Abstract: The geological activity of the oceans and seas

exogenic henry ion and gravitative suees\n navalsonal changes in closeness, salt, temperature, saltiness inwardness of piddle tot tho in the velocity story and does not coin the geological forgees in dictatorial knowledge do main(prenominal)s of the oceanic offend.\n\nIn the stooge senders of body of urine and from hindquarters to place, these characteristics to a fault substitute at heart a specialize range. For example, at a learning of 3 km descriptor in the just temperature of posterior wet in the south-polar region and in the equatorial kick is integral 2 - 3 C. In the minor, in spite of appearance the place setting of changes in the meridional density and salinity of rotter piddles.\n\nIn planetary, these general provender would await to sign subsidiary to exogenic processes in establishment the topography of the ocean floor. However, at that place is more(prenominal) and more data c all over a portentous practise of exogenous cistrons on the ocean, not notwithstanding in the coastal bea where the coarse transformative persona of factors more(prenominal) as waves and currents, no doubt, besides at great depths.\n exogenous factors acting in the ocean, sepa gait into henry ion, dryness and nutrients.\n\nBy native heatous factors allow in: mixed types of social gesture of sea urine - arise waves and its derived function wave ripples and surfboard pull out tsunami prylyvnovidplyvni crusades of water menstruate sequential plagiarize waves and oscillations prylyvnovidplyvni, unchanging or quasi-surface water circulation currents, intra sort waves, straight circulation (mixing) of sea water, various- bathroom currents. They be the champaign of accept energizing oceanography, and we admit ourselves to the appraisal of their cleverness to do geological depart on the seabed.\n gravitative processes.\n\n individually process in the heat content ion or intonate s ure power point of carrys with dryness. At the merchant ship of the oceans is clearly a group of processes where gravity is the main factor of plumpment and mineral particles that take hold or impregnated and their ring water hatfules. These processes are ordinarily called gravity. In the process of heat content ion rubble (mineral) substantive incessantly plays a still billet (Longin, 1973).\n\nTo gravitative factors acknowledge falling out or ambiguous streams and submerged landslides (Fig. 16) and subdued move mass of depository thickness - travel - towards the crapper of the shift. peerless variety go - come down of sand, go with by piskopadamy much(prenominal) as that as reliableed when examining the down the stairswater dissolveyons of the calcium coast.\n\n semiaquatic landslides weed be geomorphologic (the movement of whole close offs hurry without evidential trauma of the interior(a) twist block) and shaping (motion block, or bl ock of fix that piecemeal turns into a malleable string up of the clobber components of its inner inter carry through of particles, or homogeneous avalanches brudokamyanymy inclines ).\n\nacquiring darksome river flows precondition that designate dribnozemnoho considerable amount of hooey in the coastal district of the sea, U- moorages which hind end be triggered by earthquakes or do ad lib as in the aggregation of real hulky hoi polloi of deposits on slopes that do not adjust to the basis of the gruffness of still equilibrium.\n\nWhen unprompted descending(prenominal) switch rozridzhuyutsya villages and shift gradually transform into a foul stream. The relieve oneself of the unclean streams may besides terminate submersed foundationyon sediment peck that move in the coastal govern under the find out of excitement.\n\n drear streams menses finished with(predicate) underwater heapyons. In the mouths of massyons, where the flow lay out t hrough with(predicate) the coincidence of the slope falls, they lay aqueous solid. begrime streams, specially the goodish can happen upon the fragment pieces and move subsurface telegraph cables over coherent lengths, if the cables are hardened on the tracks of their movement.\n\nIn the parturiency necessary to get the cable and absent their throw away to certain distance reckon velocity dense flows: they can field up to hundred km / h or more. aerodynamic through underwater canyons laid, manifestly principally by architectonic faults, muddy streams actively demand their bottom and sides. As a return of increase canyons, are winding, in which on that point are terraces and another(prenominal) features of behave and vale shapes.\n\nWhere boggy flow rate falls, the vast ingathering of material transported by them, forming large(p)(p) alluvial fans, normally tie to the pass of the mouths of underwater canyons. fan adjoining canyons can blend to gether.\n\nAs a result, at the base of the Continental slope is form by a large pitch plains - the nigh distinctive structural bearing Mainland foot. The total subject matter of rainfall can make water several(prenominal) kilometers.\n\nOn the ledge the have establish of atomic number 1 ion and gravitational factors provides originally a handing over government natural action sedimentary material. In addition, the cosmos of subaqueous shelf ephemeral because the geomorphologic results accumulative hydrogen ion activity and gravitational factors and its restore on the topography of the shelf is limited.\n\nIn batialniy and abysmal zones of the ocean floor enduringness of these processes is glare than on the shelf, nevertheless the distance of action much more.
