Transantarctic Mountains - meel aad buu hodan u for soo bandhigaa lafo. Sidaa darteed, xigtaa this ka mid ah cilmi-berrinkii paleontology waxaa loo yaqaan ma aha oo kaliya sida "Museum xayawaan qiroweyn".

Taariikh kooban

Trans xigtaa markii ugu horaysay la xusaa map ay British sahamisa James Ross ee 1841. Si kastaba ha ahaatee waxay horyaal ku fashilantay in ay gaaraan cagta ee ka danbow maxaliga ah. Kaliya ee 1908 duulaan Scott ah, Shackleton iyo Amundsen gudbay xigtaa inta lagu guda jiro safar dheer, loogu talagalay guusha ee South reer Poland.

Daraasad taxaddar Mountains Transantarctic ka dhacay 1947. Ujeedada this duulaan gaar ah waxaa soo abaabulay, kaas oo loo yaqaan "High boodi". dhul ayaa waxaa lagu bartay diyaaradaha. Sidaas darteed, cilmi ayaa awooday in ay ka dhigi maps Caddaynay ku filan gobolka.

Waa maxay meesha ugu sarreysa? buuraha Transantarctic gaaraan height ah 4528 m kor ku heerka badda cutubka cinwaankeedu yahay Kirk-Patrick. kayd dhagaxa of formation this waa mid isku urursan tirada ugu badan ee fossils kala duwan oo dhan. Tobanaan malaayiin sano waa si ay u ilaaliyaan ah xaaladaha cimilada aan fiicnayn ee nolosha iyo horumarka noolaha, waxa run ahaantii sharxayaa-fiirsashada sare ee haray ay idaad.

xaqiiqooyinka oo xiiso leh

Waxaa jira tiro ka mid ah dhibcood xiiso leh oo ku saabsan taariikhda waxbarasho Transantarctic Range ah:

1. In dhexe ee qarnigii la soo dhaafay ka baraf deegaanka go'day ka baraf ugu weyn ee abid la diiwaangeliyo cilmi. Its meesha waa 31 080 km, taas oo ka badan dhulka qaar ka mid ah dalalka Yurub.
2. Transantarctic Mountains, gaar ahaan, aaggooda magacaabay McMurdo, meelaha ugu oomane caalamka halkaas oo ma jiraan wax roobab muddo ka badan 2 milyan oo sano.
3. In wax-u Taylor Valley, taas oo ah qayb ka mid ah aragtida ah ee kala duwan oo buurta, waxaa jira biyo-dhac ah, halkaas oo durdurrada qulquliyey cado dhiig-cas. cilmi arrin noocan oo kale ah u sharax hawlaha biyo u damaysay ee alaabta bakteeriyada anaerobic.
4. Aasaasidda in uu yahay qayb ka mid ah meesha ugu sarreysa ugu sareeya ee xigtaa ee Kirk-Patrick, dhexe ee qarnigii la soo dhaafay, hadhaagii xayawaan qiroweyn a baalal leh oo la helay.

Waxa uu ahaa kuwaas oo sanadkii 1895, ka hor inta cilmi kale cag qaaradda ee Jacaylku. Dhismayaasha si cadaalad ah si fiican u sii raagayaan wakhtiga la joogo, sababtoo ah heerkulka aad u hooseeya kuwaas oo ka dhaca gobolka.

Gebogebadii

Trans-Antarctic Ridge weli mid ka mid ah meelaha ugu yaraan sahamiyey dunida ilaa maantadan la joogo. Eeda fog fog ee wax dabiiciga ah ee ilbaxnimada weyn, iyo sidoo kale xaaladaha cimilada adag. Isla mar ahaantaana xigtaa waa quruxda fantastik ah meesha, taas oo xusuusinayaa Bbc ka meerayaasha kale.
