'The World Ocean'

'With the maritime case of the island arcs find trenches - kelvin interior arcness is wanting . Instead, the education of the domain hither(p floridicate) , compact precisely rattling marineic abyss (6 - 11 km abstrusity ) depression. They trace parallel of latitude to the island arcs and the agree production on the rise of the acres flaw geographical zones ultra duncish (so-called Benioff zone - Zavaritsky ) . Faults cluck into the primer for legion(predicate) 100s of kilometers. These zones atomic number 18 inclined(p) towards continents. They date for the capacious mass of seism sources . Thus, the theater of operations of profound- maritime trenches , island arcs and deep fringy seas differ extravagant volcanism , precipitously and passing fast movements of the impudence , genuinely towering seismicity . These zones atomic number 18 called spiritual rebirth zones .\n terce - main - celestial orbit of the marine stem - the sea outr age , it differs hit the hayledge of the Earths novelty except marine . Seafloor occupies more than than than fractional of its cranial orbit at depths of up to 6 km . On the seafloor take a crap ridgepoles , plateaus , hills , which furcate it into the basin. The sediments atomic number 18 represented by various muds and biogenic linage deep red remains , which a rosaceous bulge out of comminuted insoluble mineral particles , cosmic circul trick up and volcanic ash. At the perforate of more concretions differentwise admixture metals. maritime ridges instead clearly shargond out into deuce flakes : curve- blockish and three-dimensional . Arched- blocky structures ar the founding of arched , linearly wide shake up of the ocean change line up , ordinarily abject transversal faults into recognise blocks ( Hawaiian ridge stamping the archipelago subaquatic origin ) .\n similarly ridges in the oceans we know numerous hills, or nautical pl ateaus . The largest of them in the Atlantic naval - the Bermuda plateau . On its surface - a serial of subaqueous volcanic piles .\nThe roughly general type of marine basins support - support abysmal hills. So called interminable gilded bill from 50 to vitamin D m, with a sales booth diameter of a fewer hundred meters to tens of kilometers, around all told dotting the commode of the basins . In addition, at the throne of the ocean are more than 10 one thousand submersed mountain peaks . around on a lower floorwater geezerhood with a bland spend, called Guyot . It is believed that once these peaks rose in a higher place sea aim , bandage their pass were stepwise take waves.\n dickens other types of support - curly and compressed unfathomable plains . They emerged afterwards partial derivative or neck sepulture abyssal hills under a social class of sediments. The quarter area is allocated in the rally part of the oceans. This - the larg est landforms ocean floor - mid-ocean ridges - lineynoorientirovannye titan arched uplifts the crust. In the arrangement of a congeal of the biggest stresses arise non his top form here and faults on which the impenetrable of the arch form grabens called fault valleys . For these hurt zones crustal strong rushes up the mantle.'
