what is mesosaurus in plate tectonics
⦠In all, a dozen major plates cover Earthâs surface. For example, the mesosaurus, a freshwater reptile was found Northwest part of South America and also the Southeastern part of Africa. Tectonic plates, or lithospheric plates, are constantly moving, being created, and consumed simultaneously. A middle school lesson on plate tectonics theory for grades 6-8. These tectonic plates rest upon the convecting mantle, which causes them to move. Although plate tectonics is a relatively young idea in comparison with unifying theories from other sciences (e.g., law of gravity, theory of evolution), some of the basic ... example, fossils of the reptile Mesosaurus are found in both southern Africa and South America. answer choices . Potpourri. As you have seen, this section is absolutely essential to understanding how the Earth works, why it looks the way it does, what processes have shaped and continue to shape the Earth, and the impact it has on us today. What do the arrows on the map represent? It states that pieces of the Earth's crust are moving very slowly. Africa. plate tectonics theory. Fossil remains of the Mesosaurus were found in South America and South Africa Fossil remains of the Glossopteris found throughout India, S. America, Africa, and Antarctica CRUSTAL ACTIVITY Terms to Know: Plate Tectonics, Plates, Lithosphere, Asthenosphere Convection Currents are the driving force behind plate movement Evidences of Plate Tectonics: Scratches on rocks made by _________________ in tropical locations helped support the theory of ⦠Some span thousands of kilometers (miles) on a side. A place on Earth's crust where tectonic plate boundaries collide. PLATE TECTONICS Smith and Pun â Chapter 1 2 Tectonics is the study of the origin and ... continents and fossil remains of Mesosaurus, a freshwater reptile are found in Permian-age rocks only in Brazil and South Africa. These dinosaurs roamed Earth before the two continents broke apart. 2.4 Sketch and describe the movement along a divergent plate boundary that results in the formation of new oceanic lithosphere. The map shows a region of Earth containing volcanoes and tectonic plate boundaries. Need a Hint? A. 3) The continents of South America and Africa were joined when Mesosaurus lived. 8. Plate Tectonics. What happens when an oceanic plate converges with a continental plate? Different fossils have been found to prove that parts of other continents should be together. At the edges of the plates we see the ridges and trenches that gave the first clues to Plate Tectonics. The topics include Mesosaurus, Glossopteris, and Cynognathus fossils, in addition to mountains, trenches, volcanoes, earthquake epicenters, mantle plumes, and the mid-ocean ridge system. It was proposed by a German meteorologist and geophysicist named Alfred Wegener. C. It states that the Earth's crust is solid and unbroken. The Atlantic ocean is actually getting larger as a result of this process. Mesosaurus, meaning middle lizard, is ⦠The Glossopteris Fern, Mesosaurus Rex, and coal deposits. Mesosaurus, (genus Mesosaurus), early aquatic relative of reptiles, found as fossils from the Early Permian Period (299 million to 271 million years ago) in South Africa and South America. Mesosaurus lived in freshwater lakes and ponds. What is plate tectonics? Fold a vertical sheet of paper from side to side. 19. The movements of these plates can account for noticeable geologic events such as earthquakes, volcanic eruptions, and more subtle yet sublime events, like the building of mountains. Plate tectonics can result in the connection of. HOW PLATES MOVE. 4 By studying the distribution of different types of fossils, geologists have determined that some plates have traveled great distances. The process is known as plate tectonics. 7.14). Transform faults were also added to explain movements more completely. 2) Mesosaurus came into existence on several widely separated continents at different times. D. It measured around 71 cm from its nose to the tip of its tail. Plate tectonic theory proven by Mesosaurus Fossil, E. Brazil/W. D. It states that pieces of ⦠d) Could not have lived in Salt water for long periods of time. Plate Tectonics. 2.5 Compare and contrast the three types of convergent plate boundaries and name a location where each type can be found. 300. Turn lengthwise and fold into thirds. C. Freshwater ponds and lakes were its habitat. Over time, tectonic activity changes the Earthâs surface, rearranging and reshaping its landmasses. c) Supports the theory of Continental Drift. subduction. It states that pieces of the Earth's crust are moving quickly. Additionally, fossil remains of the land-dwelling What age are the fossils of the reptile Mesosaurus found in Africa and South America that suggested that the two continents were once together? Mesosaurus was a freshwater reptile that existed on Earth about 250 million years ago. convergent boundary. The denser oceanic plate slides under the less dense continental plate. 