Kutheni snow ezimhlophe? thina sikuxelele

Umbuzo kutheni ikhephu kumhlophe, yinto eqhelekileyo kumntu wonke ukususela ebuntwaneni. Kodwa asingabo bonke abantwana, nabantu abadala abakwaziyo impendulo echanekileyo, ngasizathu sithile, lo snowflake encinane omhlophe kunokuba eblowu okanye eluhlaza. Wonke umntu uyazi ukuba ikhephu - kuba amanzi engumkhenkce, okanye mandithi ngumkhenkce. Kodwa njengokuba lo qhwa selubala kwaye banako ekudluliseleni ukukhanya kuyo, kutheni snowdrifts kwalowo emhlabeni, kude ngaphaya kwawo yaye umbala kakhulu?

Eminyaka edlulileyo, xa kungekho phuhliso ubugcisa ukufunda zonke iinkqubo zendalo, izazinzulu ziye zalwa umbuzo kutheni ikhephu emhlophe. Noko ke, kwafumaneka akukho mpendulo. Kuphela xa yonke inkqubo nokudalwa nekhephu ekuqaleni ukuya ekupheleni kwacaca, bekukho ngokufunisela malunga "kwiqweqwe emhlophe."

Yonke lento iqala nesibakala sokuba phantsi kwempembelelo ubushushu, amanzi ilanga imilambo, amachweba kunye neelwandle iguqulelwa kwi zomphunga liphakame kwiingcamba esesibhakabhakeni apho permafrost siyema. Le umphunga bona babe iimpawu zamanzi elulwelo, ngenxa iqondo elikhulu ezimbi uqalisa ngumkhenkce kwaye amathuba ziikristale omkhenkce. Esi snowflake, nto leyo eya ukulungele ekugqibeleni ziwe emhlabeni. Ubukhulu becala, kuloo ndawo apho kushushu, icicles kuwa imanzi imvula, linyibilike nkqu emoyeni.

Njengoko ikhephu imiswa, ngoku, kodwa ngenxa yesizathu esithile, xa uyawa emhlabeni, yena ngesiquphe uba emhlophe?

Lo mbuzo efanelekileyo, kuba iqhwa yaye inyaniso ayikho kuloo zezulu iimpawu flow efanayo ukukhanya kuyo, yaye lo qhwa. Kodwa asimele silibale enye into: ngohlangothi ilens kubekwe phantsi iikona umbhodamo ngokungakhethiyo refracts kwelanga, yaye musa ukukuqonda, udlule. Kwaye xa iqhwa ubuthe "njengekhephu-white isikhuselo," imitha yelanga likaThixo refracted yi snowflake enye kwenye, ukuba acande lonke isiciko. reyi abaninzi kubonakala emehlweni ethu, nto leyo esisizathu sokuba rhoqo, xa ujonga ekhephini, kufuneka squint. Kwelanga ukhanya kakhulu kwimbono kwamehlo akhe engakhuselekanga.

Kodwa akukho kakhulu oluchanekileyo ukubuza umbuzo kutheni ikhephu kumhlophe, kuba akusoloko "uhlambulukile". Ngoko abantu babone oko kuphela xa imitha yelanga kuwa phezu kwayo. Ngokomzekelo, ukutshona kwelanga oko zipeyintwe nombala bomvu, kwaye ukukhanya kwesibane etyheli inokuba kancinane intlabathi-bala, kwakunye ngemini enamafu yinto ithinti nombala.

Ukutshintsha umbala kwekhephu nangoku kwiingcamba emoyeni, xa iqhwa kuqala nje zabo "umhlaba kokuwa." Umzekelo, nomungu ezahlukeneyo ukusuka imithi kunye neentyatyambo, nothuli kobuntu umhlaba owomileyo kwaye uyakufezekisa inabe nekhephu airflows. Ukuba oku kufuneka ixesha ukunyibilika ikhephu, wawasindisa kuligquma encinane, nakanjani ukuba umbala shades ezahlukeneyo. Kwezi meko, ukubuza isizathu sokuba ikhephu omhlophe, akufanelekanga.

Noko ke, iqhwa - nto bendiza elingafani phantsi icicles, nto leyo ngenxa yezizathu ezingaziwayo, wagqiba kwelokuba yokugubungela phantsi "isigqubuthelo white".

Iimpawu eziphambili ikhephu - oku ukukhusela umhlaba abanomkhuhlane, wambu ngengubo zamafu. Ewe, kushushu kwaye ugcine isityalo kunye umhlaba ebandayo, kubonakala ngamazwi, kodwa yinyaniso. It has conductivity amahlwempu thermal, nto leyo evumela ukuba awuthintele ubushushu ophuma emhlabeni, kwaye ukudala "ababetheki thermal". Akumangalisi ukuba wakha abahlali Igloo eFar North. Umkhenkce, ikhephu, yayigcinwa ishushu kakuhle, ukudala iimeko ezizodwa ubomi.

Thina kufuneka singalahlekani nento yokuba ubukhulu iqhwa kuxhomekeka kwiimeko zemozulu ngaphandle. Ukuba kuyabanda ngokwaneleyo, amasuntswana umkhenkce mincinane, phantse imperceptible. Ke ukuba ilanga likhanya yaye umoya obandayo kunjalo, ubukhulu iqhwa ungaba kuze ngokweesentimitha eziliqela. Ngoko ke, ngo-1944, wawa desyatisantimetrovyh "zamani omkhenkce" eMoscow.
