Evidence that supports the theory The Matching of Continents (Jig-Saw-Fit): The shorelines of Africa and South America facing each other match remarkably. These reptiles lived in freshwater bodies such as lakes and rivers. Wegener used fossil evidence to support his continental drift hypothesis. What pieces of evidence were used to support continental drift? (Yes. Evidence for Continental Drift 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. Answer 5: Fossils are formed when living organisms (plants or animals) die and become buried in dirt, sand or mud. Continental drift was a theory that explained how continents shift position on Earths surface. What pieces of evidence were used to support plate tectonics?

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. Magnetic Reversals After molten lava emerges from a volcano, it solidifies to a rock. At convergent plates, oceanic and continental plates collide. 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. Many people didn't believe him at first. The striations found on the southern continents all radiate from the center of the south part of Pangaea.

They based their idea of continental drift on several lines of evidence: fit of the continents, paleoclimate indicators, truncated geologic features, and fossils. The main piece of evidence supporting continental drift was the fit of the continents along their edges. Paleontologists refer to the total of Earths dynamic as TECO events. . Continental drift describes one of the earliest ways geologists thought continents moved over time. 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.

Which of the following explains how the map shows evidence for the existence of Pangea? This concept was an important precursor to the development of the theory of plate tectonics, which incorporates it. It does not store any personal data. 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 Earth's surface. The fossils of these organisms are found on lands that are now far apart. Fossil evidence for Pangaea includes the presence of similar and identical species on continents that are now great distances apart. 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. Privacy Policy 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.

It was hard for Wegner to back his theory as he was unable to explain how the continents moved. 3. However, would you believe if someone told you that these broken land masses were once connected to each other as one huge supercontinent? This perfect aligning of mountain ranges indicated that the continents were once together. One indication of this possibility is the appearance of the western African and eastern South American coasts, which look like two interlocking jigsaw puzzle pieces. Theory of the Continental Drift. 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. Continental Drift: The movement of continents across the ocean bed is known as continental drift. Dark Matter accounts for 84% of all the matter in the universe.

Embryology, similarity, and vestigial structures. Glossopteris was Fossil from fern. Alfred Wegener, in the first three decades of this century, and DuToit in the 1920s and 1930s gathered evidence that the continents had moved. 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. It also extends to a depth of 2900km. He provided evidence that mountain ranges occurring on opposite continents matched up pretty well when brought together. Another fossil that supports the hypothesis of continental drift is Glossopteris (glahs AHP tur us). The fossils of these organisms are found on lands that are now far apart.

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. This drifting takes millions of years to complete this process. fossil. What Evidence Supports The Theory Of Continental Drift? After Wegener died on an arctic expedition in 1930, only a handful of loyal supporters continued to promote his ideas. 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. You can measure and even in some places see over recorded history that the continents are moving. An example of a convergent plate boundary is the Pacific Plate and the Eurasian plate. As the crust rises, gravity forces it away from the margin, driving the crust. 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. 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.

Apart from fossil evidence, Wegener used climatic clues to substantiate his facts. A graphic of Gondwana. 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. Forces behind the drifting of continents, according to Wegener Evidence in support of Continental Drift Drawbacks of Continental Drift Theory Tectonics During WW II, it was discovered that the ocean floor had some unique relief features like ridges, trenches, seamounts, shoals etc. The Theory of Continental Drift was proposed by Alfred Wegener in 1912. 2023 EduBirdie.com. Over time the continents change position relative to one another as they move. 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. The Earth is broken into lithospheric plates that move due to convection currents. What did Alfred Wegener discover? As Wegener collected more data he realized the explanation that best fit all the climate rock and fossil observations involved moving continents. After Pangaea split up, Wegner believed it formed the continents of Gondwanaland and Laurasia about 200,000 years ago before continuing to split apart to form the continents we know today. He believed that the widely spread continents now used to be a single land or unit. What types of evidence best supports the theory of plate tectonics?

They remained in this slow phase for about 40 million years. He provided evidence that mountain ranges occurring on opposite continents matched up pretty well when brought together. When this occurs, the sea floor grows wider, pushing the two continents apart. Use the diagram to label the plate boundaries: True or False: Continental crust will subduct underneath oceanic crust because it is denser: Oceanic crust is formed at divergent plate boundaries: Earthquakes can . He suggested that Pangaea broke up long ago and that the continents then moved to their current positions. Not all events are good ones, especially with the rough terrain that African had to endure, but also the good that came out of it from raw materials, but also involved exploitation. It is thought that all the continents were once joined together in one super-continent, named Pangaea.

Which fossil clues support the continental drift hypothesis? Mountain ranges and the location of ancient climatic zones. What does the theory of continental drift state? Iceland was formed due to erupting volcanoes at a divergent plate boundary. Over time, the landmass broke and drifted away and is still drifting to this day. 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. The supercontinent was surrounded by water bodies, mainly oceans, and seas. Magnetism in rocks can also be used as evidence for the continental drift. It has affected the global climate, the worlds geographical positions and the evolution of animals. The continents were once joined in a super-continent and have moved over 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. Scientists agree that continents rest on rocks called tectonic plates, which shift and move. 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. 4 What are 5 pieces of evidence of continental drift? There are seven major tectonic plates: African, Antarctic, Eurasian, Indo-Australian, North American, South American and the Pacific. Several types of evidence supported Hess's theory of sea-floor spreading: eruptions of molten material, magnetic stripes in the rock of the ocean floor, and the ages of the rocks themselves. Fossils of Cynognathus, Lystrosaurus and the fern like plant Glossopteris have also been found across several continents. Sedimentary rocks examination showed a change in climates, and the only possible explanations are continental drift or movement of the poles. 1. To support his theory Wegener pointed to matching rock formations and similar fossils in Brazil and West Africa. The central dogma of biology. As the plates move away from the flanks of the ridges, they carry the continents with them. The idea of a large-scale displacement of continents has a long history. Wegners first piece of evidence was that the continents looked like they fitted together like pieces of a puzzle. However, further work showed that the polar wandering curves are different for the various continents. However, this theory of continental drift came to be accepted in the 90s after his death. As they are the same density, they break when they collide and are forced upwards instead. What evidence did Alfred Wegener use for his hypothesis? Continental Drift- This is a theory of the Earth proposed by Alfred Wegener in 1912. Wegener supported his theory by demonstrating the biological and geological similarities between continents. 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). answer choices True Advertisement cookies are used to provide visitors with relevant ads and marketing campaigns. space and science.