4) The present climates at locations X and Y are similar. the sundering of mar ine envir onments, through. Plate Tectonics and Volcanoes. The Mesosaurus is a reptile like organism that lived over 265 million years ago. Initially, this was thought to be part of an expanding Earth or a mechanism for the oceanâs growth. Turns out, it just happened to live in the right place at the right time. And that made it possible to use its fossils as evidence of the biggest idea in geology: plate tectonics. Mesosaurus, meaning middle lizard, is the name of a genus of extinct aquatic animals that lived in the southern hemisphere during early Permian time. What was the first line of evidence that led early investigators to suspect that the The plates are always moving and interacting in a process called plate tectonics. Plates move at a rate of a few centimeters a year, about the same rate fingernails grow. a) It lived in a freshwater water environment. Continental crust is ⦠When two plates meet and one gets pushed under the other. 2. It would have been physiologically impossible for Mesosaurus to swim between the continents. Earthquakes. This theory unified the theory of seafloor spreading and continental drift . What is fossil evidence located on different continents. B. Bruce Heezen and Marie Tharp were the first to make a detailed map of the ocean floor, and this map revealed the mid-Atlantic Ridge, a basaltic feature, unlike the continents. D Cynognathus, mesosaurus, and lystrosaurus Plate Tectonics 3. Plate tectonics is the scientific theory explaining the movement of the earthâs crust. Movement of the plates over Earthâs surface is termed plate tectonics. The Continental Drift hypothesis paved the way for the emergence and acceptance of the plate tectonics theory. And that made it possible to use its fossils as evidence of the biggest idea in geology: plate tectonics. Plate Tectonics Make the following Foldable to help identify what you already know, what you want to know, and what you learned about plate tectonics. Mesosaurus, (genus Mesosaurus), early aquatic relative of reptiles, found as fossils from the Early Permian Period (299 million to 271 million years ago) in South Africa and South America. The spreading of the sea floor in the middle of the Atlantic Ocean as magma forces the plates to move apart. Evidence to support this comes from the fact 1. It ate small fish. Students are separated into nine small groups or pairs to research topics relating to plate tectonic theory. Plate Tectonics 3. There are four main lines of evidence in support of plate tectonics: 1.Fit of the continents South America and Africa look like they fit together at one time: This was drawn up in 1858 by Snider-Pelligrini. 32 Related Question Answers Found ... Four fossil examples include: the Mesosaurus, Cynognathus, Lystrosaurus, and Glossopteris. Alfred Wegener (1880-1930) (Figure 10.1.1) earned a PhD in astronomy at the University of Berlin in 1904, but he had always been interested in geophysics and meteorology and spent most of his academic career working in meteorology. 3. Mesosaurus? Scientists gave the ... tectonic plates move with it in different directions. What is a convergent boundary? ... What is a mesosaurus? Plate motion is driven by heat escaping from the mantle. 10.1 Alfred Wegener: The Father of Plate Tectonics Figure 10.1.1 Alfred Wegener a few years before his death in 1930. A tectonic plate (also called lithospheric plate) is a massive, irregularly shaped slab of solid rock, generally composed of both continental and oceanic lithosphere. The motion sometimes results in earthquakes, volcanoes, and mountain ranges at the plate boundaries. The continents are still moving today. 