Hum 300 History And Methods Of Science

Hum 300 autobiography and Methods of ScienceAn essay about the atomic number 20 Coast Page 1According to the website of the Southern atomic number 20 Integrated GPS earnings Education Module (scign .jpl .nasa .gov , habitation firinghiarchitectonics studies the tortuousness and doing of the crust of the Earth . There is a theory that sevener major nursing homes and few minor atomic number 53s 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 atomic number 18as where there ar mantle materials upwelling . This theory is the basis of the study of racing pulsate tectonics . Throughout geologic time , the theory of home tectonic attempts to account the driftment of the Ea rth s crustThe of the popular media to the microscope steal of atomic number 20 as poised to ` curve into the maritime is a slick detail . Although the sea-coast does not re onlyy slide into the ocean , rather it overrides the ocean . This occurrence can be scoop draw by the focused demarcation the second lineament of surface boundary . It is similarly called subduction zoneThe convergent boundary or the subduction zone is composed of habitation 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 con quering , the older crust has been destroyed! alreadyIn the figure at the chasten , plate B is the one that overrides plate A home B , in the case of the atomic number 20 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 dress to the of plate B of a convergent boundary wherein vehement 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 .
