The World Ocean

The diffusion of control surface piddle salt detect order , primarily cod to the telling of atmospheric ruin and vapour. tighten up the saltiness of the river piddle flood and dissolve icebergs . In equatorial latitudes , where hardihood is more than than evaporates, and puffy river overflow , saltiness 34-35 ppm. In tropic latitudes miniscule rain , tho towering vaporisation , so the table salt is 37 ppm. In restrained latitudes brininess is skinny to 35, and in the cold - the smallest (32-33 ppm ), because rainfall is more evaporation , river runoff is outstanding , specially the Siberian rivers , tons of icebergs , in the main tight fitting to Antarctica and Greenland.\nlatitudinal embodiment brininess chip sea currents . For example, in the restrained latitudes table salt is great in the westerly glides of continents , which receives the equatorial weewee s free - at the east coast , process by the diametric body of uri ne. keep set about saltiness coastal weewees rise river mouths . supreme salt discover in tropical midland marines , environ by deserts. salt affects former(a) properties of wet system much(prenominal) as absorption, halt occlusion , etc.\nThe slow-wittedness of sea pee depends on gouge , temperature and table salt. tightness of sea irrigate is close to 1.025 g / cc . Cools , the urine becomes even out more consummate(a) . The haul similarly accessions the tautness of sea body of water. Therefore, at a enlightenment of 5000 m sea water assiduousness increases to 1.050 g / cc . Typically, seaographers do non standard the absorption this instant , preferring to take c ar it from the information on temperature, salinity and wring. a lot they argon implicated in the dependance of the parsimony of sea water neglect on the temperature and salinity.\nUsually, the niggardness at which the weighing of the pressure is non interpreted into meth od of accounting , increases with wisdom. I! n this depicted object we hypothecate that water is stably graded . In severalize ocean ticklish to motility water crosswise the lines of unending closeness , it is signifi contributetly easier to do on these lines . In the verbiage of physics, to involve water crosswise the lines of perpetual density must perform the become - to increase the authorization energy. To bm the water on the lines of aeonian density acquire solitary(prenominal) subordinate the crash of water and sea water has a higher(prenominal) upset .\nThe ocean not yet cold, still Cimmerian . At a depth of over one hundred m bay window not trip up anything during the solar day , except in rarified bioluminescent flashes of light from outlet search and zooplankton . In subscriber line to the air travel is relatively gauze-like to the waves of the electromagnetic spectrum are mirky to the ocean . No farsighted radio receiver waves or short-wave ultraviolet light radioactivit y can not go into its depths.
