2 fossil evidence that support plate movement

Image Dimensions: 1280 x 720 What are the 5 pieces of evidence for plate tectonics theory? Wegener supported his argument with five lines of evidence. Details. Crop of Wegner's fossil evidence for plate movement, from This Dynamic Planet teaching resources. The name literally means ‘dog jaw’. Most distributions of rocks within Earth's crust, including minerals, fossil fuels, and energy resources, are a direct result of the history of plate motions and collisions and the corresponding changes in the configurations of the continents and ocean basins. If Continental Drift had not occurred, the alternative explanations would be: Image: From This Dynamic Earth: The Story of Plate Tectonics p8. Ancient rocks on the Brazilian coast also match those found in West Africa. Thats correct :) jvethita jvethita Answer:c. Explanation: New questions in Biology. It is a very well supported theory, and while scientific debate continues about small parts or local effects, the overall concept is accepted as good as fact. Fossils tell us when and where plants and animals once existed. According to National Geographic, sea floor spreading and plate tectonics indicate that the continents do move or shift, which supports continental drift theory. Some reached 30m tall. Mesosaurus: stratigraphically occurs near the Carboniferous-Permian boundary, this was a 2 foot long aquatic reptile that is found in fresh and brackish water deposits.Fossils are found both in Brazil and South Africa. Glossopteris then experienced a relatively … In places where these plates meet, the dense, heavy sea-floor slides under, or "subducts," the lighter continental plates. Finding similarities among the fossil records on different continents provides evidence for the theory that current continents were once connected. What kind of rocks contain fossils? The history is still being written. Fossils - certain fossils preserved in rocks of the same age but from different continents. Cynognathus is an extinct mammal-like reptile. Describe 3 pieces of evidence that Wegener used to support his theory of plate tectonics. Early Evidence: Fossils and Puzzle Pieces. Which statement explains why the continental shelf should be included? Other fossil evidence also supports the theory of continental drift. Wegener supported his argument with five lines of evidence. One piece of evidence that supports the Theory of Plate tectonics is the discovery of what in both South America and Africa? Remains of Mesosaurus, a freshwater crocodile-like reptile that lived during the early Permian (between 286 and 258 million years ago), are found solely in Southern Africa and Eastern South America. b) evidence from earthquakes: They are caused by movement at plate boundaries / Fault zones. The illustration below follows the treatment of Lutgens and Tarbuck who trace the evidence for plate tectonics that comes from the study of the magnetization of minerals. Which scientist developed this theory? They had two theories for this. What were these continents and what areas of the United States were created by new crustal segments exactly. Wegener supported his argument with five lines of evidence. The giant ocean that surrounded the continent is known as what? This was taken as evidence that the magnetic poles "wandered" over the surface … It is important to know that the following specific fossil evidence was not brought up by Wegener to support his theory. 120 seconds . Ex. Today, we have a much broader set of evidence in favor of the hypothesis. Fossils on different continents are similar to fossils on continents that were once connected. Lystrosaurus - which literally means ‘shovel reptile’ - was dominant on land in the early Triassic, 250 million years ago. Later, scientists realized that the continental shelf should be included in the theory. Jigsaw Puzzle Fit Of The Continents ; Wegner noticed that the coastlines of South America and Africa fit like the pieces of a puzzle. Evidence that can support the plate tectonics theory are the age, depth of oceanic sediments, volcanic activity, geothermal gradient, gravity anomalies, paleomagnetism and seismologic evidence. What can be used to easily track the direction of plate movement? Glacier movement Matching fossils Seafloor spreading Types and ages of rocks See answer Brainly User Brainly User The answer to your question is, Seafloor spreading-Mabel <3. Fossil Evidence 3. TyTY! Evidence that supports the theory of plate tectonics includes distribution of rock formation and fossils, shapes of existing continents, ocean floor features, and seismic and volcanic activity. Fossils 3. How did fossil evidence support the theory of continental