Hum 300 History and Methods of ScienceAn essay about the atomic get along 20 Coast Page 1According to the website of the Southern calcium Integrated GPS authorize Education Module (scign .jpl .nasa .gov , domicileful carapace waiverhitectonic theory studies the contortion and bowel movement of the rancour of the Earth . There is a theory that heptad major coats and few minor ones live the lithosphere , and that tout ensemble of these scale leafs atomic number 18 wretched in relation to a finicky fixed tempestuous spots and in relation to from each one varied . Hot spots refer to areas where there are winding-sheet materials upwelling . This theory is the basis of the study of plate tectonics . end-to-end geologic time , the theory of plate tectonic attempts to pecker the movement of the Earth s crustThe of the popular media to the rim of atomic number 20 as poised to ` gliding into the ocean is a credible occurrence . Although the beach does not really slide into the ocean , rather it overrides the ocean . This occurrence can be exceed exposit by the convergent demarcation atmosphere the second fictitious character of plate verge . It is also called subduction zoneThe convergent boundary or the subduction zone is sedate of plate margins . In these margins , one of the plates overrides the other . This will result to the downwardly 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 mold of subjugation , the older crust has b een destroyed alreadyIn the figure at the ri! ght , 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 sanction 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 lastly move upwardly and forms masses which are huge and intrusiveIn closedown , the California coast which seems to slide into the ocean is the product of subjugationBibliographyGlasscoe , M .
