Why do you believe that General Mejia refers to Mexico as a friendly nation? 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. Well, this claim was made in the 90s by Alfred Wegener, a German polar researcher, meteorologist and geophysicist who died in 1930.

The shores of Red Sea exhibits evidence of having undergone lateral displacement /Sea flow spreading It has affected the global climate, the worlds geographical positions and the evolution of animals. By Staff Writer Last Updated March 29, 2020 According to National Geographic, sea floor spreading and plate tectonics indicate that the continents do move or shift, which supports continental drift theory. Wegener supported his theory by demonstrating the biological and geological similarities between continents. When he was tasked with proving how these continents moved to different places, he couldnt. DIRECTIONS: Read each evidences given below and answer the questions on 1 whole sheet of paper. Well, we do. Sea floor spreading indicates that since the continents presently move apart, previous continental drift was possible and probable as well. Which example is another piece of evidence? 3 Which is evidence supporting the theory of continental drift? Alfred Wegener, in the first three decades of this century, and DuToit in the 1920s and 1930s gathered evidence that the continents had moved.

The mantle is a layer of red hot, semi-molten magma in which heat rises and falls. Destruction happens when one plate moves below the other at convergent boundaries. 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. B. Some Southern Hemisphere geologists, particularly in South Africa, responded with enthusiasm. It will explore the theory of continental drift by Alfred Wagener and the more advanced and developed theory of plate tectonics and how it has affected the volcanic hotspots and also provides several predictions for the future of Australias volcanos.

Post navigation PreviousPrevious post:Is Styrofoam bad for the environment? When this occurs, the sea floor grows wider, pushing the two continents apart. Studies by Runcorn of the remanent magnetism in suitable rocks of different ages from Europe produced a polar wandering curve indicating that the magnetic poles were in different places at different times. Wegener suggested that when the organisms were alive the lands were joined and the organisms were living side-by-side. Oceanic ridges occur along some of the plate margins. Correct answers: 1 question: In your own words, explain the scientific evidence that supports the continental drift theory. This concept was an important precursor to the development of the theory of plate tectonics, which incorporates it. Whilst the theory that the continents had moved over time had been speculated upon before, the theory wasnt properly developed until 1912. He suggested that all the continents had once formed a single land mass or super continent which he called Pangaea; the ancient Greek meaning for 'All Earth'. He suggested that Pangaea broke up long ago and that the continents then moved to their current positions.

Mesosaurus If you look at the map before the continents drifted away, you find that Cygnognathus was situated in South America and Africa. According to Wegener's hypothesis of continental drift, Pangaea, a Mega Ocean surrounding a supercontinent that . Rodinia lasted around 500 million years before it began to break apart and rejoin together to form Pangaea which is seen as the origin of the continents we have today. Which of the following could be considered a geographic factor in westward migration? . Glossopteris - plant remains found in South America, Australia, Asia and Africa. What are the 5 evidences of continental drift? The discovery of plate tectonics in the 1960s provided a possible mechanism for continental drift, and since then the study of continental drift . Where this is the case, the lithospheric plates separate, and the upwelling mantle material forms new ocean floor along the trailing edges. The Emu and Cassowary (Australia), Kiwi and Moa (New Zealand ), Rhea (South America) and Ostrich ( Africa) are members of a kin bird group called Ratites. The Theory of Continental Drift was proposed by Alfred Wegener in 1912. Cygnognathus is Fossil from another species of reptile. Updates?

As molten rock rises from the Earth, it forms new crust between the plates. Was the United States justified in going to war with Mexico? More evidence was needed, and it came from the Earth's magnetism. 2 What are some of the major pieces of evidence for the theory of plate tectonics? This apparent fit is due to the fact the continents were once connected and have since moved apart in what has been called continental drift . identical rocks, mountains and structures. Privacy Policy The puzzle-like fit of the continents especially Africa and South America. Which of the following explains how the map shows evidence for the existence of Pangea?

Striations are scratches or grooves created by glacial debris as it moves. On aligning the continental coast margins, Wegener observed that the striations all pointed towards the pole. Aside from the congruency of continental shelf margins across the Atlantic, modern proponents of continental drift have amassed impressive geologic evidence to support their views. The continents continued to shift through the Jurassic and Cretaceous periods until the present day. For millions of years, all the land of Earth was joined together in a supercontinent, which is known as Pangaea. Geological features are best explained by continents' movement over a layer of mantle, the lithosphere. Geological fit evidence is the matching of large-scale geological features on different continents. Bringing together a large mass of geologic and paleontological data, Wegener postulated that throughout most of geologic time there was only one continent, which he called Pangea. However, this theory of continental drift came to be accepted in the 90s after his death.

Web continental drift theory what evidence did wegener use to support his hypothesis? Privacy Policy . 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). The supercontinent was surrounded by water bodies, mainly oceans, and seas. This means it does not absorb, emit or reflect visible light, gamma rays, ultra-violet rays etc. Ferromagnetic minerals such as magnetite acquire a permanent magnetization when they crystallize as constituents of igneous rock. . The poster child of scientific theory. The northern continent consists of Europe, North America, and Asia. Continental drift describes one of the earliest ways geologists thought continents moved over time.
