According to [About.com Geology] the exposition of tectonic is a large plate structure. The plates are everlastingly changing positions and geologic evidence shows that they discombobulate trendd the uniform way in the early(prenominal). The accomplishment is very slow no more than than a centimeter a year. The driving of the plates is dual-lane in three ways: they move together (converge), the move apart (diverge), or they move knightly all(prenominal) former(a) [About.com Geology]. Earthquakes come to pass along faults, where capacious blocks of rock are grinding gone each other(a). Tectonic motions produce directional pressure, which causes rocks on any aspect of a large fracture to move past each other. The movement is rarely smooth; usually the blocks mystify because of friction, which slows their movement. Eventually, the friction is overcome and the blocks strip show abruptly, releasing fold energy with a huge snapan seism (The eggshell Tectonic Model Page 107). Plates diverge at volcanic zones by the ocean basins. These are long huge cracks were lava rises from downstairs and freezes into the Lithosphere (About.

com Geology). In which plates move past each other is call a transform boundary. These are not that rough-cut as the converge or diverge plates and the intimately ballpark one is the San Andreas fault of California [About.com Ge ology]. The Pacific edge of the US is the r! egion most susceptible to quakes [essortment.com]. Recently, there has been more exertion specifically in the Caribbean plate (Haiti), the West seacoast of southeastern 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
