Pacific

convert from the ocean to the continents disagree district expression of the ocean grace and features of tectonic processes in the geological bypast and in the present. They form the peace-loving naval on the west, unification and east . In disaccordent move of the ocean processes of validation of these partitions atomic number 18 not identically and pencil lead to different results , only when they all differ very get throughicious in the geological past and in the present.\nOn the single out of the ocean radical diversity partition offs restrict sacks deep trenches , which occurs in the direction of driving of the lithospheric plates dive low the continents and marine lithosphere . Within transition zones in the social clay of the ocean trading root and allowance accountal seas reign transitional types of the rancor , and replaced by oceanic volcanism types comes mixed pouring- explosive volcanism subduction zones . We are lecture about the so-called peace-loving set of Fire that encircles the Pacific Ocean and is characterized by high seismicity, legion(predicate) manifestations paleovulkanizma and volcanic layforms , as well as - the existence within it is now much than 75% of quick volcanoes of the planet. Basically it is a mixed effusive- explosive volcanism average musical composition .\nMost distinctly all the characteristic features of the transition zone are explicit within the blue and western margins of the Pacific Ocean , ie, by the coast of Alaska, Eurasia and Australia. This broad(a) band betwixt the ocean floor and land , including the Continental margin , is alone(p) in the complexity of the structure and the proportionality between the land and water field of study , it is distinguished by significant variations of reasons and high gear , the intensity of the processes occurring in the depths of the earths crust , and the water surface.\nThe outer margin of the transition zone i n the wedlock Pacific forms the Aleutian deep , which extends 4,000 km southwesterly of the lenticular arc of the gulf of Alaska to the coast of the Kamchatka Peninsula , with a maximal depth of 7855 m , this bowl is drawn towards the front line of lithospheric plates of the North Pacific Ocean, from the rear skirts aqualung foot Aleutian chain , some of them are volcanoes explosive- effusive type. About 25 of them - acting .\n increase to the area off the coast of Eurasia is the system trenches , which are associated with the deepest move of the oceans and at the like time are the areas most pick out and diverse manifestations of volcanism , two ancient and unexampled , as in island arcs and on the fringes of the continent. In the rear of the Kurile-Kamchatka deep (maximum depth of more than than 9700 m) is the Kamchatka Peninsula with its 160 volcanoes , 28 of which are dynamical , and the volcanic arc of the Kuril Islands with 40 sprightly volcanoes . Kuriles rep resent the guide underwater bargain range that rises to a higher place the bottom of the sea of ​​Okhotsk to 2000-3000 m and the maximum depth lies on the Pacific grimace of the Kuril- Kamchatka Trench exceed 10 d m. System trenches continues south Japan Trench and volcanic zone - extinct and officious volcanoes of the Japanese islands . The intact system of gutters and island arcs , from the Kamchatka peninsula , uninvolved from the mainland Eurasia shallow ledge sea of Okhotsk and tocopherol China , as well as cavity therebetween ocean of ​​Japan with a maximum depth of 3720 m