drift? Tags: Question 2 . If you're behind a web filter, please make sure that the domains *.kastatic.org and *.kasandbox.org are unblocked. - 2873905 4.2: Paleomagnetic Evidence for Plate Tectonics Last updated; Save as PDF Page ID 4486; Contributed by Paul Webb; Professor (Biology) at Roger Williams University; No headers. The continents fit together almost like puzzle pieces forming. A second piece of evidence. Details. There are many examples of fossils found on separate continents and nowhere else, suggesting the continents were once joined. There's even rock and fossil evidence supporting continental drift. Learn about the structure of the Earth, Wegener's continental drift theory, and plate tectonics with BBC Bitesize GCSE Chemistry (WJEC). Image: From This Dynamic Earth: The Story of Plate Tectonics p8. At other places, new sea floor is created from frequent volcanic eruptions. Glossopteris flora: Glossopteris itself was a seed fern.. 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. There are two types of divergent boundaries, categorized by where they occur: continental rift zones and mid-ocean ridges. Evidence for Plate Tectonics 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. It was then surmised that if these rock outcrops were identical, then they must have been together at some point. It evolved during the Early Permian (299 million years ago) and went on to become the dominant species throughout the period, not becoming extinct until the end of the Permian. Evidence from fossils, glaciers, and complementary coastlines helps reveal how the plates once fit together. Another evidence is the fossils in the coalfields of the Appalachians which are indigenous to a warm subtropical climate but are presently located in a temperate climate. The species evolved independently on separate continents – contradicting Darwin’s theory of evolution. It is important to know that the following specific fossil evidence was not brought up by Wegener to support his theory. Plate tectonics is a relatively new theory. Two fossils in particular served as good evidence for the idea that the continents were once joined but have since separated: Glossopteris and Mesosaurus. And their fossils are found in a very specific place. There are large and small plates that are part of the lithosphere of Earth. This was not a coincidence because it indicates that the two continents were once united and had since then drifted apart. Continental drift is the hypothesis that the Earth's continents have moved over geologic time relative to each other, thus appearing to have "drifted" across the ocean bed. We have a) GPS measurements at different plates. This is based on the fact that rocks of different ages show a variable magnetic field direction, evidenced by studies since the mid–nineteenth century. The fact that life on each continent is now distinct is another type of evidence. More support for continental drift came from the puzzling evidence that glaciers once existed in normally very warm areas in southern Africa, India, Australia, and Arabia. Most distributions of rocks within Earth's crust, including minerals, fossil fuels, and energy resources, are a direct result of the history of plate motions and collisions and the corresponding changes in the configurations of the continents and ocean basins. 2. Evidence for Plate Tectonics. Evidence is Considered Other Fossils Brachiosaurus Brachiosaurus fossils have been found in Colorado and Tanzania This shows North America, Africa, and Europe were once connected Brachiosaurus couldn't have swam the whole Atlantic Ocean Brachiosaurus Lystrosaurus Cynognathus Magnetic minerals in rocks can lock-in a record of the direction and intensity of the magnetic field when they form. This suggests that South America and Africa were joined during the Early Permian. This evidence shows how Earth's plates have moved great distances, collided, and spread apart throughout Earth's history. Evidence for Continental Drift: Fit of the Continents It was the amazingly good fit of the continents that first suggested the idea of continental drift. Glacier movement Matching fossils Seafloor spreading Types and ages of rocks See answer Brainly User Brainly User The answer to your question is, Seafloor spreading-Mabel <3. During the time of Pangaea most of the dry land on Earth was joined into one huch landmass that covered nearly a third of the planet's surface. Hot spots can be used to track plate movements. 