Singayifumana i-commissions iqumrhu xa uthenga kumakhonkco kwindawo yethu. Nantsi indlela esebenza ngayo.
Isifundo esitsha sibonakalisile ukuba i-North Pole ixhonywe eSiberia kwikhaya layo lezebhulana kwi-canadan arctic njengendawo ezimbini ze-gestic ezifihlakeleyo phantsi komda wemfazwe.
La mabala, iindawo zemaguti engalunganga ephantsi kweCanada naseSiberia, zibandakanyeka kumlo ophumeleleyo-wonke umlo. Njengoko amaconsi atshintsha imilo kunye namandla e-magnetic ndle, kukho ophumeleleyo; Abaphandi bakufumanisa ukuba ngelixa amanzi aphantsi kweCanada esenza buthathaka ngo-1999 ukuya ku-2019, ukuba amanzi aphantsi kweSiberia akhule kwinyani ukuya eSiberia, "abaphandi babhala esifundweni.
"Asizange sibone nantoni na enje ngaphambili," Philrrenmore Covermore, umphandi okhokelayo kunye noProfeji oNcedisayo kwiDeophysics kwiYunivesithi yase-United Kingdom, uxelele isayensi ye-imeyile kwi-imeyile.
Xa izazinzulu ziqale zafumanisa i-North Pole (apho kukho amanqaku eNqanaba) ngo-1831, yayikwindawo yaseCanada yaseCanada yaseCanada. Abaphandi baqonde ukuba i-magnetic pole yemagnec ithambekele, kodwa ihlala kude kakhulu. Phakathi kwe-1990 ka-2005, ireyithi apho izibonda zemagneti zihamba-hamba kwimbali engaphezulu kweekhilomitha ezingaphaya kwe-9 (iikhilomitha ezili-15) ngonyaka, abaphandi babhala kwisifundo sabo.
Ngo-Okthobha ka-2017, i-Magnetic Pole iwele umgca womhla wamazwe jikelele kwi-hemisphere yasempuma, edlula kwiikhilomitha ezingama-390 (iikhilomitha ezingama-390) zendawo yendawo yasemantla. Ke i-magnetic poegnec pole iqala ukuhamba emazantsi. Kuninzi okuye kwatshintsha loo nto ngo-2019, oochwephesha banyanzelwa ukuba bakhulule unyaka wokuqala imodeli yehlabathi elitsha, imephu ebandakanya yonke into ukusuka kwi-Arlane I-GPS kwi-GPS ye-Smartplane.
Umntu unokuqikelela kuphela ukuba kutheni le nto i-arctic eshiyekileyo yaseCanada yeSiberia. Kwakude kude kude kufike i-Pelrmore kunye noogxa bakhe baqonda ukuba amaconsi ayeme ityala.
I-Magnetic Field iveliswa yi-allust yentsimbi ijikeleza kwi-ofisi ye-odolo yomhlaba. Ngenxa yoko, utshintsho kubunzima bentsimbi yokutshisa itshintsha indawo yemantla emantla.
Nangona kunjalo, imagnethi yemagneti ayiphelelanga kwi-core. Ngokutsho kwe-Livermore, imigca yasendle yemagneti "icwecwe" ehlabathini emhlabeni. Kuyavela ukuba la macomp avele apho avela khona. "Ukuba ucinga ngemigca ye-magnetic njenge spaghetti, amabala anjengesithuba seSpaghetti anamathela emhlabeni," utshilo.
Abaphandi bafumanise ukuba ukususela ngo-1999 ukuya ku-2019, i-Slick ephantsi kwe-canada ivela empuma ukuya entshonalanga phakathi kwendawo yokuhamba komhlaba, 'igalelo ".
Ukongeza, indawo enkulu yaseCanada yaya kufutshane neSiberia ngenxa yokwahlulahlula. Oku, yamomeleza ibala laseSiberia, abaphandi babhala.
Nangona kunjalo, ezi bhloko zimbini zikwimeko entle, ke "kuphela uhlengahlengiso oluncinci kulungelelwaniso lwangoku lungayibuyisela imeko yangoku ye-North Porle," abaphandi babhala esifundweni. Ngamanye amagama, i-tycula inqaku elinye okanye enye inokuthumela emantla eCanada.
Ngokwahlulwa ngokutsha kwentshukumo ye-magnetic ye-magnetic ye-thermati e-North ibonisa ukuba amaconsi amabini, kwaye ngamanye amaxesha amathathu, aphembelele isikhundla sePole yaseNyakatho ngokuhamba kwexesha. Kule minyaka ingama-400 idlulileyo, amaconsi ayebangele i-North Pole ukuya kwiLinger Canada, bathi abaphandi bathi.
"Kodwa kwiminyaka engama-7000 edlulileyo, [i-North Pole] ibonakala ngathi ihamba ijikeleze i-polegraphic pole ngokuvakalayo ngaphandle kokubonisa indawo ekhethiweyo," Abaphandi babhala ezi zifundo. Ngokwemodeli, nge-1300 BC I-Pole iguqukile eSiberia.
Kunzima ukuyithetha into eza kwenzeka. "Ukuxela kwethu kukuba izibonda ziya kuqhubeka nokuya eSiberia, kodwa kunzima kakhulu ukuba ikamva linzima kwaye asinakuqiniseka," yatsho i-Livermore.
Uqikelelo luya kusekelwa kwi "Igekhi ebonakalayo yentsimi ye-gegragnetic emhlabeni nakwisithuba kwiminyaka embalwa elandelayo," abaphandi babhala kwisifundo esidlulileyo, "abaphandi babhala kwisifundo esidlulileyo," abaphandi babhala kwisifundo esipapashiweyo ngo-5 kwijenali yendalo.
