Izintaba Transantarctic: indawo, izici ekwakhekeni, amaqiniso athakazelisayo

Transantarctic Izintaba Uyi kumiswa esiyingqayizivele yemvelo, okuyinto "unqamula" lase-Antarctica ibe izingxenye eziningana ukungalingani. Isimo sezwe libhekene ngokuchichima iphakama nezigodi enamadwala. Transantarctic Izintaba - indawo ocebile kakhulu nemibukiso wezinsalela zamandulo. Ngakho-ke, lokhu yokhalo phakathi abacwaningi emkhakheni paleontology is hhayi kuphela ngokuthi "Dinosaur Museum" ezaziwayo.

Umlando omfishane

Trans yokhalo yaqale ezaphawula ebalazweni British wamazwe iJames Ross e 1841. Nokho iphayona behluleka ukufinyelela unyawo iziqongo wendawo. e kuphela 1908 Scott eviyweni, uShackleton Amundsen sawela ugema ngesikhathi uhambo olude, okuhloswe ngaso ekuzuzweni kwemiPhumela-South Pole.

Ukuyitadisha ngokucophelela le ncwadi i-Transantarctic Izintaba kwenzeka ngo-1947. Ngenxa yale njongo uhambo olukhethekile elalihlelwe ngayo, wabizwa ngokuthi "gxuma okuphezulu". Isimo sezwe wahlolwa izindiza. Ngenxa yalokho, abacwaningi baye bakwazi ukwenza amabalazwe ngokwanele ezinemininingwane yesifunda.

Baphi Transantarctic Mountains?

Uhlelo lwezinkalo kwakhiwa emadwaleni enamadwala, ibanga ayizinkulungwane eziningana amakhilomitha kusuka Sea Weddell ukuze Obumavukuvuku Land. Lena ngenye yama-isikhathi eside izintaba zokhahlamba emhlabeni.

On lokho izwekazi kukhona Transantarctic Mountains? Zokuma kwendawo cabanga yokhalo umugqa ezivamile ehlukanisa eMpumalanga naseNtshonalanga Antarctica. At ibanga cishe 480 km kusuka lolu chungechunge amatshe iyona-South Pole.

nokwakheka

Ngomqondo Geological Transantarctic Izintaba kwabonwa njengentfo okukhipha ezinkulu uqweqwe phezu kwalokho kwamiswa ngenxa umsebenzi asebenzayo zokuzamazama komhlaba iminyaka eyizigidi ezingu-65 edlule. Okunye amabanga, okuyinto zitholakala ngaphakathi kwemingcele Antarctica, kukhona okuningi umsuka yamuva.

Liyini iphuzu eliphakeme? izintaba Transantarctic zifinyelela ubude obungamamitha 4528 m ngaphezu kogu lolwandle e-isigaba osesikhundleni Kirk-Patrick. Imali idwala lokhu kumiswa bagxila inombolo enkulu zamathambo kule lonke uhla. Amashumi ezigidi eminyakeni iwukuhlale i isimo sezulu eliphezulu ukuphila nokuthuthukiswa eziphilayo, lokho empeleni kuchaza emakamu eliphezulu izinsalela zabo zohlobo.

amaqiniso ezithakazelisayo

Kunezindlela eziningana amaphuzu ezithakazelisayo ngomlando isifundo Transantarctic Range:

1. Phakathi nekhulu leminyaka eledlule kusukela ice wendawo alishiye yeqhwa emikhulu kunayo yonke eyake irekhodwe ngalokuhlelekile abacwaningi. endaweni yaso 31 080 km, eyeqa insimu ka kwamanye amazwe aseYurophu.
2. Transantarctic Izintaba, ikakhulukazi, endaweni yabo okuthiwa McMurdo, izindawo ezomile kakhulu kule planethi, lapho kungekho imvula ngoba kuka 2 million eminyakeni.
3. Esikhathini okuthiwa Taylor Valley, oyingxenye ye umbono zokhahlamba, kukhona Waterfall, lapho imifudlana phansi imibala abomvu. Okunjalo into nabacwaningi ukugcwaliswa umsebenzi amanzi lomkhiqizo amagciwane anaerobic.
4. Ukwakheka ukuthi kuyingxenye intaba ephakeme kunazo zonke ye-bulala Kirk-Patrick, phakathi nekhulu leminyaka eledlule, izinsalela dinosaur ezinamaphiko atholakele. Ubukhulu ilingana usayizi wathi wezinsalela zamandulo iqhude elikhulu. Eduze le ndawo ikhishwe izinsalela zamathambo Cryolophosaurus - encane dinosaur ezidla.
5. Kwelinye amaphuzu okwedlulele ugema - Cape Adair ahlelwe eqhugwaneni esakhiwe edume iphayona Norwegian Carsten Borchgrevink. Nguye e-1895, ngaphambi kokuba abanye abacwaningi owalubhada lase-Antarctica. Buildings kahle walondoloza kube sesikhathini samanje, ngenxa okushisa aphansi kakhulu ezenzeka esifundeni.

Ekuphetheni

Trans-Antarctic Ridge uhlala kwenye yezindawo okungenani uhlole emhlabeni kuze kube namuhla. Ugxeka remoteness kakhulu into engokwemvelo impucuko enkulu, kanye izimo ezinzima zezulu. Ngesikhathi esifanayo ugema kuyinto ubuhle kumnandi lendawo, okusikhumbuza namathafa kusuka kwamanye amaplanethi.
