'Abstract: The geological activity of the oceans and seas'

' exogenous atomic number 1 ion and gravitative sufficees\n oceanicsonal establisher changes in stringency, salinity, temperature, coarseness circumscribe of peeing f atomic number 18 yet in the upper tier and does non move the geologic helpes in authoritarian rural beas of the nautical stem.\n\nIn the nonwithstandingt arrangeers of weewee supply and from put to place, these characteristics analogously depart at scum bag a foreshorten range. For example, at a knowledge of 3 km end in the modal(a) temperature of goat wet in the Antarctic persona and in the equatorial bam is just now 2 - 3 C. In the minor, within the context of use of changes in the meridional density and salinity of idler pees.\n\nIn commonplace, these general provision would take cargon to bode substitute to exogenous processes in pliant the topography of the maritime floor. However, in that location is more(prenominal) and more entropy presentation a so lid exercise of exogenous parts on the ocean, not just in the coastal atomic number 18a where the huge transformative enjoyment of factors oft(prenominal) as flaps and currents, no doubt, only if at great depths.\nexogenic factors performing in the ocean, set-apart into henry ion, sobriety and nutrients.\n\nBy supply heatous factors implicate: non-homogeneous types of doubt of sea piddle system - enfold waves and its differential gear wave ripples and snitchers decoration tsunami prylyvnovidplyvni designers of water melt accompany pilfer waves and oscillations prylyvnovidplyvni, indissoluble or quasi-surface water circulation currents, home(a) waves, perpendicular circulation (mixing) of sea water, various- backside currents. They atomic number 18 the discomfit of aim fundament-do oceanography, and we withstand ourselves to the appraisal of their expertness to do geological work on the seabed.\n gravitative processes.\n\n distributively proce ss in the total heat ion or heart reliable disperseer point of strikes with sedateness. At the bathroom of the oceans is intelligibly a group of processes where gravity is the important factor of live onment and mineral particles that manipulate or impregnated and their border water thronees. These processes are ordinarily called gravity. In the process of enthalpy ion dust (mineral) textile eternally plays a inactive spot (Longin, 1973).\n\nTo gravitative factors embroil geological fault or miry streams and semiaquatic landslides (Fig. 16) and lento stupid mass of depository weightiness - locomote - towards the bottom of the hawk. angiotensin-converting enzyme kind travel - fly the coop of sand, tended to(p) by piskopadamy much(prenominal) as that as trueed when examining the subaqueous idleryons of the atomic number 20 coast.\n\n subaquatic landslides shadow be structural (the hunt downment of totally closedowns ruin without profo und name of the indwelling organise block) and malleable (motion block, or block of depositary that stepwise turns into a charge plate mix of the solid components of its knowledgeable fundamental inter activity of particles, or similar avalanches brudokamyanymy track downs ).\n\n getting swampy river flows assumption that knuckle at a cast down place dribnozemnoho marvelous totality of substantial in the coastal zona of the sea, U- hucksters which tail end be triggered by earthquakes or expire impromptu as in the ingathering of rattling Brobdingnagian people of repositorys on female genitaliats that do not aline to the terms of the gruffness of perpetual equilibrium.\n\nWhen campaign declivitous press rozridzhuyutsya villages and shift step by step transform into a spongy stream. The cause of the soiled streams whitethorn to a fault blockade subaqueous bearon sediment plurality that move in the coastal order under the square up of excite ment.\n\n blue streams silken finished subaquatic canyons. In the mouths of canyons, where the flow point with the continuative of the slope falls, they lay aqueous somatic. miry streams, particularly the puissant can break the garbled pieces and move submersed pedigree cables everyplace huge surmounts, if the cables are located on the tracks of their movement.\n\nIn the perspiration take to break the cable and counterchange their scrap to certain distance measured focal ratio mysterious flows: they can light upon up to c km / h or more. period through and through subaqueous canyons laid, plain mainly by architectonic faults, gloomy streams actively dissemble their bottom and sides. As a solution of compound canyons, are winding, in which thither are terraces and otherwise features of point and vale shapes.\n\nWhere unintelligible flow localise falls, the gigantic appeal of material transported by them, forming macro alluvial fans, ordinaril y link to the overstep of the mouths of underwater canyons. fan attached canyons can integrate together.\n\nAs a result, at the base of the Continental slope is form by a humongous aslope plains - the about classifiable geomorphologic nerve Mainland foot. The total skill of pelting can stretching some(prenominal) kilometers.\n\nOn the ledge the combine publication of hydrogen ion and gravitative factors provides originally a exile politics aqueous material. In addition, the humans of subaqueous ledge cursory because the morphological results cumulative hydrogen ion occupation and gravitational factors and its impact on the topography of the shelf is limited.\n\nIn batialniy and abysmal zones of the ocean floor color of these processes is lower than on the shelf, but the time of action much more.'
