Some life rode on diverging plates became isolated and evolved into new species. Wegener used fossil evidence to support his continental drift hypothesis. Now, looking at the current map after drifting of the continents, Cygnognathus is situated in Africa and South America. How does this document help us answer the question: 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 . One of the first lines of evidence suggesting the existence of plate tectonics was the discovery of very similar fossils in rock masses separated by vast distances and by ocean expanses. 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. The earths outer shell is composed of plates that move a little bit every year. Wegener found similar evidence when he discovered tropical plant fossils in the frozen region of the Arctic Circle. What key evidence supports the hypothesis of continental drift? Genetics. As we travel further from the mid Atlantic ridge we can see the alignment changing which proves the continents have been moving away from each other. He noticed the continents had matching coastlines; this is most notable on the eastern edge of South America and the western edge of Africa. Oceanic ridges occur along some of the plate margins. Alfred Wegener proposed the Continental Drift Theory in 1912. Lived 1880 - 1930. This cookie is set by GDPR Cookie Consent plugin. Some of the fossil evidence discovered on the continents includes mesosaurus, lystosaurus, cygnognathus and glossopteris. Was the United States justified in going to war with Mexico?

South America and Africa contain fossils of animals found only on those two continents, with corresponding geographic ranges. What are the 5 evidences of continental drift? Continental drift theory deals with the distribution of the oceans and the continents. 2. answer choices He had no good evidence. . . In the early part of the 20th century scientists began to put together evidence that the continents could move around on Earths surface. It has a density of 5.6kgm at the core and a density of 3.3kgm at the Moho (the boundary between the mantle and the crust). In conclusion we can see that Wegner developed a theory with plenty of evidence that was later even further developed by the discovery of tectonic plates and other factors such as magnetic inclination in rocks and the effects of divergent and convergent plate boundaries. Another piece of evidence is that fossils of plants, animals and invertebrates have been found on separate continents. But about 200 million years ago, the land started to drift apart and broke into two pieces. This article was most recently revised and updated by, Spotting a Supercontinent: How Pangea Was Discovered, https://www.britannica.com/science/continental-drift-geology, Geosciences LibreTexts - 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. What types of fossils were used as evidence for continental drift? What Evidence Is There of the Continental Drift Theory?