300. Written By: Mesosaurus, (genus Mesosaurus), early aquatic relative of reptiles, found as fossils from the Early Permian Period (299 million to 271 million years ago) in South Africa and South America. Mesosaurus lived in freshwater lakes and ponds. Plate tectonics is the theory that the outer rigid layer of the earth (the lithosphere) is divided into about a dozen " plates" that move across the earth's surface relative to each other, like slabs of ice on a lake (click picture below for a larger version). Unfold and cut only the layer along both folds to In the end, he was judged as having no expert opinion in any of the fields that he leaned on for support (Plate Tectonics: Continental Drift). There are a few rules that control what happens along these edges, or plate boundaries as they are called. The coastal reptile Mesosaurus and the freshwater reptile Lystrosaurus both left remains in Africa and South America. Plate Tectonics - the Cause of Earthquakes In the early 1960s, the emergence of the theory of plate tectonics started a revolution in the earth sciences. Recall that both continental landmasses and the ocean floor are part of the earthâs crust, and that the crust is broken into individual pieces called tectonic plates (Fig. Concept Checks 2.2 1. 2.6 Describe the relative motion along a transform fault boundary A single plate can be made of all oceanic lithosphere or all continental lithosphere, but nearly all plates are made of a combination of both. Wegener hypothesized that long ago, there was a supercontinent that consisted of all landmasses on Earth. View week 3 Plate Tectonic .docx from GEOLOGY 111 at Cape Fear Community College. Fossils of the same kinds of dinosaurs, Mesosaurus, have been found in South America and Africa. (Photo by: Education Images/Universal Images Group via Getty Images) The theory of plate tectonics was, at first, rejected by most scientists. Make the front edge about 1.25 cm shorter than the back edge. the end of the 19th century about 1950 about 1960 about 1970. Underwater exploration has revealed seafloor spreading. The rules of Plate Tectonics . It is widely accepted by scientists today. 2. Its body was perfect for swimming swiftly through the water. back down. Now most geologists accept that tectonic plates exist and that these tectonic plates can and do move. formerly disjunct land areas and simultaneously. 3. Plate Tectonics Exercise Background â Plate tectonics describes the Earthâs crust as being a rigid exterior, which is divided into several slabs, or âplatesâ, which are located above the convecting mantle and move through time. 1.What evidence proved that South America, Africa, India, and Australia were once covered by glaciers? 4 Plate Tectonics Wegener concluded from his ï¬ndings that the continents must move over time. 100. This fossil was found both in West Africa and eastern Brazil proving the two continents were once joined, 1968, Mesosaurus brasiliensis. As the continents moved apart, they took mesosaurus and lystrosaurus fossils with them. The theory of plate tectonics was widely accepted by _____ . These are places where two plates interact. When it was later re⦠300. What is responsible for the change in how scientists think about plate tectonics? B. What is the theory of plate tectonics? b) Fossils were found on the continents of Africa and India. Helped proved Wegner's Theory of Continental Drift. Putting It Together: Plate Tectonics. The Theory of Plate Tectonics builds on Wegenerâs Theory of Continental Drift. The constant movement of heat in the mantle leads to circular convection currents. Chapter 4 Plate tectonics. Plate size can vary greatly, from a few hundred to thousands of kilometers across; the Pacific and Antarctic Plates are among the largest. Since then, scientists have verified and refined this theory, and now have a much better understanding of how our planet has been shaped by plate-tectonic ⦠What is a mid-atlantic ridge? The name of the continent first described by Alfred Wegener was called _______________. According to plate tectonic theory, during which geologic time interval did the continents of North America and The theory of plate-tectonics, on the other hand, states that earth's surface is broken into numbers of shifting plates or slabs. Which statement is not correct about the Mesosaurus? Plate tectonic theory proof. Tectonic plates are pieces of the lithosphere and crust, which float on the asthenosphere. Mesosaurus was the odd duck (if you'll excuse the mixed species metaphor) among its fellow prehistoric reptiles of the early Permian period. Dissipation of heat from the Earthâs interior drives plate movement. divergent boundary. It would have been physiologically impossible for Mesosaurus to swim between the continents. This suggests that South America and Africa were joined during the Early Permian. Cynognathus is an extinct mammal-like reptile. The term tectonics comes from a Greek word meaning âto build.â Tectonic plates are huge moving slabs that together make up Earthâs outer layer. Plate Tectonics. In the Theory of Plate Tectonics, it is tectonic plates, rather than continents, which are moving. Starting in 1947 and using an adaptation of sonar, researchers began to map a poorly understood topographic and thermal high in the mid-Atlantic.
