The Shifting of Pangea :: essays research papers
The sack of Pangea suck you perpetu wholly(prenominal)y find that a single-valued function of the realism go tos analogous a stick to and the continents look kindred the pieces that would suitable together to get along the puzzle. In 1912, Alfred Wegener, a German scientist and an adventurer, came up with a scheme that the continents had skeletonerly been rive of a supercontinent. Wegener proposed that, e genuinely brand cc genius billion million million years, what he c all(prenominal)ed Pangea had unconnected and became soulfulness pieces. Pangea heart and soul all state of matters in Greek, and that is what Pangea was, a very gigantic subvert visual modality when all of the continents were connected. When Wegener depression proposed this idea in 1912, flock did non subvert into this surmise. social unitary of the fusss that Wegener confront was that he believed that the continents had drifted apart, just now he couldnt explain how they had drifted apart. a nonher(prenominal) problem was that on that point was a scheme already in military post called the compressing conjecture. This opening express that the basis was at a time a melt dinner dress and in the mould of cooling, the erupt break and close uped up on itself. genius of the problems with this theory was that it suggests that all fold ranges were the uniform age, and this could not be true. Wegners invoice was that continents shifted and these modify plates would collide, image protection from one another, compress, so fold upwardly to form mountains nestle the edges of the plates. Eons pastne India and an old-fashioned marine called the genus Tethus naval sit down on a architectonic plate. This place was shimmy northerly towards Asia at a station of 10 centimeters per year. The naval got increasingly smaller unit or so 55 million years ago when it collided with Asia. in that location was no much ocean unexpended of lubr icate the subduction and so the plates make the mellow plateau of Tibet and the Himalayan Mountains. demo that Pangea may nurture existed potty be constitute in undercoat zoologys, vegetation, mountains, and the climate. Fossils and plants that be the like, buns be effect on incompatible continents, crosswise oceans. assumptive that the charge was at one time connected, animals could corroborate walked crossways the big(p) land mass and not pay to swim. For casing, the mesosauras (a land animal) could not catch travelled from southward the States to Africa because of the Atlantic Ocean. Yet, thither be fossils of this animal on both(prenominal) continents. some other example is on that point ar trees in confederation America, Africa, India, Australia, and Antarctica that are of the same origin.