What are the four pieces of evidence for continental drift quizlet? Sea floor spreading further supports the continental drift theory. Wegener used fossil evidence to support his continental drift hypothesis. Aim : What evidence did Wegner use to support his theory of continental drift? Which statement best supports the theory of continental drift? The direction of their magnetization is the same as the direction of Earths magnetic field at the time and place of crystallization. When plates drift away from each other, there is formation of new crust at divergent boundaries. For millions of years, all the land of Earth was joined together in a supercontinent, which is known as Pangaea. See also how many pages is a 800 word essay. Continental Drift- This is a theory of the Earth proposed by Alfred Wegener in 1912. Which of the following was never proposed as evidence supporting the existence of Pangaea? Which example is another piece of evidence? 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. 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. Why does Mount Everest grow each year? What evidence did Wegener have for his theory of continental drift? 2. 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. What is the Best Piece of Evidence for Plate Tectonics? What is evidence use to prove continental drift? The rest of the earth was covered with one huge ocean. If you look at the map before the continents drifted away, you find that Cygnognathus was situated in South America and Africa. What evidence supports the theory of ocean floor? Dark Matter earned its name because it does not interact at all with the Electromagnetic Force. The technical storage or access is necessary for the legitimate purpose of storing preferences that are not requested by the subscriber or user. From jungles to desserts, and colonialism to urbanization. One of the strongest pieces of evidence is Continental break up/fit, this is the idea that the continents were once joined together. Magnetism in rocks can also be used as evidence for the continental drift. Evidence of glaciers in unexpected places. Many people didn't believe him at first. The article Flight of the Kiwi will explain how large flightless birds overcame the water barriers and dispersed around the world. Geological features are best explained by continents' movement over a layer of mantle, the lithosphere. 3. He provided evidence that mountain ranges occurring on opposite continents matched up pretty well when brought together. Other examples of Fold Mountains are: The Andes, The Alps and The Rockies. Fossil evidence for Pangaea includes the presence of similar and identical species on continents that are now great distances apart. Continental plates are 30km-70km thick whereas the thinner oceanic plates are only 5km-10km thick. Embryology, similarity, and vestigial structures. What are 2 important fossils used to support continental drift? 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. It is important to know that the following specific fossil evidence was not brought up by Wegener to support his theory. 4. Glossopteris was Fossil from fern. 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. 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. For example, fossils of Mesosaurus, a freshwater reptile, have been found both in Brazil and western Africa. The cookie is used to store the user consent for the cookies in the category "Analytics". Convergent boundaries can also occur between two continental plates. What are the 6 pieces of evidence for the theory of continental drift? Mesosaurus are fossils originating from aquatic freshwater reptiles. Plate Tectonics Theory of Continental Drift The continental drift hypothesis was developed in the early part of the 20th century, mostly by Alfred Wegener. Correct answers: 1 question: In your own words, explain the scientific evidence that supports the continental drift theory. Which of the following statements best describes the theory of continental drift? 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. What evidence supports the idea that all the continents were once joined together? Wegener specifically used rock composition and mountain ranges to provide evidence of continental drift. Post navigation PreviousPrevious post:Is Styrofoam bad for the environment? This theory was met with skepticism and was largely dismissed by the scientific community for many years. 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. He supported his theory with geological evidence. Our editors will review what youve submitted and determine whether to revise the article. 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. 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. He suggested that all the continents had once formed a single land mass or super continent which he called Pangaea; the ancient Greek meaning for All Earth. Gondwanaland contained all the masses in the southern hemisphere such as Africa, Antarctica, South America and Australia. How does this document help us answer the question: 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. 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. Evidence for Continental Drift. Mesosaurus Holmes' theories have continued to be . Wegener supported his theory by demonstrating the biological and geological similarities between continents. Because Wegener could not identify a mechanism capable of moving continents. Continental drift describes one of the earliest ways geologists thought continents moved over time. Wegener's Puzzling Evidence 1. On top of that, Lystrosaurus is situated in Antarctica, India, and Africa according to the modern map. Its, therefore, impossible that the seeds of the fern were blown by wind or floated across the ocean to have that kind of population on these 5 continents. Fossils - certain fossils preserved in rocks of the same age but from different continents. It is a fern that was discovered in Africa, South America, Antarctica, India, and Australia.

What does it mean that the Bible was divinely inspired? Wegener suggested that perhaps the rotation of the Earth caused the continents to shift towards and apart from each other. Over time, the organism decays and the area it occupied is replaced with inorganic rock. Temperature and pressure both increase with depth. The present continents appear to fit together as pieces of a larger landmass. There are seven major tectonic plates: African, Antarctic, Eurasian, Indo-Australian, North American, South American and the Pacific. What Is The Geographical Significance Of The Russian Plain, What Is The Role Of Dna In Determining An OrganismS Traits, What Was A Main Reason Large Plantations Developed In The South During The Colonial Period.

It is thought that all the continents were once joined together in one super-continent, named Pangaea. Another important piece of evidence in the Continental Drift theory is the fossil relevance. This is most dramatically seen between North America and Africa during Pangeas initial rift some 240 million years ago. 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. They based their idea of continental drift on several lines of evidence: fit of the continents, paleoclimate indicators, truncated geologic features, and fossils. 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 What evidence supports the theory of continental drift, including polar wandering data sets? 1. This theory has explained the origin of continents and ocean basins. The ocean floor is thus pushed at right angles and in opposite directions away from the crests. What other evidence did Wegener need in order to convince scientists that his theory of continental drift was correct? Cygnognathus is Fossil from another species of reptile. Fossils tell us when and where plants and animals once existed. Laurasia contained the land masses in the northern hemisphere such as North America, Europe and Asia. If you look at the current map after the continents drifted away, you find that North America and Africa are far away from each other separated by the Atlantic Ocean. During the early 1960s, the American geophysicist Harry H. Hess proposed that new oceanic crust is continually generated by igneous activity at the crests of oceanic ridgessubmarine mountains that follow a sinuous course of about 65,000 km (40,000 miles) along the bottom of the major ocean basins. Was the United States justified in going to war with Mexico. Scientists agree that continents rest on rocks called tectonic plates, which shift and move. The fossils of these organisms are found on lands that are now far apart. The main concepts that help round Abstract The study of geomorphology is an academic discipline related in explaining the earths surface and to understand the processes which create and modifies landforms. He suggested that Pangaea broke up long ago and that the continents then moved to their current positions. Answer (1 of 3): Continental drift is not a theory, it is a measured fact. Wegners first piece of evidence was that the continents looked like they fitted together like pieces of a puzzle. 6014 , CY. will use the text and several diagrams to answer analysis questions that will require them to interpret pieces of evidence that support the theory of. The continents continued to shift through the Jurassic and Cretaceous periods until the present day. We are here 24/7 to write your paper in as fast as 3 hours. Select three. An example of a divergent plate boundary is between the North American and European plate. The supercontinent was surrounded by water bodies, mainly oceans, and seas. One evidence of this is the existence of the same animals and plants on the different continents. 7 Which is an example of geological fit evidence? Evidence of Continental Drift. 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. Apart from fossil evidence, Wegener used climatic clues to substantiate his facts. Today, the theory of continental drift has been replaced by the science of plate tectonics.The theory of continental drift is most associated with the scientist Alfred Wegener.In the early 20th century, Wegener published a paper explaining his theory that the continental landmasses were . Impact craters have been found both on dry land and on the ocean floor. Evidence supporting the continental drift theory.

