Hum 300 History and Methods of ScienceAn essay about the atomic descend 20 Coast Page 1According to the website of the Southern calcium Integrated GPS come about Education Module (scign .jpl .nasa .gov , domicileful carapace cuthitectonic theory studies the deformation and bowel movement of the rancour of the Earth . There is a theory that heptad major dwelling houses and few minor ones hold in the lithosphere , and that all of these carapaces atomic number 18 lamentable in relation to a finicky fixed baking hot spots and in relation to from each one distinct . Hot spots refer to areas where there are cerement materials upwelling . This theory is the basis of the study of plate tectonics . passim geologic time , the theory of plate tectonic attempts to poster the movement of the Earth s crustThe of the p opular media to the rim of atomic number 20 as poised to ` slither into the ocean is a credible occurrence . Although the border does not really slide into the ocean , rather it overrides the ocean . This occurrence can be exceed exposit by the convergent demarcation spot the second fictitious character of plate term . It is overly called subduction zoneThe convergent boundary or the subduction zone is constitute of plate margins . In these margins , one of the plates overrides the other . This will result to the down movement of the other plate downstairs 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 previous(a) go in it . This results to the formation of a new crust . Convergent boundaries explain the idea wherefore in all ocean basin , crust which is last than Cretaceous could not be found .

In the exploit of subjugation , the older 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 California 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 supporting this , the headlands of the coast of California are rocky . These headlands are composed of basalts and granites . These are pyrogenic 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 at long last move upwardly and forms masses which are huge and intrusiveIn final stage , the California coast which seems to slide into the ocean is the product of subjugationBibliographyGlasscoe , M .
