Kutheni ukufunda Antarctica osisityebi kweli lizwekazi?

Antarctica - ilizwe ice obungunaphakade penguins. Ngoko ke, ubuncinane, loo okwangoku imela ubuninzi abemi behlabathi. Kodwa ukuba ubomi kukho phantse akunakwenzeka (oku, apho abahlali owoyamaniswe kwimimandla ezifudumeleyo zehlabathi) ngenxa kumaqondo obushushu asezantsi, kutheni Antarctica? Yintoni unomdla kakhulu kulo maleko elikhulu komkhenkce South Pole?

Imbali ukufunyanwa kunye nesifundo Antarctica

January 28, 1820 yayisisihlandlo sokuqala wabona kwilizwekazi wesithandathu. Kokuba ifike hambo Russian, ezibandakanya iinqanawa ezimbini elikhokelwa Faddeem Faddeevichem Bellinsgauzenom kunye uMikhail Petrovich various. Ngaphambi nje uzama ukufumana kuye, iziqithi ezininzi esafunyanwa ngaxeshanye ngayo. Lo mhla azinako kubizwa kwinqanaba lokuqala xesha, xa uphando olubanzi Antarctica.

Isiganeko esilandelayo ebalulekileyo yezwe abandayo obungunaphakade wayeza ukufikelela kwiziko layo, yaye eneneni - ngokoMthetho South Pole (ukuba malunga enye). Elinye iqela, ekhokelwa yi-Norwegian Amundsen Raul, kwaye okwesibini, kunye nentloko Robert Scott (eNgilani), ngoDisemba 1911 noJanuwari 1912, ngokulandelelana, wegqitha indlela nzima, yaye siqokelele ulwazi oluninzi ebalulekileyo malunga ngaphakathi kweli lizwekazi. Esi siganeko olukhulu lwaba yintlekele: Scott umkhankaso batshabalala kwiimeko ezimaxongo nje kwiikhilomitha ezimbalwa ukusuka kwisiseko, apho bakwazi ufudumale kwaye uhlaziye stock ukutya.

Kamva, ngoNovemba 1912 kwafunyanwa, ukuhlangulwa uhambo lokuqala lentente kunye kwakungcwatywa amalungu eqela ephosiweyo lokuqala isisu ezintathu.

mpumalanga Research: injongo

Ukuze ukufunda Antarctica leyo kucaca ukuba ulingene iinkcukacha ngakumbi kweli lizwekazi ethile. Okokuqala - lo isitokhwe amanzi acocekileyo. Kwi-avareji, lo maleko omkhenkce ubukhulu oziimitha 2000 kwaye ummandla million 14 square metres, ezenza malunga nesi-90% ndingowenzala ngamanzi amatsha kulo mhlaba.

Ukuze ufumane inkcazelo engakumbi malunga ice

Okubangel 'umdla kukuba, nokuba kwiimeko ezinzima zasebusika, kukho amachibi gumbi kunye nemilambo. Indawo yezwe kukuba kwiqondo lobushushu ngaphantsi zero imitha yelanga ikwazi zokwaphula ngumkhenkce. Kukho "kumgxobhozo", kwakheka njenge lasehlotyeni amanzi nekhephu. aba bahamba kunye ice kunye sicatshulwa nzima kuphando zothutho ukuya kangangokuba ngaphandle uncedo akuthethi ukuphuma. Ehlotyeni, nayo yimisinga ezivulekileyo kunye namachibi, kunye nokuqalisa kobusika, ukuba imperceptible phezu kwamanzi, njengoko ezihlawulelwayo ngomaleko omkhulu yomkhenkce nekhephu, imimoya enamandla nametennogo. Ngoko ke, amachibi ezimbini likhulu Antarctica zezi kubunzulu yeemitha 3000. Ngoku becinga ukuba bakwazi kufumaneka njani? Umsebenzi oosonzululwazi wawuthandeka enkulu.

Hi ndlela leyi, malunga imimoya. avareji ngesantya sabo yonyaka - 12 km / h, kodwa phantsi kweemeko ezithile, ityala ukuba isantya 50-60 km / h, yaye ngamanye amaxesha onke 90.

Kutheni ukufunda Antarctica? Ewe, ngokuba ihlabathi eyahlukileyo ngokupheleleyo. Yena kuyabanda kwaye mhle, kakhulu yaye iyabulala, yena ezele ingozi kunye mfihlelo. Lo wokuqala.

Izibonelelo kunye neempawu indawo

Ke kaloku, malunga iingenelo. Xa isifundo kwelizwekazi kwafunyanwa iidipozithi ezininzi bezimbiwa. Xa abantu udle konke zityebi kwamanye amazwekazi, uya kuza nayo yonke Antarctica. Ukuza kuthi ga ngoku, oku akwenzeki ngokunxibelelene Madrid Protocol yangoku (1991), othintela umsebenzi ezoshishino kunye nokuveliswa nayiphi efosili, ngokuba kwilizwekazi kubalulekile ukuba wonke umhlaba kwindawo yokuqala, njengenxalenye yenkqubo imozulu lwemfundo.

Esi sesinye isizathu sokuba ukufunda le Antarctica, ukubeka iliso kumgangatho ukunyibilika komkhenkce ngokuphindaphindiweyo waphakamisa imibuzo malunga ifuthe warming jikelele kwi "efrijini" engundoqo uMhlaba. Ngokuqinisekileyo konke ndeva ngale ngxaki.

Nezokugqibela, ukufunda Antarctica oko kubizwa ngokuba ligama eliqhelekileyo - inzululwazi. Apha kukho isifundo iimpembelelo ilanga ebudeni ezahlukeneyo yobukho koMhlaba, tracking umsebenzi obuphethelene, nokuvavanya nobuchwepheshe ukulungiselela isifundo kweNyanga Mars.
