Yintoni umgca snow na? Ukuphakama kumgca ikhephu kwi ezinezinga ezahlukeneyo Earth

I ephakamileyo enyuka ezintabeni - ezibandayo iba. Le nyaniso ukufunda esikolweni. Ukuba ufumana ezintabeni liphezulu kakhulu, uyakwazi ukubona ikhephu ukuba unyaka wonke apho.

Kweli nqaku siza kuthetha ntoni umgca ikhephu elo. Yaye ngoko kungenxa kwaye imisela ukuphakama kwayo nayo.

Yintoni umgca snow na? le nkcazelo

Ngenxa yokwanda-up for 100 yonke kwiimitha liyancipha lobushushu zezulu degrees 0.6. A ubungakanani ehlukanisiwe kwezulu, ngokulandelelanayo, kwandisa. Undizela phezulu, baya kuwa njengekhephu. Kwindalo, kukho kwinqanaba elithile apha ngasentla iintaba bekhephu akuthethi kunyibilika konke konke. Yaba bakhe waza wabiza umgca ikhephu i (okanye amazwe).

Le ukutyhilwa lula kakhulu kota. Yintoni umgca ikhephu yangqinelana indawo umbono benzululwazi? Le Isazinzulu ezaziwayo-kakuhle MV Lomonosov ebizwa "maleko frosty ye emoyeni." Yayo Hi ndlela leyi, nguye lowo lamiswa ukuba umgca ikhephu le ezintabeni ukuphakama kwayo ixhomekeke ubukhulu becala ngama.

Ngoko ke, phantsi umgca ikhephu kwe ukuthini umda aqhelekileyo emhlabeni ngasentla apho ekufumbekeni komoya kwifomu esiqinileyo uyawongamela yokunyibilika zabo. Le umda njani ngokucacileyo photo ngezantsi:

Izazinzulu ziye ichonge iintlobo kumgca ikhephu:

• senkolelo;
• zendawo;
• lonyaka.

Ukongeza, lomhlathi, kukho into enjalo njenge "kwinqanaba 365". Lo mda isezantsi ngaphakathi kuyo ikhephu ubuxoki unyaka wonke kwaye akukho anyibilike.

Yintoni egqibayo ukuphakama umgca snow na?

Kutheni kwezinye umhlaba iindawo ikhephu alele ezantsi nje, kunye nezinye - luquka eqhelekileyo "cap" kuphela ziphakamileyo? Ziziphi intaba udlula phezu komgca ikhephu, kwaye apho - ngezantsi? Yaye kutheni?

Impendulo kuyo yonke le mibuzo kodwa wafumana Lomonosov. Isizathu esiyintloko ubude ezahlukeneyo kumgca ikhephu le - le inkululeko iindawo. Le theyibhile ilandelayo ibonisa ixabiso ahanjiswa yale parameter njengomsebenzi anenkululeko.

Amaqanda kwizihlalo zokugqibela ezintathu (kwikholam ye-Southern saseNtla) kufuneka sifake umfundi baxakwe. Kuyinto la ezinezinga i "ifriji" inkulu iplanethi yethu - ilizwekazi Antarctica.

Ukuphakama umgca ikhephu kwanjalo ixhomekeke kwezinye izinto, zemozulu orographic. Umzekelo, oku parameter kuchaphazela kwezulu ngonyaka kwaye mphandle kunye kufutshane olwandle. Ukuphakama umda ikhephu kuxhomekeke ekubeni ethambekeni ethile. Umzekelo, kwi northern (mnyama) icala kummango kuya kuba ngaphantsi kakhulu kunokuba emzantsi (sunny).

Kwenzeka ntoni nge ikhephu ezintabeni?

Ukuba phezulu ikhephu ezintabeni linyibilike kwaye oqokelela, ngoko akazange aye phi? Ukuba sithi ngasentla komgca ikhephu amathontsi kwekhephu okuninzi ngaphezu onokunyibilikisa, ngoko kangangamawaka eminyaka kukho anemfumba ezininzi imvula eqinileyo! Nangona kunjalo, oku kungenzeki. Kutheni?

Inyaniso kukuba ikhephu, kunjalo, iwela ezantsi. Nokuba phantsi amandla womxhuzulane, okanye yintshukumo imisebenzi umoya. Ngenxa yoko, iinkozo ikhephu ukukhanya babanjwa nomoya phantsi endulini, apho linyibilike kancinane xa zidibene nelanga jikisa ekuthiwa firn. Ngaphezu koko, le ngobuninzi ikhephu-ezifana uqhubekela phantsi, ukutshintsha ubume babo. Firn ngokuthe ngcembe iba eliqhubayo okuhambe glacier ice. Ngoko ke wazalwa glacier intaba.

Kubalulekile ukuqaphela ukuba akukho zonke iintaba igalelo kuphuhliso ice baseRoma. Kukho kwakhona isiqabu obalulekileyo ntsimi. Kuba ukuyilwa kwentaba glacier yinxalenye kufuneka ibekhona kwi kumathambeka wemigodi ezibanzi yaye zinzulu, nto leyo eba firn.

Ekuphetheni ...

Yintoni umgca snow na? Ngamagama alula, oko umda ngaphaya apho kukho ikhephu unyaka wonke. Ukuphakama umgca ikhephu i kwiingingqi ezahlukeneyo zomhlaba ayikho iyunifomu. Ngoko, kwi-South Pole oku kulingana kumgangatho wolwandle, kwaye ngomhla we Tibetan Plateau lisingisa phantse ezisixhenxe leekhilomitha. Ngokubanzi, apha kukho ulawulo olungqongqo; ukusondela nezibonda zehlabathi, ukuphakama komgca ikhephu iya kuba ngaphantsi.
