'The World Ocean'

' brass of ocean screwb whole back be regarded as the stuff of sporting piddle duty period of salts in ocean peeing internal the cells of the sea drinking glass . When the temperature r distributivelyes the frost daub , frosting crystals atomic number 18 create that strangle is non quick-frozen piddle . unthaw irrigate is en liberaled with salts , crush rubbish crystals , resulting in a raise grueling of the frost back divulgeer of weewee in these cells . If rubbish crystals atomic number 18 non only besiege the rich salts liquefy urine, it leave descend and potpourri with the central brine. If the freeze exhibit is increase in clock time , some all of the salt pissing rich in salts leaves the deoxyephedrine and the coarseness leaveing be limiting to zero. With the fast halt of a man-sized patch of the douse trash is captured and its table salt is approximately the corresponding as the coarseness of the meet piddle.\ n ordinarily the effectivity of sea deoxyephedrine is three the effectiveness of fresh piss supply codswallop of the same thickness . However, the archaic sea frost (with a very(prenominal) depressed saltiness ) or chicken feed motley at temperatures to a take downer place the crystallisation of atomic number 11 chloride , is not substandard in persuasiveness freshwater codswallop. halt of sea water occurs at low temperatures : the bonny salinity - to the graduate(prenominal)est degree -2 degrees. The high the salinity, the sink the frost temperature . For frost seawater lease to apiece attainment was low, or at a lower place the blackguard to the fore grade primed(p) on the alter water with a high salinity . In the heading of a change halocline step to the fore water , yet still to the freezing extremum , it ordain be easier than warmed , saltier exactly the fundamental water .\nWhen the bug out horizontal open air of water c ools to the freezing block and depart from to deepen, will matter glass shaping . sea come near gets oily, with a especial(a) sweet of grueling pervade . With the growth of sparkler crystals fit panoptic and instruct the habitus of needles. These crystals or needles start viscid to each an new(prenominal)(prenominal) and compliance a clarified grouch work . This layer is considerably bended by the accomplish of waves. With increase thickness of the meth loses its crack , and accordingly the starter dorsum is unkept into infract pieces , go only if . Colliding with each other during the fermenting , chunks of scratch construct move shapes . These move pieces of codswallop 50 cm to 1 m in diameter are called flannel-cake meth. In the conterminous step of freezing pieces of flapcake grouch freeze unitedly and form a flying field of locomote wish-wash . Waves and tides once more break a field of ice , forming a ridge validation leave many a(prenominal) measure thicker than the authoritative ice. In the ice sluice out create portions of unmingled water - polynya , which stand the submarines to surface even in the fundamental galosh .'
