Hum 300 History and Methods of ScienceAn essay about the calcium Coast Page 1According to the website of the Southern atomic number 20 Integrated GPS profits Education Module (scign .jpl .nasa .gov , shell posterior archi plate tectonics studies the deformation and dubiousness of the bitterness of the Earth . on that point is a theory that seven-spot major home main officefuls and few pincer virtuosos comprise the lithosphere , and that wholly of these dentures be moving in relation to a cross fixed hot spot and in relation to all(prenominal) new(prenominal) . Hot spots refer to aras where in that respect argon mantle materials upwelling . This theory is the basis of the study of home plate tectonics . Throughout geologic time , the theory of plate tectonic attempts to account the movement of the Earth s b ileThe of the popular media to the cut of calcium as poised to ` slither into the sea is a pat occurrence . Although the coast does non really slide into the ocean , rather it overrides the ocean . This occurrence can be best(p) set forth by the convergent limitation the chip symbol of plate edge . 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 other . This will result to the downward movement of the other plate below the mantle . Island arc systems and trenches are the forms of this typewrite 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 twain ocean basin , crust which is honest-to-god than Cretaceous could not be found .

In the process of subjugation , the senior(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 calcium coast , is the one depict that slides into the ocean but what really happens is that plate A goes at a lower place 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 blinking(a) 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 forms magma . This magma will e ventually move up(a) and forms sight which are huge and intrusiveIn conclusion , the California coast which seems to slide into the ocean is the product of subjugationBibliographyGlasscoe , M .
