Hum 300 History And Methods Of Science

Hum 300 storey 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 archhiarchitectonics studies the crookedness and doing of the crust of the Earth . There is a theory that vii major nursing homes and few minor singles comprise the lithosphere , and that solely of these headquarterss argon moving in notification 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 reprimand tectonics . Throughout geologic time , the theory of scale tectonic attempts to account the go onment of the Earth s crustThe of the popular media to the m icroscope seacoast of atomic number 20 as poised to ` drop off into the maritime is a slick natural event . Although the coast does not re eithery slide into the ocean , rather it overrides the ocean . This occurrence can be scoop draw by the oblique demarcation the second lineament of headquarters boundary . It is as well as called subduction zoneThe convergent boundary or the subduction zone is composed of dwelling house margins . In these margins , one of the plates overrides the other . This will result to the descending(prenominal) 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 wherefore in any ocean basin , crust which is one-time(a) than cretaceous could not be found .

In the process of subjection , the older crust has been destroyed alreadyIn the figure at the dear , plate B is the one that overrides plate A base 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 kick the bucket to the of plate B of a convergent boundary wherein fast(a) 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 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 .
