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.

This essay sample was donated by a student to help the academic community. (It doesnt.) Continental drift has impacted the universe in many ways. In conclusion we can see that Wegner developed a theory with plenty of evidence that was later even further developed by the discovery of tectonic plates and other factors such as magnetic inclination in rocks and the effects of divergent and convergent plate boundaries. Answer 5: Fossils are formed when living organisms (plants or animals) die and become buried in dirt, sand or mud. These cookies will be stored in your browser only with your consent. DIRECTIONS: Read each evidences given below and answer the questions on 1 whole sheet of paper. Papers provided by EduBirdie writers usually outdo students' samples.

Continental drift describes one of the earliest ways geologists thought continents moved over time. Wegener suggested that when the organisms were alive the lands were joined and the organisms were living side-by-side. Below the lithosphere is the Asthenosphere which is a viscous area with low resistance in the upper mantle often described as plastic rock. answer choices He had no good evidence. It is thought that all the continents were once joined together in one super-continent, named Pangaea. What are the 5 evidences of continental drift? Magnetism in rocks can also be used as evidence for the continental drift. In this essay I will describe more in-depth about the Earths dynamic structure and how plate tectonics affected biotas. What Evidence Supports The Theory Of Continental Drift. The idea of a large-scale displacement of continents has a long history. He suggested that Pangaea broke up long ago and that the continents then moved to their current positions.
