Hum 300 History And Methods Of Science

Hum 300 news report and Methods of ScienceAn essay about the calcium Coast Page 1According to the website of the Southern atomic number 20 Integrated GPS earnings Education Module (scign .jpl .nasa .gov , habitation electric archiarchitectonics studies the overrefinement and doing of the crust of the Earth . There is a theory that septenary major nursing homes and few minor one(a)s comprise the lithosphere , and that solely of these headquarterss argon moving in sexual intercourse to a circumstance fixed hot spots and in relation to distributively other(a) . Hot spots refer to aras where there ar mantle materials upwelling . This theory is the basis of the study of racing perplex tectonics . Throughout geologic time , the theory of base tectonic attempts to account the take upment of the Earth s crustThe of t he popular media to the microscope soaring of atomic number 20 as poised to ` sneak into the maritime is a slick incident . Although the soaring does non re solelyy slide into the ocean , rather it overrides the ocean . This occurrence can be scoop draw by the convergent demarcation the second lineament of scale leaf boundary . It is excessively called subduction zoneThe convergent boundary or the subduction zone is composed of abode margins . In these margins , one of the plates overrides the other . This will result to the down movement of the other plate below the mantle . Island arc systems and trenches are the forms of this type of boundary . In the island arc systems , all of the oceanic crusts which are quondam(a) go in it . This results to the formation of a new crust . Convergent boundaries explain the idea why in any ocean basin , crust which is one-time(a) than cretaceous could not be found .

In the process of oppressiveness , the older crust has been destroyed alreadyIn the figure at the recompense , plate B is the one that overrides plate A household B , in the case of the calcium coast , is the one described 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 fervid rocks which are resistant to erosion caused by waves . These characteristics burst to the of plate B of a convergent boundary wherein concentrated earthquakes are located due to volcanic activities . As plate A goes deeper beneath the mantle , it melt s and forms magma . This magma will eventually move upwardly and forms masses which are huge and intrusiveIn conclusion , the California coast which seems to slide into the ocean is the product of subjugationBibliographyGlasscoe , M .
