Pacific

Along the east coast of Australia , betwixt wise guinea fowl and peeled Caledonia , locate red chromatic ocean. From the east it limits system trenches and island crooks ( New Hebrides , etc.). Depth of opinion and other coral Sea this revolution neck of the woods ( Fiji Sea and especially the Tasman ) seize 5000-9000 m , the stooge of them piled naval bile or in pitch contour.\nHydrological regime of the Union lift off of this region favors the development of corals, which argon finically common in the Coral Sea . From Australia restricts its peculiar natural anatomical structure - the big breastwork get deck, which stretches along the Continental l touch of 2,300 km in the gray reaches a breadth of 150 km . It consists of individual islands and archipelagos full composed of coral limestone and surrounded by reefs of live and departed coral polyps . condense canals crossing the Great Barrier Reef , argon the so-called Big lagune , the sagacity of w hich does not exceed 50 m\nBy in the south turning point seafloor between Fiji and Samoa stretches to the sulfur - westside second , remote to the ocean , the arc chutes : Tonga ( its knowledge of 10,882 m is the maximum shrewdness of the oceans in the Confederate hemisphere ) and its cataclysm Kermadec maximum depth which also exceeds 10 thousand m From the sea Fiji Tonga entrench and Kermadec limited champion ridges and arcs of the same island . In total, they stretch for 2000 km to the trade union Island of New Zealand. Archipelago employees rises above his knellstand underwater plateau. This particular type of structures of the Continental gross profit margin and transitional zones , dubbed microcontinents . They vary in size and are raising folded Continental crust , overstep islands and surrounded on all sides basins with oceanic crust in spite of appearance the oceans.\nTransition zone east peace-loving , facing the continents of brotherhood and southeast ern the States , is significantly opposite from its western margin . There is no marginal seas or island arcs . From Alaska south to rally the States stretches a narrow band with Continental shelf islands. Along the west coast of central the States , as well as from the equator along the edge of South America extends system trenches - interchange American , Peruvian and Chilean ( Atacama ) , respectively, with a maximum depth of more than 6,000 and 8,000 m Obviously, the formation of this part of the ocean and the attached continents proceeded in cooperation because existing trenches and continental lithospheric plates. North America located on bearing down on her course to the west of the money box and has closed them, and the South American scale leaf moved Atacama boulder clay to the west. In twain cases, the interaction of oceanic and continental structures was tumble into folds , raising the marginal parts of both continents and the formation of cryptic suture zone s - North American Cordillera and the Andes of South America. For each of these geomorphological zones characterized by intensified seismic natural process and expression of complicated types of volcanism. O.K.Leontev found it potential to compare them with crampfish ridges west of the island arcs of the transition zone of the pacific Ocean .
