Pack chando: features, achiumba, kuparadzirwa

Pack Ice uri akasiyana nemamwe dzinongoitika chinoshamisa. Zvinonzi vakachengeta chete kuchamhembe latitudes iri nyika, mune kweArctic mudunhu. Kana izwi rinoshandiswa zvachose vose kukukurwa chando, asi pashure zvidzidzo akawanda packs it ari oga boka. Vane zvinoverengeka zvivako kuti kusiyanisa kubva mamwe marudzi chando. Tsanangudzo "ice-gore Multi" kwakafanana, saka chinoitika pamusoro chete maitikiro mukati.

Zviri rongedza echando

Arctic vatsvakurudzi, vezvikepe uye vafambi akambova kushanyira ari kuchamhembe latitudes, vanonyatsoziva kuti kwakadaro rongedza chando. Fani iyi kunounza dambudziko kune vakundi kurutivi rwokumusoro.

Izvi Ice vasakukurwa mugungwa, uremu hwavo rakakura, uye arambe achirema chaizvo. Netsaona kudhumhana kunogona kukonzera wandei kukuvara kunyange mudziyo kupfuura ano. Pack chando zvakasiyana muupenyu ehupfumi dzavo. Maererano nenyanzvi, rongedza aumba kubva mvura mugungwa, Ukobvu mukuru mamita 3. Zviri denser pane zvavo chando nokuda zvikuru yakaderera munyu kugutsikana.

Muitiro rokuumba rongedza echando

Ice achiumbwa kuchamhembe latitudes yakaderera tembiricha. Kana mvura gungwa yaita chando, pane nedanho desalination, mvura nguva dzose rave thawed salinity pamwero kudzika kupfuura pakutanga. Ichi chinhu chinowanika packs it, ndiyo dzinotsanagura nechando uye thawing kanoverengeka.

mvura Sea chinozadzwa chando, zvichiumba icebergs uye guru chando floes. Zvadaro, kubva guru chando floes arrays zviduku vari akochonorwa, zvizhinji zvacho zviri ipapo dzikwanise packs it. Havana kuzivikanwa zvimwe zviri siyana. Pane zvakasiyana-siyana packs it: kubva sandara chando floes kuti yakakura boulders, chirefu pamusoro pegungwa.

Vaongorori vakawana kuti, vasati nechikepe, rongedza chando runosvika kweinenge 2 Zvinonzi nechando uye razmerzaniya wepagore. Uye uyu anokonzerwa zvayo yakakwirira arambe achirema uye vakaderera salinity. Chokwadi chokuti thawing uye apiwa kuoma nechando munyu mvura inodonha mugungwa. Vakwasvi vanoziva kuti yekare rongedza chando kunyange yakanakira mvura yakachena, apo unogona kugadzira zvokudya.

Nzvimbo "dzinogarisana"

Vakagovera rongedza chando kweArctic Ocean. In rwezasi nyika, nyika Antarctic nharaunda, havasi kudaro mune mumwe munyanza havasi kuitika. Mukuru arambe achirema uye nezvimwewo trajectory vasakukurwa zvingatitadzisa kufamba kunyange simba zvikuru zvenyukireya dzinopwanya aizi. It iri chikonzero akabvunza pakati nzira Bering Strait uye Murmansk haasi kuburikidza yakakwirira latitudes (North Pole), uye pamwe kuchamhembe pemhenderekedzo kondinendi. Mukuru-mwero pfupi nokuda yechitatu, asi kufamba rongedza echando zvinoita kuoma. Naizvozvo, kuti nezvifambiso kutaurirana nguva dzose haina kushandiswa. Chokwadi, pane ngarava dzakawanda kuti vakapfuura nzira iyi yakaoma. Nyanzvi kuziva kuti zvinokwanisika ichipfuurapo, kunyanya pasi perekedza yacho aizi. Asi kugara voli kuti nguva yokuva haina kuitwa.
