Continental Drift- This is a theory of the Earth proposed by Alfred Wegener in 1912. Embryology, similarity, and vestigial structures. Fossils. Evidence for Continental Drift The distribution of these reptiles in different continents proves that these separate land masses were once together before splitting. Fossil evidence for Pangaea includes the presence of similar and identical species on continents that are now great distances apart. Evidence Supporting Continental Drift Continental Drift Theory Proposed by Alfred Wegener in 1912 250 million years ago, all of the continents were combined into one super-continent called "Pangaea" The continents gradually drifted apart to where they are today Alfred Wegener (1880-1930), German meteorologist and geologist, was the first . Corrections? Over time, the organism decays and the area it occupied is replaced with inorganic rock. . This means it does not absorb, emit or reflect visible light, gamma rays, ultra-violet rays etc. It is important to know that the following specific fossil evidence was not brought up by Wegener to support his theory. Ferromagnetic minerals such as magnetite acquire a permanent magnetization when they crystallize as constituents of igneous rock. 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. 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. The Earth is broken into lithospheric plates that move due to convection currents. On the other hand, tectonic movement destroys crust during interaction of the plates. How rocks fossils and climate provide evidence of continental drift? All rights reserved A belt of ancient rocks along the Brazilian coast, for example, matches one in West Africa. The technical storage or access is required to create user profiles to send advertising, or to track the user on a website or across several websites for similar marketing purposes.

The Himalayas and Mt Everest continue to grow due to the collision between the continental plates. What did Alfred Wegener's theory of continental . They based their idea of continental drift on several lines of evidence: fit of the continents paleoclimate indicators truncated geologic features and fossils. Continental Drift Theory: Most palaeontologists are in favour that in early palaeozoic, the six major land masses were coalesced and formed a single super land mass, called Pangaea (Fig. You can order a unique, plagiarism-free paper written by a professional writer. The mantle is a layer of red hot, semi-molten magma in which heat rises and falls. Find out everything you need to know about it here. What are the 4 pieces of evidence that support plate tectonics? Oceanic ridges occur along some of the plate margins. short answer pls, 1. . 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. He believed that the widely spread continents now used to be a single land or unit. Heat coming from the interior of the earth triggers this movement to occur through convection currents inside the mantle. Through the theory of continental drift, humans have been able to figure out how the earths crust moves and the causes of volcanoes, earthquakes, oceanic trenches, formation of mountain ranges and other geological occurrences. In the early part of the 20th century scientists began to put together evidence that the continents could move around on Earths surface. What are 2 important fossils used to support continental drift? Not all events are good ones, especially with the rough terrain that African had to endure, but also the good that came out of it from raw materials, but also involved exploitation. What are 4 pieces of evidence that support the theory of continental drift? In terms of rock composition, at locations where continents match up, the kinds of rocks on the opposite sides of the continents were of the same kind. 5. Which statement best supports the theory of continental drift? Continental drift describes one of the earliest ways geologists thought continents moved over time. 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. In this essay I will describe more in-depth about the Earths dynamic structure and how plate tectonics affected biotas. The ocean floor is thus pushed at right angles and in opposite directions away from the crests. According to National Geographic, sea floor spreading and plate tectonics indicate that the continents do move or shift, which supports continental drift theory. Mountain ranges and the location of ancient climatic zones. Ex. An example of a divergent plate boundary is between the North American and European plate. Continental drift also comes along with grave effects such as Volcanoes, Earthquakes, and Tsunamis. The rock formations of eastern North America Western Europe and northwestern Africa were later found to have a common origin and they overlapped in time with the presence of Gondwanaland. What key evidence supports the hypothesis of continental drift? Essay Service Examples Science Continental Drift. For example fossils of Mesosaurus a freshwater reptile have been found both in Brazil and western Africa. Fossils of the seed fern Glossopteris were too heavy to be carried so far by wind. The poster child of scientific theory. One of the strongest pieces of evidence is Continental break up/fit, this is the idea that the continents were once joined together. Fossils and Mountain ranges were his evidences. For example, if you take the mountains ranges of North America and Europe, they align perfectly well. Do now: Draw a convection current and explain why this happens? Glacier grooves are the gaping trenches or landmarks carved out by movement of glacier. Cygnognathus is Fossil from another species of reptile. The rest of the earth was covered with one huge ocean. This drifting takes millions of years to complete this process. EVIDENCE FOR CONTINENTAL DRIFT What evidence supports the theory of continental drift, including polar wandering data sets? Papers provided by EduBirdie writers usually outdo students' samples. Fossil records are strong evidence that the continents do drift. The purpose of this report is to outline the changes and predicted changes in the volcanic regions of Australia. It has been noted that the coastlines of South America and West Africa seem to match up, however more particularly the terrains of separate continents conform as well.
