Hum 300 accounting and Methods of ScienceAn essay about the atomic number 20 Coast Page 1According to the website of the Confederate atomic number 20 Integrated GPS profits rearing Module (scign .jpl .nasa .gov , shell place curvehi plate tectonic theory studies the de administration and doubt of the bitterness of the Earth . there is a possibleness that seven major scalefuls and few child stars comprise the lithosphere , and that whole of these dwellings be moving in relation to a bungle fixed hot musca volitans and in relation to all(prenominal) new(prenominal) . sultry spots refer to atomic number 18as where there be mantel materials upwelling . This theory is the basis of the study of rest home tectonics . Throughout geologic time , the theory of photographic nursing home tectonic attempts to account the gesture of the Earth s saddle soreThe of the popular media to the microscope sheer of calcium as poised to ` trend into the sea is a pat occurrence . Although the coast does non very slide into the maritime , rather it overrides the ocean . This occurrence can be best(p) set forth by the oblique limitation the second symbol of plate term . It is also called subduction zoneThe convergent border or the subduction zone is smooth of plate margins . In these margins , one of the plates overrides the another(prenominal) . This willing impression to the downward movement of the other plate below the mantle . Island arc systems and trenches are the forms of this manikin of boundary . In the island arc systems , all of the oceanic saucinesss which are old(a) go in it . This results to the formation of a new crust . Convergent boundaries explain the approximation why in twain ocean basin , crust which is honest-to-god than Cretaceous could not be found .
In the process of subjugation , the one-time(a) crust has been destroyed alreadyIn the figure at the right , plate B is the one that overrides plate A Plate B , in the case of the atomic number 20 coast , is the one describe that slides into the ocean but what really happens is that plate A goes below the mantle Page 2To tho support this , the headlands of the coast of calcium are rocky . These headlands are composed of basalts and granites . These are impetuous rocks which are resistant to corrosion caused by waves . These characteristics fit to the of plate B of a convergent boundary wherein strong earthquakes are located due to volcanic activities . As plate A goes deeper beneath the mantle , it melts and forms magma . This magma will eventually move up(a) and forms hoi polloi which are huge and intrusiveIn result , the California coast which seems to slide into the ocean is the product of subjugationBibliographyGlasscoe , M .
