hypothesis addresses how the continents and oceans are distributed. Evidence supporting the continental drift theory. What evidence supports the idea that all the continents were once joined together? Mesosaurus - small fresh water reptile. 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. From jungles to desserts, and colonialism to urbanization. However, he supported his theory by explaining the earth's geologic history. Sea floor spreading further supports the continental drift theory. According to the modern day map, these continents are far apart. Cygnognathus is Fossil from another species of reptile. The present continents appear to fit together as pieces of a larger landmass. Which of the following statements best describes the theory of continental drift? Wegener also provided evidence of continental drift by looking at the physical shape of continental coastlines. Fossils of identical organisms were found on several continents indicating the continents were once joined. As molten rock rises from the Earth, it forms new crust between the plates. 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. (It doesnt.) Oceanic ridges occur along some of the plate margins. He knew that plant and animal fossils as well as rock layers matched up in South America and Africa. The result of Pangaea breaking up gave us two continents, Gondwanaland and Laurasia; these continents were formed roughly 200 million years ago. The rest of the earth was covered with one huge ocean. However, you may visit "Cookie Settings" to provide a controlled consent. What pieces of evidence were used to support continental drift?

So, the fact that these organisms could not swim through the vast water bodies helps to substantiate the fact that the continents were once together to allow distribution of these organisms in various continents where their fossils were found on. Plate Tectonics Theory of Continental Drift The continental drift hypothesis was developed in the early part of the 20th century, mostly by Alfred Wegener. He provided evidence that mountain ranges occurring on opposite continents matched up pretty well when brought together. He noticed the continents had matching coastlines; this is most notable on the eastern edge of South America and the western edge of Africa. Africa has some of the greatest history, and physical geography. answer choices True For millions of years, all the land of Earth was joined together in a supercontinent, which is known as Pangaea. Volcanoes are distributed randomly on every continent. Glossopteris - plant remains found in South America, Australia, Asia and Africa. Wegeners theory of continental drift states that the existing continents of the earth were once glued together forming a super landmass. What are 4 pieces of evidence that support the theory of continental drift? 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. They based their idea of continental drift on several lines of evidence: fit of the continents, paleoclimate indicators, truncated geologic features, and fossils. could scientists produce the hard evidence to support Holmes's fundamental concept. Q. 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. The force of subduction can cause volcanoes to erupt and earthquakes to occur around the subduction zone. They based their idea of continental drift on several lines of evidence: fit of the continents, paleoclimate indicators, truncated geologic features, and fossils. The general response to Wegener's hypothesis, however, was disbelief. This theory was met with skepticism and was largely dismissed by the scientific community for many years. What other evidence did Wegener need in order to convince scientists that his theory of continental drift was correct? He suggested that Pangaea broke up long ago and that the continents then moved to their current positions. What is the five evidence of continental drift? One of the clues he used was the glacier. They based their idea of continental drift on several lines of evidence: fit of the continents paleoclimate indicators truncated geologic features and fossils. 2023 EduBirdie.com. 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. Wegener supported his theory by demonstrating the biological and geological similarities between continents. Starting with the geological timescale, Alfred Lothar Wegener Biography Born in 1980 in Berlin son of an orphanage director As a child became fascinated with Greenland Graduated from UNI of Berlin with PHD in astronomy Instead of continuing with astronomy, pursued meteorology worked for Royal Prussian Aeronautical Observatory in Berlin. What are 4 evidences that support continental drift? Indications of widespread glaciation from 380 to 250 million years ago are evident in Antarctica, southern South America, southern Africa, India, and Australia. In addition, South America and Africa looked like they could fit together like puzzle pieces. This is most dramatically seen between North America and Africa during Pangeas initial rift some 240 million years ago. Answer 5: Fossils are formed when living organisms (plants or animals) die and become buried in dirt, sand or mud. Darwins finches from the Galapagos Islands. Ultimately, Africa has a beautiful context of life and history behind its luscious trees. What evidence did Wegener have for his theory of continental drift? However, would you believe if someone told you that these broken land masses were once connected to each other as one huge supercontinent?
