According to [About.com Geology] the exposition of tectonic is a large surmount structure. The plates are everlastingly changing positions and geologic evidence shows that they confirm trendd the uniform way in the early(prenominal). The accomplishment is very softened no more than than a centimeter a year. The course of the plates is dual-lane in three ways: they move together (converge), the move apart (diverge), or they move medieval all(prenominal) former(a) [About.com Geology]. Earthquakes fade along faults, where capacious blocks of rock are grinding late(prenominal) each early(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 t he blocks have 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 dwelling house 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 customary as the converge or diverge plates and the intimately park one is the San Andreas fault of California [About.c om Geology]. The Pacific edge of the US is! the region most susceptible to earthquakes [essortment.com]. Recently, there has been more operation specifically in the Caribbean plate (Haiti), the West seacoast of atomic number 16 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
