I-Antarctica: isimo sezulu nesintu

I-Antarctica yizwekazi lesithupha, eligcina lamazwekazi avulekile. Ngenxa yezimo ezinzima kakhulu ayitholakali kuningi. Noma kunjalo, abantu lapha abazami ngokukhethekile. Sekuyisikhathi eside, abacwaningi abaqeqeshiwe kuphela abangakwazi ukumelana nalokhu. Iziphepho zomoya, amazinga okushisa aphansi, ama-expanses angenamkhawulo weqhwa neqhwa - yilokho i-Antarctica. Isimo sezwekazikazi ikakhulukazi ngenxa yendawo yezwekazi.

Beka kwi-Globe

Isikhundla se-Antarctica yisona sizathu sokuthi sifihliwe isikhathi eside kusukela emehlweni abanobuciko bezilwandle. Izwekazikazi lesithupha liseningizimu yeNyakatho yeNhlaba, esifundeni se-polar. Ngaphandle kwebanga, kusuka kwamanye amazwekazi lihlukaniswa neqhwa elikhuphukayo, okwakuyimikhumbi yamakhulu eminyaka adlule kwaba yisithiyo esingenakunqotshwa.

Ngebanga elithile ukusuka enkabeni yezwekazi yiSouth Pole. Isiqu sokungatholakali okufinyelelekayo kanye nesimo esibi sokubanda ngamaphuzu amabili amanye ama-Antarctica angaziqhayisa. Isimo sezulukazikazi ngezwi jikelele livele licacile ngamagama abo.

Ukushisa

Uphawu oluphansi kunawo wonke, lapho ikholomu ye-thermometer ehla e-Antarctica, yi -89.2 ºС. Le lokushisa yabhalwa endaweni yesiteshi soSoviet ngaleso sikhathi "Vostok". Nasi isibalo esiphezulu sebandayo.

Ezindaweni ezisemaphandleni yezwekazi, azikho amazinga okushisa okuhle ngisho nasezinyangeni ezincane zasehlobo. Kusukela ngoNovemba kuya kuFebruwari, lapho isikhathi esifudumele sifike eNingizimu Yezwe Elithile , umoya ungafudumala kufika ku -30 ºС noma -20 ºС. Egwini, isimo sihlukile. Lapha izinga lokushisa ezinyangeni zasehlobo likhuphukela ku-0 ºС futhi ngezinye izikhathi liphakeme nakakhulu.

Kusha, kodwa kubanda

Izici zesimo sezulu sase-Antarctica zihlotshaniswa nesamba esikhulu samandla esivela esikhanyeni sethu, futhi ngesikhathi esifanayo izinga lokushisa eliphansi. Lokhu kungavumelani ngenxa yokubonakaliswa okukhulu kweqhwa. Ilanga ezinyangeni ezincane zasehlobo likhanya kusuka esibhakabhakeni esingafihli cishe kungabi yi-stop. Noma kunjalo, ingxenye ebandayo yokushisa ibonakala. Ngaphezu kwalokho, phakathi nobusuku be-polar, ehlala izinyanga eziyisithupha kuleli zwekazi, i-Antarctica ihlaziye nakakhulu.

Iziphepho

Ukuqina kwesimo sezulu se-Antarctica kuchazwa futhi ngesici sayo esisodwa. Lapha ukushaya okuthiwa i-kabatic, noma i-stock, imimoya. Zakhiwe ngenxa yokuhluka kwamanzi okushisa okuphezulu nomoya. Futhi isizathu sokwakheka kwemimoya ukucushwa kwamandla e-continental ice shield. Ubuningi bomhlaba obunamanzi bubuthwa, ubukhulu bawo buyanda futhi, ngaphansi kwesenzo sokuvuthwa komzimba, kugeleza kuya ogwini. Ubukhulu besisindo esinjalo buphakathi kwamamitha angu 200-300. Lithwala uthuli oluningi lweqhwa, okubuhlungu kakhulu ukubonakala endaweni eseduze nomoya.

Ijubane lokuhamba kwemimoya yomoya lixhomeke ekujuleni kwentaba. Imimoya enamandla kunazo zonke ihlangene eduze nogu lolwandle. Bashayela isikhathi eside. Ubusika base-Arctic yisikhathi samandla amakhulu, okuvela ngo-Ephreli kuya kuNovemba cishe ngaphandle kokuphazanyiswa. Kusukela ngoNovemba kuya ku-Mashi isimo sithuthukisa ngandlela-thile. Imimoya ivela kuphela lapho ilanga liphansi phansi, futhi ebusuku. Lapho kufika ihlobo ngenxa yokukhuphuka kwamazinga okushisa ogwini kuthula.

I-Antarctica, isimo sezulu kanye nezinyanga zasehlotsheni ezinzima kakhulu, ngenxa yokuqhutshwa kweziphepho zomoya ezinyangeni eziyisishiyagalombili azitholakali izindiza nezinye izindiza. Abahloli bama-polar, abaqashayo nge-hibernating ngalesi sikhathi, empeleni bahlale benqunywa ezweni langaphandle.

"Abantu bomdabu"

Isimo sezulu esinzima ngaleso sikhathi asizange senze i-Antarctica ingabi nendawo. Kunezinyoni, izinambuzane, izilwane ezincelisayo kanye nezitshalo. Lezi zinsuku zibhekiswe ikakhulukazi ngama-lichen nezitshalo ezikhula kancane (ezingekho ngaphezu kwamentimitha eyodwa). Ezwenikazikazi kukhona namasos.

E-Antarctica, ayikho enye yezilwane ezincelisayo ezisemhlabeni ngokuphelele. Isizathu salokhu sisezitshalweni ezincane: ezindaweni eziphakathi kwezwekazi, akukho lutho lokudla. Isilwane esidumile kunazo zonke kuleli zwekazi yi-penguin. Nazi izinhlobo eziningana zezidleke. Abanye bahlala kuphela eziqhingini, abanye bakhetha ugu.

I-Antarctica, isimo sayo sezulu esonakalisa izilwane eziningi, ayinqamuli izibindi, kanye nemikhomo eluhlaza okwesibhakabhaka, imifino yamademoni, izintambo ezibulalayo, ama-whale angaseningizimu. Ezinyoni, ngaphandle kwama-penguin, ama-expanses anesibhakabhaka ayedabulela ama-skuas nezimpungushe.

Isimo esinzima sezulu sase-Antarctic asifaneleki kubantu. Noma kunjalo, lokhu akuvimbeli ososayensi ukuba bahlolisise leli zwekazi ngenkuthalo: kukhona kakade inombolo enkulu yeziteshi ze-polar endaweni yayo. Abacwaningi minyaka yonke balwela ukunqoba izimo ezimbi kakhulu, ukufihla izimfihlo eziningi zezwekazi kanye nemvelo ngokujwayelekile.
