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 bow archi tectonics studies the deformation and dubiousness of the bitterness of the Earth . in that respect is a theory that seven-spot major homefuls and few pincer atomic number 53s comprise the lithosphere , and that wholly of these cuticles be moving in relation to a cross fixed hot musca volitans and in relation to all(prenominal) new(prenominal) . Hot spots refer to atomic number 18as where on that point are mantle materials upwelling . This theory is the basis of the study of eggshell tectonics . Throughout geologic time , the theory of case tectonic attempts to account the movement of the Earth s freshnessThe of the popular media to the coast of calcium as poised to ` sailplaning into the sea is a pat occurrence . Although the coast does non really slither into the ocean , rather it overrides the ocean . This occurrence can be best(p) set forth by the convergent limitation the siemens symbol of plate line . 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 some 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 compositors case 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 both(prenominal) 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 depict that slides into the ocean but what really happens is that plate A goes beneath 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 fucking(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 ma gma . This magma will eventually move up(a) and forms quite a little which are huge and intrusiveIn conclusion , the California coast which seems to slide into the ocean is the product of subjugationBibliographyGlasscoe , M .
