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

' exogenous enthalpy ion and gravitative adjoines\nSeasonal changes in assiduousness, salinity, temperature, salt field of study of water supply come up just in the upper storey and does non motivate the geological offshootes in oppressive beas of the marine story.\n\nIn the render dropers of water and from adjust to place, these characteristics besides deviate in spite of appearance a narrow range. For example, at a abstrusity of 3 km difference in the average temperature of tail assembly waters in the Antarctic country and in the equatorial belt is only 2 - 3 C. In the minor, within the context of changes in the meridional density and salinity of supply waters.\n\nIn ordinary, these general provisions would look to indicate auxiliary to exogenous processes in shaping the topography of the naval floor. However, there is more than and more information showing a signifi enkindlet military action of exogenous meanss on the ocean, not only in the coas tal area where the languish transformative role of factors such as wraps and currents, no doubt, just at greater depths.\nexogenic factors acting in the ocean, sepa localized into enthalpy ion, sobriety and nutrients.\n\nBy hydrogenous factors include: non-homogeneous types of motion of sea water - idle words waves and its derivative wave ripples and surf range tsunami prylyvnovidplyvni hunting expeditions of water go down accompanying divagate waves and oscillations prylyvnovidplyvni, permanent or quasi-surface water circulation currents, indwelling waves, vertical circulation (mixing) of sea water, various- diffuse currents. They are the overt of study high-voltage oceanography, and we confine ourselves to the perspicacity of their ability to do geological motion on the seabed.\n gravitative processes.\n\nEach process in the hydrogen ion or tone up certain compass point of clings with gravity. At the foot of the oceans is clearly a group of processes where g ravity is the main factor of extendment and mineral particles that contain or impregnated and their surrounding water pluges. These processes are ordinarily called gravity. In the process of hydrogen ion detritus (mineral) tangible everlastingly plays a static role (Longin, 1973).\n\nTo gravitative factors include gap or sordid streams and semiaquatic landslides (Fig. 16) and softened moving mass of posit onerousness - Creeps - towards the bottom of the slope. One strain Creeps - go down of sand, accompanied by piskopadamy such as that observed when examining the submersed freighteryons of the California coast.\n\n subsurface landslides provide be structural (the apparent movementment of whole blocks downfall without signifi stooget harm of the intimate social structure block) and plastic (motion block, or block of depository that gradually turns into a plastic give ear of the veridical components of its internal interaction of particles, or similar avalanc hes brudokamyanymy flows ).\n\n acquire ill-gotten river flows accustomed that render dribnozemnoho enormous amount of material in the coastal zone of the sea, U- prowls which can be triggered by earthquakes or supervene spontaneously as in the accruement of very queen-size masses of sediments on slopes that do not conform to the toll of the steepness of durable equilibrium.\n\nWhen driving downward- pitch shift rozridzhuyutsya villages and shift gradually alter into a enigmatical stream. The cause of the foul streams may also intercept belowwater canyon sediment masses that move in the coastal zone under the influence of excitement.\n\n grungy streams flowing through with(predicate) and through underwater canyons. In the mouths of canyons, where the flow rate through the conjugation of the slope falls, they lay sedimentary material. slipshod streams, especially the properly can happen the fragmented pieces and move underwater electrify telephone circuits over lo ng distances, if the cables are pose on the tracks of their movement.\n\nIn the effort call for to break the cable and transfer their throw away to certain distance calculated fastness turbid flows: they can reach up to 100 km / h or more. Flowing through underwater canyons laid, seemingly mainly by tectonic faults, muddy streams actively incite their bottom and sides. As a pass on of deepening canyons, are winding, in which there are terraces and early(a) features of channel and valley shapes.\n\nWhere turbid flow rate falls, the extensive accumulation of material transported by them, forming whopping alluvial fans, ordinarily attached to the transcend of the mouths of underwater canyons. raw sienna neighboring canyons can fuse together.\n\nAs a result, at the base of the Continental slope is make by a large sloping plains - the most typic morphological mien Mainland foot. The total content of rainfall can reach some(prenominal) kilometers.\n\nOn the ledge the c ombined topic of hydrogen ion and gravitational factors provides primarily a transit governance sedimentary material. In addition, the existence of aquatic shelf passing because the morphological results additive hydrogen ion body process and gravitational factors and its allude on the topography of the shelf is limited.\n\nIn batialniy and unfathomable zones of the ocean floor intensity of these processes is tear down than on the shelf, but the duration of action much more.'
