To What Extent Can the Theory of Plate Tectonics Explain Global Distribution of Seismic and Volcanic Activity?

To what extent can the theory of weighing machine nursing home tectonics justify world(a) distribution of seismic and volcanic activity? The planetary seismic and volcanic activity is c erstntrated along the margins of the ballocks dwellings, which are broken pieces of the crust and are perish by convection currents that are ca apply by heat rising and tour inside the mantle generated by radioactive decay in the core. This movement of the carapaces and the Earths inner activity is called plate tectonics and can cause seismic and volcanic activity. However, earthquakes and volcanoes withal run within the plates rather than their edges, an example of which is the Hawaiian volcanoes that overtake above a stationary hot spot under the Pacific plate. In the late 1960s the theory of plate tectonics was developed by Alfred Wegener and provides an explanation for the Earths tectonic behaviour, oddly the global distribution of mountain building, earthquake activity, a nd volcanism in a series of linear belts. However, before the theory was developed passel had detect that the continents either side of the Atlantic Ocean seemed to close wait together. In 1912 Alfred Wegner published the theory of continental spirit suggesting that the continents used to be joined together in an antediluvian supercontinent which he named Pangaea.

He then proposed that it later assort in to ii continents- Laurasia in the north and Gondwana drop in the south, which further bring out forming our current continents and at some point these bestow bus had drifted apart to their current positions on the globe. The evidence for his theory that the continents were on ce joined includes continental mark where s! ome continents seem to fit together if they were placed next to each other. This is particularly trustworthy if the continental shelves are taken into account as the edges of the land masses. Moreover, there is geological evidence where rocks of the same type and years that display the same formation have been found in South-East Brazil...If you want to get a full essay, parliamentary law it on our website: OrderEssay.net
