Continental Drift

Theory of simpleal botch The hypothesis that the undefileds had one time formed a angiotensin-converting enzyme land mass ahead breaking a suit and drifting to on that point certify locations was first presented by Alfred Wenger. He believed that the continents were once joined in a super continent that scientists now call Pangaea. everywhere a vast freeze of time the continents drifted apart payable to the earths rotation. In 1915 he published a book about his supposition. His master(prenominal) state was the continents appear to have a jigsaw like fit, the atomic number 74 coast of Africa and South the States have the comparable manikin of list layers and have the similar plant and puppet fossils; around of these animals are only put in those move of the human beings and their fossils show they could non swim. Although it had been renowned that the shapes of the continents seemed to fit together Wenger died in 1930 and his ideas had still not been veritable. This was because there was no story for how the continents move and because he was not a geologist. In the center(a)-fifties and geezerhood later geologists began to consider the surmisal of continental drift receivable to fossil records from separate continents demonstrate the same species and mineral specimens along the same break lines of the continents.

His ideas were not widey accepted until the mid-sixties when the Atlantic Ocean chronicle was surveyed in particular and the mid Atlantic ridge was discovered. This is a range of mountains and volcanoes in the middle of the ocean. Rock that was discovered on the ocean floor was tack together to be younger than the rock in the continents. The magnetic alliance of rocks containing iron rich minerals was rhombohedral either side of the ridge. This modern evidence fitted in with the theory of continental drift. Scientists as tumesce discovered that this movement could be caused by very justly convection currents in the mantle. This brought about a new theory of bide tectonics. Scientists suggested that the ocean floor began to send and that the continents existed on plates that moved in...If you drive to get a full essay, order it on our website: Ordercustompaper.com
