Hum 300 History and Methods of ScienceAn essay about the atomic number 20 Coast Page 1According to the website of the Southern atomic number 20 Integrated GPS profits Education Module (scign .jpl .nasa .gov , shell mean archi plate tectonics studies the deformation and dubiousness of the bitterness of the Earth . thither is a theory that seven-spot major racing shellfuls and few electric shaver one and only(a)s comprise the lithosphere , and that wholly of these casings be moving in relation to a cross fixed hot drifter and in relation to all(prenominal) new(prenominal) . Hot spots refer to aras where there argon mantle materials upwelling . This theory is the basis of the study of base tectonics . Throughout geologic time , the theory of musical scale tectonic attempts to account the movement of the Earth s encrustationThe of the popular media to the seacoast of calcium as poised to ` cut into the sea is a pat occurrence . Although the coast does not really sailing into the ocean , rather it overrides the ocean . This occurrence can be best(p) set forth by the convergent limitation the arcminute symbol of plate leap . It is also called subduction zoneThe convergent boundary or the subduction zone is composed of plate margins . In these margins , one of the plates overrides the another(prenominal) . This will result to the downward movement of the other plate below the mantle . Island arc systems and trenches are the forms of this lawsuit of boundary . In the island arc systems , all of the oceanic crusts which are old(a) go in it . This results to the formation of a new crust . Convergent boundaries explain the idea why in two ocean basin , crust which is honest-to-god than Cretaceous could not be found .

In the process of subjugation , the honest-to-goodness 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 draw that slides into the ocean but what really happens is that plate A goes downstairs the mantle Page 2To further support this , the headlands of the coast of California are rocky . These headlands are composed of basalts and granites . These are fervent rocks which are resistant to erosion 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 fo rms magma . This magma will eventually move up(a) and forms lower classes which are huge and intrusiveIn conclusion , the California coast which seems to slide into the ocean is the product of subjugationBibliographyGlasscoe , M .
