Turashobora kubona komisiyo ishinzwe mugihe ugura mumahuza kurubuga rwacu. Dore uko ikora.
Ubushakashatsi bushya bwerekanye ko inkingi y'Amajyaruguru yegamiye muri Siberiya kuva mu rugo rwayo gakondo mu majyaruguru ya Kanada nka cluster nini yihishe mu nzego z'ibanze mu ntambara ikomeye mu ntambara.
Ibi bibanza, ahantu habi muri magneti mbi munsi ya Kanada na Siberiya, bagize uruhare mu kurwana-byose. Mugihe ibitonyanga bihindura imiterere n'imbaraga z'umurima wa magneti, hari uwatsinze; Abashakashatsi basanze mu gihe ubusazi bw'amazi munsi ya Kanada bwagabanutse guhera mu 1999 kugeza muri 2019, imisatsi y'amazi munsi ya 2019 kugeza 2019. "Twese hamwe, izi mpinduka zatumye muri Siberiya yerekeje muri Siberiya."
Phil Livermore, ntitwigeze mbona umushakashatsi nk'uwo, umwarimu wungirije wa geofiya muri kaminuza ya Leeds mu Bwongereza, yabwiye siyanse ya Live.
Iyo abahanga bavumbuye bwa mbere Pole y'Amajyaruguru (aho abahanga mu by'imikono) mu 1831, byari mu karere ka Nunaadian yo mu majyaruguru ya Nanaadian. Abashakashatsi bahise bamenya ko inkingi ya magnetic y'Amajyaruguru yakunze kugenda, ariko mubisanzwe ntabwo ari kure cyane. Hagati ya 1990 na 2005, igipimo inkingi za magneti zerekezaga kuva mu mateka yo mu mateka itarenze ku bilometero 15 ku mwaka, abashakashatsi bandika mu bushakashatsi bwabo.
Ukwakira 2017, Pole ya magnetiki yambutse umurongo mpuzamahanga w'itariki mpuzamahanga mu burasirazuba bw'iburasirazuba, arenga mu bilometero 242 (ibirometero 390) bya geografiya. Hanyuma urubuga rwa magnetic rurneti rutangiye kwimuka mumajyepfo. Byinshi byahindutse kuburyo muri 2019, abagenzi bahatiwe kurekura umwaka moderi nshya ya magneti yisi, ikarita ikubiyemo ibintu byose kuva ku ndege ya GPS ya Smartphone to GPS.
Umuntu arashobora gukeka gusa impamvu arctique yavuye muri Kanada ya Siberiya. Iyo yari Lovermore na bagenzi be bamenye ko ibitonyanga byaryozwa.
Umurima wa magneti wakozwe nicyuma kizunguruka ku isi yimbitse. Rero, impinduka muri misa ya swingi ihindura umwanya wamajyaruguru ya magneti.
Ariko, umurima wa magneti ntabwo ugarukira gusa. Nk'uko Livermore, umurongo wa magneti "" imigezi "mu isi. Biragaragara ko izi zito zigaragara aho iyi mirongo igaragara. Ati: "Niba utekereza ku murongo wa magnetique nka spaghetti yoroshye, ahantu hameze nk'urutare rwa Spaghetti ruva mu isi".
Abashakashatsi basanze kuva mu 1999 kugeza muri 2019, hatanzwe munsi ya Kanada mu burasirazuba, ariko muri rusange, urugero rwabaye mu miterere y'isi. "
Byongeye kandi, ahantu hakomeye Abanyakanadiya begereye umwe wa Siberiya kubera gutandukana. Ibi na byo, byashimangiraga umwanya wa Siberiya, abashakashatsi bandika.
Abashakashatsi bandika mu bushakashatsi bavuga ko ibyo bikoresho byombi biri mu buringanire bworoshye, bityo "Ihinduka ryonyine ku iboneza ririho rirashobora guhindura inzira y'ubu. Muyandi magambo, gusunika kugeza ingingo imwe cyangwa ubundi birashobora kohereza amajyaruguru ya magneti gusubira muri Kanada.
Iyubakwa rya Pole ya kera ya magnetic kuri Pole y'Amajyaruguru yerekana ko ibitonyanga bibiri, kandi rimwe na rimwe bitatu, byagize ingaruka kumwanya wa Pole y'Amajyaruguru mugihe. Mu myaka 400 ishize, ibitonyanga byatumye Pole y'Amajyaruguru zitinda mu majyaruguru ya Kanada, abashakashatsi bavuga.
Abashakashatsi banditse bati: "Ariko mu myaka 7,000 ishize, [Pole y'Amajyaruguru] igaragara ko yazengurutse inkingi ya geografiya atayerekanye aho ahitamo." Ukurikije icyitegererezo, kuri 1300 BC Pole nayo yimukiye muri Siberiya.
Biragoye kuvuga ibizaba bikurikira. Livermore yagize ati: "Guhangana kwacu nuko inkingi zizakomeza kwimuka muri Siberiya, ariko hagamijwe guhanura ejo hazaza haragoye kandi ntidushobora kumenya neza."
Abashakashatsi banditse mu bushakashatsi bwasohoye kumurongo, bakurikiranye ibisobanuro birambuye ku murima Gemagnetic ku isi ndetse no mu gihe mu myaka mike yakurikiyeho.
Mugihe gito, urashobora kwiyandikisha kuri kimwe mu binyamakuru byacu bya siyansi byagurishijwe cyane nka $ 2.38 buri kwezi cyangwa 45% ku giciro gisanzwe mumezi atatu yambere.
