According to [About.com Geology] the exposition of tectonic is a large musical scale structure. The plates are everlastingly changing positions and geologic evidence shows that they cast trendd the uniform way in the early(prenominal). The accomplishment is very heavy no more than than a centimeter a year. The apparent movement of the plates is dual-lane in three ways: they move unneurotic (converge), the move apart (diverge), or they move prehistoric all(prenominal) former(a) [About.com Geology]. Earthquakes come up along faults, where capacious blocks of rock are grinding late(prenominal) each other. Tectonic motions produce directional pressure, which causes rocks on either aspect of a large fracture to move past each other. The movement is rarely sm ooth; usually the blocks work over because of friction, which slows their movement. Eventually, the friction is overcome and the blocks strip show abruptly, releasing repressed energy with a huge snapan seism (The central office Tectonic Model Page 107). Plates diverge at volcanic zones by the ocean basins. These are long huge cracks were lava rises from below and freezes into the Lithosphere (About.

com Geology). In which plates move past each other is call a transform boundary. These are not that normal as the converge or diverge plates and the intimately super acid one is the San Andreas fault of California [About.com Geology]. The Pacific! edge of the US is the region most susceptible to temblors [essortment.com]. Recently, there has been more action at law specifically in the Caribbean plate (Haiti), the West seacoast of second 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
