Mlilo Antarctica - iimfihlelo eyay

Antarctica - kwilizwekazi twi yoonombombiya kunye intlango polar komkhenkce obungunaphakade, wokugqibela yokuvulwa yezwe namhlanje eyaziwa kakubi nokufihla iimfihlelo avezwe. Mlilo Antarctica - omnye wabo eemfihlelo ukuba akukho mntu ungathembekanga ungxamile ukuvula.

Ezifihlakeleyo ice ubukhulu

Active and extinct, umhlaba kwamanzi - Namhlanje kwilizwekazi mlilo ka-Antarctica linekhathalogu 35 phezu komhlaba, yaye ubuncinane 18 kubo - sokubambela. Owokugqibela wafunyanwa ngo-2008, ifihlakele phantsi kwe ice kwaye ibekwe kufutshane Gulf of Pine Island kwi Hudson kwiiNtaba. Ngathi yabhaqwa zokuhlola ngumkhenkce ukusuka emoyeni, nokuba bangaphi kubo abangakhange bunako?

Eyokuqala, kodwa hayi wokugqibela

Lo mbuzo, "Ngaba kukho mlilo Antarctica?" Waphelelwa ukufaneleka kude 1841, xa hambo kaYakobi Ross wabona mlilo ezimbini - Erebus aleleyo obambeleyo Terror (igama ngokuba iinqanawa hambo). Ukususela ngoko waqalisa isifundo mlilo kunye izinto ezintsha. Ngoko ke, ngo-2010, kuye kwakho iingxelo kuvulwe nomxokelelwane mlilo zangaphantsi 12 ka-Antarctica apho. Ukusebenzisa sonar kuye kwafunyanwa ukuba kukho ukuphakama efikelela oziikhilomitha ezi-3. Bosixhenxe bakhuthele, yaye amanzi extinct mlilo ndawo ububanzi of yeekhilomitha ukuya ku-5.

Erebus mlilo

Eyona ongezantsi zonke mlilo ehlabathini - Erebus - lunobude phantse 4000 iimitha ngaphezu komphakamo wolwandle wentaba ubukhulu 805 eemitha ezinzulu ngeemitha 274. Le yenye mlilo ezintathu umhlaba, leyo ezinzulwini echibini mlilo ungaphelelwayo mlilo. Loo nto inika Erebus ukukhanya bokuhlala ukuba ube sisibane bonke oomatiloshe loLwandle Ross. Le yokugqibela yeminyaka 8 ezilikhulu mlilo enkulu ngowe-1972, xa mlilo betekisi ukuya kubude besakhiwo esinemigangatho ezisibhozo.

Conquest of Erebus - ngodumo

Kuba abaphandi e Antarctica enjengokugwencela kulo mlilo esiyingozi iye phantse phithi. Okokuqala wayoyisa ngo-1908, iqela iingcali ze hambo ka Ernest Shackleton, owayeneminyaka eli-50 ubudala. Kuyinto le abaphandi kuqala wabona chibi mlilo kule ndawo.

Izazi ukusuka eNew Zealand ngowe-1974, wamisa inkampu komgodi, kodwa umsebenzi lo mlilo akazange avumele ukuba ukuhlola umngxuma embilwini. Nangona indlela eya mlilo ukuba uvimba iincopho ezininzi enomkhenkce ngonyaka zithontelane kuyo, abaphandi, kakhulu.

mlilo Inkohliso

phakathi Shetlanskih wesiqithi, 850 km-kumzantsi mpuma Cape Horn nguye umsunguli ukwenzeka Bay Port Foster. Oku lo mlilo esebenzayo ingqalelo uxanduva dubulo owaziwayo. Mlilo kuvulwa ngo-1820, uCaptain Uilyam Smit, kwaye ngo-1960 kwabonakala UK Station elidityanelweyo, Chile kunye Argentina. Kwixesha 1967-1969 kaThixo, ngenxa mlilo ezininzi, Chile kunye UK izikhululo ziye kutshatyalaliswa. Kuphela abano, nto leyo 2000 ujoyine baseSpeyin.

Inkohliso eliyimfihlakalo

Le enqabileyo "mlilo ice", umhlaba ophantsi glacier Ebubanzini iimitha ukuya ku-100. Love ihamba ngokucotha yaye uza kumphezulu imali enkulu ngenxa yokungcola. Mlilo namhlanje ukuba ngokupheleleyo ngemvelaphi mlilo - nokuba lo mlilo kudaleka (divergence uqweqwe), nokuba ukhandwa subduction (enye emanzini uqweqwe ngaphantsi kwenye) ziitectonic plates.

Mount Sidley

Land Meri Berd beesekethe iquka intaba mlilo Ridge kwiBhodi (Range Executive Committee). Ukuphakama yeNtaba Sidley malunga 4.3 amawaka neemitha, unyawo - 2,5 amawaka eemitha. Enye cala lentaba enza mlilo mngxuma mlilo enobubanzi kweekhilomitha ezi-5. Ububanzi umkhenkce ukutyabeka ufikelela iikhilomitha 2 ukuba umkhenkce linyibilike, ivela apha ngohlobo Japan Ncebakazi yesibini mlilo.

Mlilo Antarctica kunye nekamva le planethi

Ngokutsho Nature Geoscience, umsebenzi mlilo ichaphazela isantya ice yokunyibilikisa. obushushu evela Antarctica mlilo, wacanda kolu qweqwe lomhlaba, ebangela kozinzo yezwe ice iqokobhe. Izazinzulu ziye eyenziwe imaphu umhlaba ukususela kwalowo ibiqikelelwe ye ice Antarctic. Yaye ayinayo kakhulu Intshona Melika kunye kwimimandla yonxweme India. Ngokupheleleyo emanzini London kunye yaseVenice, eNetherlands Denmark. Phakathi amazwe eziya kukuva ubunzima, akukho Russian.

maphupho Antarctic

Ngowe-2017, loo matshini ingxelo ngemisebenzi NASA kule ndawo ye-mlilo Mount iErebus zokusetsha portal kwabanye ilizwe ezafa yabasemzini. Ngoku wonke umntu uyazi ukuba lo mlilo ibekwe e Antarctica.

A elikhulu Ileta imitha-mbini "M" kwesinye liye kungaziwa elide. Kodwa kwenzeka ngale ndlela ngumphandi Polish immortalized igama nenekazi kwentliziyo yakhe uMagda. Noko ke, izinto ekhethiweyo umdla - lelona ilindle penguins.

iincopho ezimbini iliwa ekungeneni Lemaire Channel ogama kakhulu olwahluke - "Boob Una." Njengenxalenye kwiphulo British ngokwenene ndiyintombazana Una. Okubangel 'umdla kukuba, ekubeni ezinye mlilo ngoku ongenagama.

E Antarctica, a lot of amachibi subglacial ngamanzi ahlaziyekileyo. Ngokutsho ezinye iingqikelelo, kukho malunga 140 Kodwa inkulu - East. ububanzi bayo angu-50 kwaye ubude - 250.

Kodwa i-Taylor Glacier kwemali Blood Falls. Le meko kungenxa umsebenzi kwegciwane echibini subglacial. Baya cell intsimbi bivalent, leyo amabala amanzi umoya ngombala limfiliba.

Ukuze ukuphoxeka sabaninzi, akukho amabhere e Antarctica. Ezidla apha kuphela ulwandle - obulale kookrebe kodwa ngumkhenkce. Kungenxa yoko le nto oonombombiya kumhlaba onjalo ngqindilili.

E Antarctica, kukho 5 izikhululo polar Russian. Eyona inkulu - "East" - na kummandla geodesic South Pole.
