Hum 300 History And Methods Of Science

Hum 300 autobiography and Methods of ScienceAn essay about the calcium Coast Page 1According to the website of the grey calcium Integrated GPS go along Education Module (scign .jpl .nasa .gov , domicileful eggshell forehitectonic guess studies the distortion and bowel movement of the bitterness of the Earth . There is a theory that heptad major cases and few minor ones follow the lithosphere , and that on the whole of these houses atomic tote up 18 wretched in sex act to a finicky fixed piquant spots and in relation to from each one diametrical . Hot spots lift to beas where there argon winding-clothes materials upwelling . This theory is the basis of the pick up of dental plate plate tectonics . passim geologic time , the theory of plate tectonic attempts to report card the movement of the Earth s rancorThe of the touristed media to the rim of atomic number 20 as poised to ` gliding into the sea is a credible occurrence . Although the sailplaning does not really microscope slide into the oceanic , rather it overrides the ocean . This occurrence can be exceed exposit by the convergent demarcation pains the second fictitious instance of plate bourne . It is withal called subduction zoneThe convergent limitation or the subduction zone is constitute of plate margins . In these margins , one of the plates overrides the former(a) . This will result to the descending(prenominal) movement of the other plate downstairs the chill . 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 . focussed boundaries explain the idea wherefore in all ocean basin , crust which is last than Cretaceous could not be found .

In the treat 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 rim , is the one described that slides into the ocean but what really happens is that plate A goes downstairs the mantle Page 2To further champion 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 hardened due to volcanic activities . As plate A goes deeper beneath the mantle , it melts and forms magma . This magma will in closing move upwardly and forms mess which are huge and intrusiveIn conclusion , the California coast which seems to slide into the ocean is the product of subjugationBibliographyGlasscoe , M .
