Cintron Sci/205 April 11, 2010 Dr. Dillon, PhD Earthquake Assignment Assessment The Earths satellite shell is a set of racing shells called plate tectonics. According to [About.com Geology] the exposition of tectonic is a large exfoliation structure. The plates are everlastingly changing positions and geologic evidence shows that they hurt trendd the uniform way in the early(prenominal). The accomplishment is very check no more than than a centimeter a year. The fecal matter of the plates is dual-lane in three ways: they move in concert (converge), the move apart (diverge), or they move prehistoric all(prenominal) former(a) [About.com Geology]. Earthquakes excrete along faults, where capacious blocks of rock are grinding early(prenominal) each new(prenominal). Tectonic motions produce directional pressure, which causes rocks on all aspect of a large fracture to move past each other. The movement is rar ely smooth; usually the blocks generate because of friction, which slows their movement. Eventually, the friction is overcome and the blocks strip show abruptly, releasing restrain energy with a huge snapan seism (The coat Tectonic Model Page 107). Plates diverge at volcanic zones by the ocean basins. These are long huge cracks were lava rises from under and freezes into the Lithosphere (About.

com Geology). In which plates move past each other is call a transform boundary. These are not that super acid as the converge or diverge plates and the intimately putting surface one is the San Andreas fault of California [About.com Geology]. The Paci! fic edge of the US is the region most susceptible to quakes [essortment.com]. Recently, there has been more operation specifically in the Caribbean plate (Haiti), the West seacoast of southwesterly America (Chile), the Pacific Islands and other areas in the Asia continent. As I understand it when there is one shift in the plates this creates a global shifting to the other plates in earth. As I mentioned before these plates move all the time scarcely when an earthquake occurs the...If you want to get a full essay, launch it on our website: OrderCustomPaper.com
