Mesosaurus fossils are found in South America and South Africa, but the reptile could only swim in fresh water. Describe how the north magnetic pole appeared to move, and how that is evidence for continental drift. A R.A.F.T. Students are to create a map of the plates and write a research paper discussing Alfred Wegener's continental drift theory, subduction and sea floor spreading, the types of boundaries, and what things are caused by the movement of these plates.

Figure 6.6: Wegener used fossil evidence to support his continental drift hypothesis. To determine the relative activity. Although the evidence was extremely strong, scientists did not yet know how continents could move, so most rejected the idea. Modern day representation of the Mesosaurus. Wegeners evidence included the fit of the continents, the distribution of ancient fossils, the placement of similar rocks and structures on the opposite sides of oceans, and indicators of ancient climate found in locations where those climates do not exist today. A discussion of some of the evidence supporting continental drift on Earth. And we know that the magnetic pole wanders, too, so the correct explanation was that both the continents and the magnetic poles move. Included: Project info and explanation, student rubric, teacher's grading reubric, This comprehensive set of lessons and activities is perfect for a high school environmental science course or earth science overview. These processes were the main geologic forces behind what Wegener recognized as continental drift. strategy, but if this is new to you, here is some extra information. Required fields are marked *. For example, 400 million years ago the European north pole was different from the North American north pole at that same time. It was the first piece of evidence that continents are embedded in something bigger. Really helpful I definitely recommend sharing this website, Your email address will not be published. Which Teeth Are Normally Considered Anodontia. Continents fit like a puzzle, climate clues, fossil clues, and rock layers or formations. Over time, these continents have broken apart and moved apart through continental drift. This concept was an important precursor to the development of the theory of plate tectonics, Continental drift would resurface after World War II when a mechanism was discovered. This unit will introduce your students to the movement of tectonic plates, the landforms created at plate boundaries, and the effect of plate movement on human populations and ecosystems. Like the other kind of dating, geologic. He used several pieces of evidence to support his theory including fossils, rocks, glacial markings, coal deposits and the fact that the continents fit together like a jigsaw puzzle. 3 Types of Faults: Normal, Reverse and Strike-Slip, Chemical Weathering: Hydrolysis, Oxidation and Acidic Reactions, Divergent Plate Tectonics: Boundaries that Pull Apart, Eurasian Plate: Tectonic Boundary and Movement. WebSome fossils provide evidence that continents were once located nearer to one another than they are today. Grades: 5 th - 8 th. This is because the process of formation for igneous and metamorphic rocks involve heat or pressure that fossils would be completely erased. If the correct explanation was that the continents had remained fixed while the north magnetic pole moved, then there had to be two separate north poles. The easiest link is between the eastern Americas and western Africa and Europe, but the rest can fit together too! 7 Major Tectonic Plates: The Worlds Largest Plate Tectonics, The first thing geologists found was that some dinosaurs were better suited for water, air, and land.

These rocks were the same type and the same age. Also, we can examine the fossils we find today on each continent and check for resemblances. Location of mountains and fossils. The movement is caused by the convection currents that roll over in the upper zone of the mantle. Wegener's idea was nearly forgotten until technological advances presented puzzling new information and gave scientists the tools to develop a mechanism for Wegeners drifting continents. Complete and balance the equation for this reaction, including the phases of each reactant and product. What are the evidences of plate movements? Wegener also looked at evidence from ancient glaciers.

What are the three possible explanations for apparent polar wander when the rocks are all on one continent? There are four types of boundaries between tectonic plates that are defined by the movement of the plates: divergent and convergent boundaries, transform fault boundaries, and plate boundary zones. He suggested that at one time, all of the continents had been united into a single super continent. Although heat from the center of the Earth is migrating to the surface everywhere, the heat is concentrated at the edges of tectonic plates. WebThe four pieces of evidence for the continental drift include continents fitting together like a puzzle, scattering ancient fossils, rocks, mountain ranges, and the old climatic zones The four pieces of evidence for the continental drift include continents fitting together like a puzzle, scattering ancient fossils, rocks, mountain ranges, and the old climatic zones' locations. Fossils of remarkably similar plants and animals have been discovered on opposite sides of the Atlantic Ocean. The last supercontinent, Pangea, formed around 310 million years ago, and started breaking up around 180 million years ago. How do scientists actually know the ages of rocks? They based their idea of continental drift on several lines of evidence: fit of the continents, paleoclimate indicators, truncated geologic features, and fossils. They renamed the phenomenon of the magnetic pole that seemed to move but actually did not apparent polar wander. What is the second evidence of continental drift theory? Error message | View complete answer on https://news.temple.edu. Currently, the field's north and south magnetic poles are very near to the Earth's north and south geographic poles. Mesosaurus reptile fossils in South America and Africa 3.Glossopteris plant fossils in South America and Africa 4.Tropical plants found in arctic 5. Rocks that were the same age and were located on the same continent pointed to the same point, but that point was not the current north magnetic pole. Now, we know they were once together because its not only that continents fit together, but the same types of rocks are on the west coast of Africa and the east coast of South America. What are the 5 evidences of continental drift? What are the 6 pieces of evidence for the theory of continental drift? Wegener supported his theory by demonstrating the biological and geological similarities between continents. How can the locations where ancient fossils are found be used as evidence for continental drift? Most of the Earths geologic activity takes place at plate boundaries. At the beginning of the age of dinosaurs (during the Triassic Period, about 230 million years ago), the continents were arranged together as a single supercontinent called Pangea. What are the four pieces of evidence for continental drift quizlet? Concept note-4: WebConcept note-1: -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. Cynognathus and Lystrosaurus were reptiles that lived on land. Glacial deposits, specifically till, of the same age and structure are found on many separate continents that would have been together in the continent of Pangaea.

The second piece of evidence of Continental Drift is that the fossil of. In documenting this call, the nurse begins by writing the date and time the report was given and the name of the RN taking the report.

Although Wegener's evidence was correct, most geologists at the time rejected his hypothesis of continental drift. What evidence did Wegener use to support his hypothesis?

But before Pangaea, Earths landmasses ripped apart and smashed back together to form supercontinents repeatedly. According to Wegener, all the continents formeda single continental mass (called PANGAEA) and meg ocean (called PANTHALASSA) surrounded the same.
