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.

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.

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.

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?
