The theory of continental drift was the first step toward plate tectonic theory, which became the foundation upon which modern geology is built. answer choices the presence of penguins at both the equator and Antarctica Evidence supporting the hypothesis. Grooves and rock deposits left by ancient glaciers are found today on different continents very close to the equator. Who first proposed the theory of continental drift'? Continental Drift DRAFT. by kbrownlchs. Answer (1 of 2): Wegener's theory was discounted because of two factors: first, it was based on Southern Hemisphere data which was highly discounted because of the Northern Hemisphere bias of European and North American scientists; Second, Wegener did not have a mechanism (observable process) tha. Continents fit like Puzzle Pieces. What discovery provided strong support for Continental Drift Theory? ivIf you encounter any difficulty in answering the tasks in this module, do not hesitate to consult your teacher or facilitator. The theory of plate tectonics (proposed by Samuel Warren Carey in 1958) proposed that the surface of the Earth is composed of large plates that float on liquid rock (magma). 1.2.2 Hypotheses Proposed for Explaining Continental Drift. This module describes how the work of Alfred Wegener, Harry Hess, and others led to our understanding of plate tectonics. Edit. Paleontological studies had already demonstrated such strong similarities between the flora and fauna of the southern continents between 300,000,000 and 150,000,000 years ago that a huge supercontinent, Pangea, had been proposed (see illustration). There are various examples of fossils found on separate continents and in no other regions. Which of the following is evidence that supports continental drift? Geologists can calculate when and where plate movements occurred over millions of years. The continental drift hypothesis states that the position of the continents on the Earth's surface has changed considerably over time. What discovery provided strong support for Continental Drift Theory? Finish the task at hand before proceeding to the next. 17 hours ago. Plate tectonics has revolutionized the way we view large features on the surface of the Earth. Who first proposed the theory of continental drift'? ; The regions that hold the unique record of earth's magnetic field lie along the mid-ocean ridges where the sea floor is spreading. Edit. According to plate tectonics, a strong convection current causes the plates, where the continents are located, to move around. 4. According to National Geographic, sea floor spreading and plate tectonics indicate that the continents do move or shift, which supports continental drift theory. Glossopteris - plant remains found in South America, Australia, Asia and Africa. . What discovery provided strong support for Continental Drift? OVERVIEW Continental drift, in the context of the modern theory of plate tectonics, is explained by the movement of lithospheric plates over the asthenosphere (the molten, ductile, upper portion of the Earth's mantle). . Both his ideas and those of Wegener have been greatly modified in the light of the discovery of the magnetic stripes on the Atlantic seafloor and the actual measurement of the rate and direction of the movement of the Continents. The continents don't change dramatically or move independently, but are transported by the shifting tectonic plates on which they rest. While Wegener was alive, scientists did not believe that the continents could move. After going through this module, you are expected to enumerate the lines of evidence that support the plate movement (S9ES - Ia-j-36.6). 5. Seafloor spreading is a process that would help explain how the continental drift might occur. It explains plate tectonics as the driving force behind ongoing changes on Earth.

As indicated earlier, although a broad array of evidence provided by Wegener and his predecessors gave a strong indication of Wegener's far . 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. drilling samples of rock D. magnetic stripes B. drilling samples of rock 6. A. Fossils - certain fossils preserved in rocks of the same age but from different continents. Which is not evidence of seafloor spreading? glacial grooves are found in the warm areas because there was an ice age and continents . What does the theory of continental drift state? Ex. The continental drift controversy has been deeply analysed in terms of rationalist notions, which seem to find there a unique topic to describe the weight of evidence for reaching consensus. by kbrownlchs. It may help you to recall this term if you remember that it is the combination of two words: 'paleo,' which means ancient, and . Paleomagnetism has provided very strong . Formation of Pangaea. The continental drift hypothesis was developed in the early part of the 20 th century, mostly by Alfred Wegener. Return this module to your teacher/facilitator once you are through with it. Animal species that are present (today and in the past) that both come from the same common a. All of these facts supported Wegener's theory of "continental drift." In 1915 the first edition of The Origin of Continents and Oceans, a book outlining Wegener's theory, was published; expanded editions were published in 1920, 1922, and 1929. These questions ignited our scientists' curiosity to look for answers and lead to the development of the following ideas: Continental Drift Theory, Seafloor Spreading, and Earth's Magnetic Reversal. The magnets point north when Earth's magnetic field has the nurse should refer An adult reports usually eating the following each day: 3 cups dairy, 2 cups fruit, 2 cups vegetables, 5 ounces grains, and 5 ounces meat. What discovery provided strong support for Continental Drift Theory? 6.

Played 0 times. Precisely used, the term "continental drift" is actually rooted in antiquated concepts regarding the structure of the Earth. Wegener said that continents move around on Earth's surface and that they were once joined together as a single supercontinent. Paleomagnetism has provided very strong quantitative evidence for polar wander and continental drift. What discovery provided strong support for Continental Drift Theory? Mesosaurus - small fresh water reptile. Nevertheless, Holmes, apparently, didn't quite support Continental Drift, even towards the end of his life. They are always pushed.

After going through this module, you are expected to enumerate the lines of evidence that support the plate movement (S9ES - Ia-j-36.6). Harry Hess (1906-1969), an American geologist and professor of geology at Princeton University, discovered seafloor spreading. 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. answer choices The continents were once joined in a super-continent and have moved over time Continents are stationary and do not move The Earth is broken into lithospheric plates that move due to convection currents Preview this quiz on Quizizz. Based on material brought up from the ocean floor during a drilling project, he determined that rocks on the ocean floor were younger than those on the continental landmasses. These plates "float" atop an underlying rock layer called the asthenosphere. 3. In that sense, many authors suggest that Alfred Wegener's theory of the original supercontinent Pangea and the subsequent continental displacements finally reached a consensus when irrefutable evidence . Supporting Wegener's theory of continental drift, Hess explained how the once-joined continents had separated into the seven that exist today. He believed in many of the observations Wegener used in defending his theory of continental drift, but he had very different views about large-scale movements of the Earth. These questions ignited our scientists' curiosity to look for answers and lead to the development of the following ideas: Continental Drift Theory, Seafloor Spreading, and Earth's Magnetic Reversal. About 300 million years ago, claimed Wegener, the continents had formed a single mass, called Pangaea . Answer: According to libretext, Wegener used fossil evidence to support his continental drift hypothesis. 1. Earth's internal processes were previously thought to operate in a vertical fashion, with continents, oceans, and mountain ranges bobbing up and down, without much sideways movement. In 1965, a Canadian geophysicist, J. Tuzo Wilson, combined the continental drift and seafloor spreading hypotheses to propose the theory of plate tectonics. This diagnostic sequence consists of glacial deposits called tillites, followed by sandstones and finally coal measures, typical of warm moist climates. 39 Votes) Paleomagnetism is the study of the ancient magnetic field of both rocks and the Earth as a whole. Strong support for differential rotation is provided by the asymmetry of the tilt of downgoing slabs, depending on whether the plate descends to the East or West ( Fig. Pangaea splits. A. Geology C. Electromagnetism B. Fossil evidence D. Paleomagnetism 5. 0% average accuracy. 0 times. "What evidence is there to support Alfred Wegener's theory of continental drift?" Alfred Wegener, born November 1st 1880, was a German scientist who took a great interest in meteorology and paleoclimatology and in 1905 graduated from the University of Berlin with a Ph.D. in Astronomy.His most notable work was the theory of continental drift. The strikingly similar Paleozoic sedimentary sequences on all southern continents and also in India are an example of evidence that supports continental drift. Edit. 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.
