B. Ferromagnetic minerals such as magnetite acquire a permanent magnetization when they crystallize as constituents of igneous rock. Sea floor spreading indicates that since the continents presently move apart, previous continental drift was possible and probable as well. 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. 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. Embryology, similarity, and vestigial structures. Dark Matter earned its name because it does not interact at all with the Electromagnetic Force.

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. 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 Earths surface. 6 pieces of evidence for continental drift. 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. Alfred Wegener created the idea of continental drift and wrote The Origin of Continents and Oceans to support his idea. So, his theory is proved by the fact that the freshwater reptiles could not swim across the ocean waters, hence, their distribution on every continent. For example, fossils of Mesosaurus, a freshwater reptile, have been found both in Brazil and western Africa. 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. 2023 EduBirdie.com. answer choices.

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. Continental drift was a theory that explained how continents shift position on Earths surface. Some 50 years later, Antonio Snider-Pellegrini, a French scientist, argued that the presence of identical fossil plants in both North American and European coal deposits could be explained if the two continents had formerly been connected, a relationship otherwise difficult to account for.

Continental Drift: The movement of continents across the ocean bed is known as 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. In support of the continental drift theory, it was established that South Africa, India, Australia and South America all experienced glaciations at the same time. However, further work showed that the polar wandering curves are different for the various continents. In the 1900's, Alfred Wegener presented an argument supporting continental drift. Ex.

Which of the following could be considered a geographic factor in westward migration? short answer pls, 1. 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. The first truly detailed and comprehensive theory of continental drift was proposed in 1912 by Alfred Wegener, a German meteorologist. Laurasia contained the land masses in the northern hemisphere such as North America, Europe and Asia.

What were some of the main problems in cities around the turn of the 20th century? Oceanic ridges occur along some of the plate margins. An example of a convergent plate boundary is the Pacific Plate and the Eurasian plate. Wegner also noticed that rocks and mountain ranges across continents looked similar and were similar ages, the belt of ancient rocks of 2,000 million years ago from the Brazilian coast matches with those from western Africa he also noticed that there were similar geological sequences in eastern Canada and Scotland. Fossils of the seed fern Glossopteris were too heavy to be carried so far by wind. (No. It is a fern that was discovered in Africa, South America, Antarctica, India, and Australia.

These reptiles lived in freshwater bodies such as lakes and rivers. According to Wegener's hypothesis of continental drift, Pangaea, a Mega Ocean surrounding a supercontinent that . 2. 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). Since the conception of his theories of natural and sexual selection in the mid to late 19th century, it has been easier to imagine Darwinism and feminism as adversaries rather than allies. It has affected the global climate, the worlds geographical positions and the evolution of animals. 2. How rocks fossils and climate provide evidence of continental drift?

The idea of a large-scale displacement of continents has a long history. What was never proposed as evidence supporting the existence of Pangaea? Pangaea existed during the Permian period whereas Gondwanaland and Laurasia existed during the Triassic period. Continental drift is a theory originally proposed by Alfred Wegener, who believed the continents were once one large continent known as Pangaea that later separated into several continents. The rest of the earth was covered with one huge ocean. What was the name of the reptile that Wegners found in both South America and Africa? 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. . What evidence did Wegener not support his hypothesis of continental drift? He knew that plant and animal fossils as well as rock layers matched up in South America and Africa. Similar rocks found on different continents. 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. Evidence of glaciers in unexpected places. We can also see that the basaltic rock gets older the further we travel from the mid Atlantic ridge, showing that new basaltic rock is made as the magma rises from the diverging plates. When he was tasked with proving how these continents moved to different places, he couldnt. 4. ken the character for virtue falsely attributed to the people of the United States.

Evidence of Continental Drift. It was hard for Wegner to back his theory as he was unable to explain how the continents moved. What is the five evidence of continental drift? According to the latter hypothesis, Earths surface, or lithosphere, is composed of a number of large, rigid plates that float on a soft (presumably partially molten) layer of the mantle known as the asthenosphere. Continental drift has impacted the universe in many ways. Continental drift also comes along with grave effects such as Volcanoes, Earthquakes, and Tsunamis. Lystrosaurus, on the other hand, was located in Africa, India, and Antarctica. 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. Apart from fossil evidence, Wegener used climatic clues to substantiate his facts. What evidence supports that the glaciers on the southern continents were once part of a single massive ice sheet? Continental drift theory was given by Alfred Wegener in 1915. Access to steamboat In 1908 Frank B. Taylor of the United States invoked the notion of continental collision to explain the formation of some of the worlds mountain ranges. Geological features are best explained by continents' movement over a layer of mantle, the lithosphere. When this occurs, the sea floor grows wider, pushing the two continents apart. Fossil evidence for Pangaea includes the presence of similar and identical species on continents that are now great distances apart. As the divergent plates move apart and new magma rises from the mantle it will record the current alignment of the North Pole. Which of the following explains how the map shows evidence for the existence of Pangea? It also extends to a depth of 2900km. Do now: Draw a convection current and explain why this happens? On top of that, Lystrosaurus is situated in Antarctica, India, and Africa according to the modern map. Convergent boundaries can also occur between two continental plates.