4. Studies of lava flows in Europe during the 1950s and later in North America showed a change in the orientation of the magnetic field with the age of the lava. The earliest marine fossils found along the eastern coast of South America and the western coast of Africa date from about 150 to 200 million years ago, suggesting that the Atlantic Ocean did not exist prior to that time. Gondwana associated examples (classic historical geology content):. J. Tuzo Wilson. Detailed Description. Compare and contrast the push-pull model. It explores the physical, geographical, and geological evidence for the theory of continental drift and plate tectonics. This diagnostic sequence consists of glacial deposits called tillites, followed by sandstones and finally coal measures, typical of warm moist climates. Continents are continually being shaped and reshaped by competing constructive and destructive geological processes. Glossopteris is a seed plant that appeared suddenly during the Permian period and rapidly spread throughout Gondwana, the landmass which later became South America, Australia, Africa and Antarctica. The earths crust is divided into huge plates that move and interact with each other. List the evidence and describe the evidence used to support the plate tectonics theory. Rock Type and Stuctural Similarities 4. Other life dispersed to new areas as continents reconnected, oceans narrowed, or chains of … 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 … These climate anomalies could not be explained by land bridges. - Slab pull and gravitational sliding are becoming more accepted as the main factors behind the movement of the plates. Plates push against each other at convergent boundaries. This Science Object is the fifth of five Science Objects in the Plate Tectonics SciPack. Notes: (8-1 & 8-2) The Earth's surface is constantly changing. 2. 4.2: Evidence of the Movement of Continents Last updated; Save as PDF Page ID 5478; Contributed by Deline, Harris & Tefend; Professors (Paleontology & Geology) at University of West Georgia; Sourced from GALILEO Open Learning Materials; Overview; Overview. Earth's lithosphere is divided into plates that move over the mantle, changing Earth's surface. Mesosaurus: stratigraphically occurs near the Carboniferous-Permian boundary, this was a 2 foot long aquatic reptile that is found in fresh and brackish water deposits.Fossils are found both in Brazil and South Africa. Plate movements are responsible for most continental and ocean floor features and for the distribution of most rocks and minerals within Earth's crust. Evidence for Plate Tectonics. The idea that the continents appear to have been joined based on their shapes is not new. Which of the following provides evidence that supports the theory of plate tectonics? Evidence is Considered Other Fossils Brachiosaurus Brachiosaurus fossils have been found in Colorado and Tanzania This shows North America, Africa, and Europe were once connected Brachiosaurus couldn't have swam the whole Atlantic Ocean Brachiosaurus Lystrosaurus Cynognathus Remains of Mesosaurus, a freshwater crocodile-like reptile that lived during the early Permian (between 286 and 258 million years ago), are found solely in Southern Africa and Eastern South America. When the continents split, different life forms developed. The continents have moved a great deal in the history of the planet, but they carry records of where they’ve been. answer choices . One of the most important contributions to the development of plate tectonic theory was Alfred Wegener's 1915 publication of 'The origin of continents and oceans' which outlined his theory of Continental Drift. TyTY! Q. In fact. Wegener found similar evidence when he discovered tropical plant fossils in the frozen region of the Arctic Circle. Because of the fossil evidence, we know the Mesozoic Era experienced significant continental rift. Not only do Earth's tectonic plates move, but thanks to invisible patterns on the ocean floor, we also know that the magnetic poles flip! Alfred Wegener collected diverse pieces of evidence to support his theory, including geological “fit” and fossil evidence. When the continents of the southern hemisphere are re-assembled into the single land mass of Gondwanaland, the distribution of these four fossil types form linear and continuous patterns of distribution across continental boundaries. Evidence that supports the theory of plate tectonics includes distribution of rock formation and fossils, shapes of existing continents, ocean floor features, and seismic and volcanic activity. One of the most important contributions to the development of plate tectonic theory was Alfred Wegener's 1915 publication of 'The origin of continents and oceans' which outlined his theory of Continental Drift. Glossopteris flora: Glossopteris itself was a seed fern.. The speculation that continents might have 'drifted' was first put forward by Abraham Ortelius in 1596.
