Continental Drift
Continental drift is the movement of the Earth 's continents relative to each other. The hypothesis that continents 'drift ' was first put forward by Abraham Ortelius in 1596 and was fully developed by Alfred Wegener in 1912. However, it was not until the development of the theory of plate tectonics in the 1960s, that a sufficientgeological explanation of that movement was found.

[edit]Early history
Abraham Ortelius (Ortelius 1596),[1] Theodor Christoph Lilienthal (1756),[2] Alexander von Humboldt (1801 and 1845),[2] Antonio Snider-Pellegrini (Snider-Pellegrini 1858), and others had noted earlier that the shapes of continents on opposite sides of the Atlantic Ocean (most notably, Africa and South America) seem to fit together.[3] W. J. Kious described Ortelius ' thoughts in this way:[4]

Abraham Ortelius in his work Thesaurus Geographicus ... suggested that the Americas were "torn away from Europe and Africa ... by earthquakes and floods" and went on to say: "The vestiges of the rupture reveal themselves, if someone brings forward a map of the world and considers carefully the coasts of the three [continents]."
[edit]Wegener and his predecessors
The hypothesis that the continents had once formed a single landmass before breaking apart and drifting to their present locations was fully formulated by Alfred Wegener in 1912.[5] Although Wegener 's theory was formed independently and

    Over the years proceeding the birth of the theory, increasingly convincing evidence has been gathered for proof of the theory of plate tectonics. In 1912, Alfred Wegner proposed the theory that continents are sat upon tectonic plates and that these plates are slowly drifting around the Earth (continental drift). Since then, volcanic and seismic events have made up a large proportion of the evidence towards the theory, including volcanic eruptions at both constructive and destructive boundaries, hotspots, sea floor spreading, paleomagnetism, and seismic earthquakes. However, not all of the evidence supporting plate tectonics comes from volcanic and seismic events; other evidence includes continental fit, geological evidence, biological evidence, climatological evidence and other activity at destructive plate margins.…

    The plate tectonics theory was made by a German named Alfred Wegener. He stated that a single continent existed about 300 million years ago named Pangaea and that it split into two continents of Laurasia in the north and Gondwanaland in the south. Today’s continents were formed by further splitting of the two masses.…

    The Plate Tectonic Theory developed in the late 1960’s, when people noticed how continents either side of the Atlantic Ocean seemed to almost fit together. Francis Bacon, an English Philosopher was aware of this as early as 1620. Topographical and geological evidence built up and allowed Alfred Wegener to publish a theory in 1912, suggesting that the continents were once all joined together in a supercontinent he called Pangaea. Wegener proposed that at some time, the land masses had drifted apart until they occupied their current positions on the globe. There was lots of evidence to support his theory including Continental Fit. Sometimes continents, such as the west of Africa and the eastern seaboard of South America, seem to fit together if placed beside each other. This is particularly true is the continental shelves are taken into account as the true edges of the land masses. There is also Geological Evidence where rocks of the same age and type and displaying the same formations, such as in south-east Brazil and South Africa. The trends of the mountains are also similar in eastern USA and North-west Europe. Similar glacial deposits are found in Antarctica, South America and India, which are now many kilometres apart. Climatological Evidence shows that places as far apart as Antarctica, North America and the UK all contain coal deposits of a similar age that were formed in tropical conditions. They are no longer in tropical climate zones and must have drifted apart since the Carboniferous period. Biological Evidence shows that similar fossil formations are found on either side of the Atlantic. Plant remains from humid swamps that later formed coal deposits have been found in India and Antarctica.…

    The discovery of America was one of the most important events recorded in the history of mankind according to Adam Smith because it changed both the Old and New worlds which these changes are still in play today. American and European people did not know of each others existence, but were forced into interaction. Crops from both hemispheres crossed the Atlantic, which reshaped diets and transformed natural environments. North and South America had not developed immunity because of their isolationism and as a result suffered from many epidemics.…

    The plate tectonics theory was put forward by Alfred Wegener suggesting that the continents were at one point all conjoined in one supercontinent known as Pangaea. He then said that Pangaea had drifted apart through the movement of plates to give us the current places of continents we have today. Wegener's theory was linked to a variety of evidence, however it took further research and evidence for this to become a leading theory. This means that although volcanic and seismic events help to prove the plate tectonics theory valid, there is also a range of other factors involved.…

    Alfred Wegner is most associated with continental drift stating that the continental landmasses were drifting apart from each other across the earth and colliding into each other. Wegner came to this conclusion with the evidence that the continents fit together, glacial till deposits, and the shifting of climatic belts over time. Some of Wegner’s colleagues thought polar wandering caused this. It was not until the 1950’s that paleomagnetism, convention currents, and seafloor spreading were added onto these ideas. The world once believed that continental drift was the reason for the positioning of continents and later realized that they were wrong. So what makes the theory of plate tectonics a hundred percent fact? It is just the best hypothesis that we have figured out so far. Not saying it is wrong, but possibly in the future we might be able to produce a better hypothesis with newer technology.…

    The plate-tectonic theory plays a huge part in the beginning years and it tells us that continents as well as ocean floors have rigid plates in the lithosphere and these plates slide over deeper rock in the asthenosphere. The movement of these plates causes breaking and colliding across the globe and this is what in fact formed North America due to all the collisions and then welding together of many smaller continents and some island arcs during the Precambrian time.…

    Alfred Wegener(1880-1930) was the first man to propose the theory gplate tectonics.h He had got a Ph.D in astronomy from the University of Berlin, but he was also interested in the other science field such as geophysics, meteorology, and climatology. He also contributed to meteorology by establishing to track air circulation using balloon. In 1911, he read a paper that listed identical fossils of plants and animals found on opposite side of the Atlantic, and he looked for more of such organisms. At his time, such cases were explained by postulating land bridges which do not exist now. However, Wegener found that coastlines of South America and Africa match closely. As evidences he suggested the similarity of large-scale geological features on separate lands, such as Appalachian Mountains of North America and Scottish Highlands. He also suggested that indicated climate of the place fossils were found often differs from the climate of today. Those evidences lead him to publish Wegenerfs theory of gcontinental drafth in 1915. In the book The Origin of Continents and Oceans, he wrote about 300 million years ago, continents were a single mass, Pangaea, which had split and lifted, and the pieces had been moving since then. However, his theory was lack of explanation of how the continents move. He explained it that it was through the earthfs crust and centrifugal and tidal forces that move the pieces. But as opponents said, it was a mistake. On the other hand, there were supporters of the theory. One of the supporters, geologist Alexander Du Toit, used it to explain the similarity of strata and fossils of Africa and South America. Though Wegnerfs theory did not get enough support during his life time, it is now accepted by almost all geologists, and helped scientists to explore the Earthfs crust, and ocean…
