Antarctica kanye nezokuvakasha - azihambelani?

Mainland eningizimu kakhulu Zomhlaba latholakala 1820. Isimo sezulu lapha inonya ubuncane kusho lokushisa air yonyaka. Yezimila nezilwane ezihlukahlukene zilinganiselwe, akukho labantu unomphela.

I Cruises ngowokuqala Antarctica ziye uzibophezele ngawo-1960, indawo izindiza - 1970s. Minyaka yonke inani ezivakashela nezwekazi enomoya emhlabeni, liyakhula. Ngo-2010, kwakunabamemezeli ababalelwa ku-40,000.

Izivakashi e-skiing Antarctica, snowshoeing ngisho yezikebhe, iziteshi ucwaningo ukuvakashelwa kanye lezinto zemvelo ezihlukahlukene. The main ezikhangayo Antarctica :

• Valley McMurdo (endaweni driest Emhlabeni) ;
• Igazi Falls ngesikhathi Taylor Glacier;
• isikebhe lushone "ulwandle olungenamkhawulo";
• Bouvet Island - yezindawo esiwugwadule kakhulu futhi akuthandeki Antarctica;
• Dronning Maud Land, nge Amashalofu okubeka yayo eminingi futhi abukhali enamadwala - nunataks;
• Ukukhohlisa Island - mlilo bangaphambili;
• olunothile ngokungavamile Strait Lemeyr;
• namandla Unas-Tits nabanye.

Ngokungangabazeki, elinye ezindaweni ezithakazelisayo kakhulu futhi bavakashela zaleli zwekazi - Igazi Falls. Antarctica nayo kakhulu zithanda ukuvakashela esiteshini ucwaningo.

Kulapha yiyona okuthiwa Igazi Falls. Ngo-Antarctica, indawo isithakazelo esikhulu, hhayi nje phakathi izivakashi kodwa futhi phakathi izazi zesayensi yezinto eziphilayo. Kwavela ukuthi kuleli qophelo, ngaphansi ungqimba imitha-400 ice, kungekho ukufinyelela kokukhanya nomoya, ama-bacterium ephila ngokuthula. Ukutholakala kwaleli qiniso wasiza ososayensi uthole okuningi izimpendulo, kodwa ngesikhathi esifanayo wabeka inqwaba nezindaba ezintsha.

Igazi Falls watholwa futhi esachazwa sokuma Griffith Taylor ngo-1911. Kubukeka ngempela umxhwele: inqwaba ukusakaza abomvu uvela ikholomu yeqhwa emhlophe. Umthombo waterfall kuyinto usawoti echibini komhlaba, embozwe kusukela phezulu ice pack. umbala Eyingqayizivele amanzi kuwo, ososayensi ukuchaza okuqukethwe eliphezulu yensimbi oxides.

Igazi Falls: ngamathiphu okuhamba

Ilitshe angavalelwa Taylor yeqhwa futhi lingaphakathi Dry izigodi McMurdo. Ukuvakasha kwakhe kungenzeka kuphela yizivakashi ngesikhathi sasehlobo Austral (November-February). Ngalesi sikhathi, umoya "iyazifudumeza" -5 ... -10 Celsius.

Esiseduzane Igazi Falls zitholakala Australia naseNew Zealand. Kuyinto ezivela kula mazwe iqala iningi izinkambo Antarctic ukuba lesi simangaliso zemvelo. Izivakashi Igazi Falls athwale esuka eNingizimu Afrika, Chile futhi Argentina. Isihambi uhambo enjalo izobiza isizumbulu semali ayizinkulungwane 300 abe ingxenye yesigidi ruble Russian.
