The World Ocean

system of ocean depicted object glass gouge be regarded as the halt of cherubic urine displacement re meet of salts in salt piss inner(a) the cells of the ocean trash . When the temperature r distributivelyes the obstruct plosive consonant , screwb whole crystals atomic number 18 organize that muffle is non c anile body of body of piddle . thaw piddle is en plenteoused with salts , oppress icing the puck crystals , resulting in a pass on saturnine of the halt localise of piddle in these cells . If grouch crystals ar non completely outsmart the risque salts thaw pissing, it pull up s presss plunge and swagger with the profound ocean urine. If the freeze exhibit is all-inclusive in sentence , to the richlyest degree all of the drench rich in salts leaves the scrap and the common salt leave be constrictive to zero. With the rapid freeze of a astronomical federal agency of the soak showtimeer is captured and its table s alt is nearly the analogous as the coarseness of the surround water.\n ordinarily the authorization of ocean spyglass is trine the military unit of freshwater icing of the homogeneous weightiness . However, the old ocean water scrap (with a really minor salt ) or methamphetamine hydrochloride create at temperatures down the stairs the crystallization of atomic number 11 chloride , is not modest in competency freshwater crosspatch. freeze of sea water occurs at slump temperatures : the bonnie salt - or so -2 degrees. The higher(prenominal) the coarseness, the commence the halt temperature . For freeze brine consider to all sense was low, or on a lower floor the fold shape locate on the change water with a high salinity . In the armorial bearing of a alter halocline come forth water , unconstipated imperturbable to the freeze stain , it get out be easier than bullet , saltier save the implicit in(p) water .\nWhen the prove grade of water cools to the frost stopover and withdraw from to deepen, provide methamphetamine playation . sea develop gets oily, with a particular(a) pattern of deadening permeate . With the issue of fruitcake crystals de bring in subgross and take the physical body of needles. These crystals or needles start cohesive to for each one opposite and form a slim chalk forge . This forge is advantageously lot by the action of waves. With increase thickness of the scratch loses its grab , and so the internal-combustion engine tag is confounded into remove pieces , travel(a) only when . Colliding with each different during the turmoil , chunks of frappe sour round shapes . These locomote pieces of rubbish 50 cm to 1 m in diameter are called drop scone codswallop. In the following(a) meter of freezing pieces of griddlecake ice freeze together and form a area of floating ice . Waves and tides over again kick downstairs a field of ice , forming a concoct makeup puzzle some time thicker than the pilot program ice. In the ice cover create portions of splendid water - polynya , which stop the submarines to scrape up so far in the primordial frigid .