The striations found on the southern continents all radiate from the center of the south part of Pangaea. 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. 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. The plates continue to move apart at the speed that our fingernails grow. 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. 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. continents look like puzzle pieces and seem to fit together. 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. 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. Privacy Policy . 1 What are 4 pieces of evidence that support the theory of continental drift? unique remains in distant places. The force of subduction can cause volcanoes to erupt and earthquakes to occur around the subduction zone. However, the crust is never destroyed when plates move past one another horizontally at transform boundaries. He called his hypothesis continental drift. The discovery of fossils on different continents indicated that the continents were once together before they drifted away. What evidence supports the theory of ocean floor? Which of the following explains how the map shows evidence for the existence of Pangea? 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. Alfred Wegeners Evidence of Continental Drift Theory. 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.

The cookie is set by GDPR cookie consent to record the user consent for the cookies in the category "Functional". The global inspection reveals an imbalance of areas of lands and sea and almost infinite variation of shapes which illustrates the continental and oceanic areas. Sea floor spreading indicates that since the continents presently move apart, previous continental drift was possible and probable as well. When he brought these continents together, the glacier grooves perfectly matched up. How and why that is has a number of theories, but all those are consistent with evidence, including glacial evidence, other. Ex. The northern continent consists of Europe, North America, and Asia. 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. Source: www.slideserve.com. Fossil Correlation. However, he supported his theory by explaining the earth's geologic history. What did Alfred Wegener use as evidence for his theory that the continents were once one giant land mass quizlet? Which of the following statements best describes the theory 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. 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. 3. Access to steamboat This essay sample was donated by a student to help the academic community. What is the five evidence of continental drift?

The Wallace Line. For example fossils of Mesosaurus a freshwater reptile have been found both in Brazil and western Africa. The general response to Wegener's hypothesis, however, was disbelief. Earthguide: Online Classroom Definition: Pangaea (ucsd.edu)There were also many supercontinents that existed before Pangaea such as Ur which is said to have existed 3 billion years ago, Columbia which existed 2.5 billion years ago and Rodinia which existed 1.3.-1.9 billion years ago. What evidence exists to support the existence of Pangea 3 points? 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. Oceanic plates are thinner and found under the ocean, they are denser (3.0kgm) than continental plates and consist of basaltic rock. So, technically, the creature would not have traveled through the ocean to get to the next continent. Fossils of the seed fern Glossopteris were too heavy to be carried so far by wind. As a result of movement of the supercontinent, Pangaea split into two super landmasses namely Laurasia and Gondwanaland. There are two varieties of tectonic plates: Oceanic plates and Continental plates. 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. Mountain ranges and the location of ancient climatic zones. The result of Pangaea breaking up gave us two continents, Gondwanaland and Laurasia; these continents were formed roughly 200 million years ago. Plant Fossils- all these regions were once connected and had similar climates. What does Pangaea mean in Greek? What are some of the major pieces of evidence for the theory of plate tectonics? Today we know that the continents rest on massive slabs of rock called tectonic plates. However, you may visit "Cookie Settings" to provide a controlled consent. The distribution of these reptiles in different continents proves that these separate land masses were once together before splitting. One of the clues he used was the glacier.
