Hi, Im Paul

In 1910, a German scientist named Alfred Wegener hypothesized that Earths continents had go. His hypothesis was that exclusively the continents were at once joined together in a mavin realm mass and after bodgeed apart. The melodic theme that continents ladderd belatedly across Earths outdoors became cognize as Continental drift. gibe to Alfred Wegener, the continents drifted together to category the supercontinent, or single landmass, Pangaea. Pangaea existed about three hundred million old develop ago. Over tens of millions of years, Pangaea began breaking apart. From varied scientific fields, Alfred Wegener ga in that respectd place up to support his hypothesis. He in addition studied fossils, land features, and ancient climatical zones. His rise up from land features was that on round continents, chew ranges and coal beds air travel up. For example, mountain ranges on the eastbound facial expression of to the south America and west military position of Africa line up. Wegeners testify from fossils is that fossils of organisms that couldnt be adrift bemuse been found in places now detached by the ocean. For example, lystrosaurus used to live in only in Africa and India. However, redress now, lystrosaurus fossils have been found in Antarctica. A lystrosaurus couldnt have swam all the way from Africa or India to Antarctica.

Alfred Wegeners evidence from ancient climatic zones is that evidence from rocks shows that southeasterly Africa was once rattling cold. Geologists found scratches in rocks and trough left behind glaciers. This shows that Continental glaciers once cover confederation Africa. Wegener then came up with the idea that continental drift moved South Africa away from the South Pole. Today with technology, which Wegener didnt have, we contumacious that there is no such matter as continental drift. A widely held theory that explains the performance of continents is plate tectonics. Subduction and sea-floor facing pages also cause continents to move. Other causes for continents to move are mid-ocean ridges, deep-ocean trenches, and convection currents in the...If you expect to get a wide-eyed essay, order it on our website: Orderessay
