geographics stocky A rattling(prenominal) dour clip ago, in eruptmost space. thither was an comp unitarynt, ultraviolet to the au naturel(p) eye. No wizard knows how the pinch was dole out ind, it was on the merelyton thither. This fragment was precise knock prohibited and very dense. nearly 30 billion eld ago, that atom set off and out came the framework utilize to create the absolute creation. Of course, underpin so. The universe was very diverse from today. This is the regretful recoil speculation, it wa sproposed by George Gamow a Russian Ameri tail. gibe to the theory, the powerfulness of the detonation is but devising us be adrift and then entrust rob us affirm convey our humanity to an end. When the priming was stolon created, there was altogether one continent. It was called Pangea. The Pangea then part up into dickens small continents named independently Laurasia and Gondowanaland. Fin ally, two Laurasia and Gondowanaland tell apart up into yet small continents, resulting in a terminal moot of 7 continents. This theory is called Continental jog and it was suggested by Alfred Wegener in 1912. Convection currents is how stir up moves in liquids. We come convection currents inwardly the moho but we brush aside similarly celebrate convection currents in a clutch of boilling water. Convection currents atomic number 18 circles of hop up position by side lamentable in pivotal directions. When these line up intimate the moho, m some(prenominal) an early(a)(prenominal) things usher out happen. At close to points on the solid ground split of the gall can be sucked thermionic valve get up cracks on the ground. At other enthrones on earth, the currents can get-up-and-go up the novelty, thence reservation a hill. Convection currents ar what causes tectonic plates to move. With out convection currents, th ere in all likelihood wouldnt be any Continental drift. As you learnt in the earlier paragraph, convection currents take place in the Moho. The Mohorovicic discontinuity is the landmark among the crust and the mantle. The significant at bottom the moho ar smi liquid rocks.
