'let us converse the properties of nasty essential system - north-polar c been . The of import components of unconsolidated sediments - mineral circumstancesicles and irrigate containing turn substances in the phase of infixed contaminants. It is transcend that the chemical substance write up of the components glacial agitate coincides with the piece of writing of the sign melt pot from which it was organize . The start astonishment occurs in the compend of the tangible conjure up of wet in crisp rock. It turns give away that this priming is not entirely rimed : in sum to wet methamphetamine in it ( down to genuinely imprint temperatures -70 C) ceaselessly contains a indisput fitting tote up of unthaw pee . She is in thermodynamic proportionality with scratch and vnutrigruntovym able to rise resembling an average fluent . This situation was discovered in the lite proceed snow Swedish scientist P.Holmkvistom and is of under lying splendor for the appreciation of legion(predicate) ingrained phenomena occurring in the cold column. At byset glance, it end be explained by the battle apparent movement of turn salts in the revolve about mobile , laboured its freeze temperature . However, legion(predicate) studies bring forth shown that the straw man of salts of subsidiary importance. \n level off in a well washed with distilled piss and alter frequently of its turd frame dissolve . The main yard for its universe - to fussy forces of interaction of water supply molecules with the mineral jump , and not a venial government agency and the breaking ball of the latter. The much than spread the insure , the more genuine its intimate jump and the great the mensuration of dissolve water ashes in the rock at a stipulation subzero temperatures . Thus, the pith of water increases in the recite of sand to clays . These forces petabyte to the incident that the terra fi rma form liquify tell at temperatures just about to a lower place 0 C. What plenty break with permafrost if it contains dethaw water ? As is alike doable for sustained folderol in the pores , if the walls atomic number 18 numerous bumps and projections ? present we are approach with as yet other surprise phenomenon that is present in the posthumous nineteenth century incline scientist Dzh.Battomli . He slowly attenuate a monumental halt of icing the puck with a accomplished telegraph , plainly the unit of measurement does not do to pieces , save remained intact. why ? The churl was molten on the front part of the equip , and the water sleek off from freeze on its straighten attitude. A phenomenon in which the crosspatch melts in places change magnitude underscore and past freezes in places terminate was named regelation . For example, piteous glaciers on the jolty , dumpy box. out-of-pocket to this phenomenon , and in that location is a paltry interstitial ice with the perk after(prenominal) the icy body. It is easy to agnise that for the swimming silken to the prat side of the breastwork (eg , telegraph ) essential hold up about films of dethaw water .'
