Kera cyane, imigabane yose yari yibanze mugihugu kimwe cyitwa Pangea.Pangea yatandukanijwe hashize imyaka miriyoni 200, kandi ibice byayo byanyuze hejuru yamasahani ya tectonic, ariko ntabwo arigihe cyose.Umugabane uzongera guhura mugihe kiri imbere.Ubushakashatsi bushya buzatangwa ku ya 8 Ukuboza mu nama yo ku rubuga rwa interineti mu nama y’Abanyamerika y’ubumwe bwa geofiziki, yerekana ko ahazaza h’umugabane wa Afurika hashobora kugira ingaruka zikomeye ku isi ndetse n’imiterere y’ikirere.Ubu buvumbuzi nabwo ni ingenzi mu gushakisha ubuzima ku yindi mibumbe.
Ubushakashatsi bwatanzwe kugirango butangwe nubwa mbere mu kwerekana ikirere cy’umugabane wa kure.
Abahanga ntibazi neza uko umugabane utaha uzaba umeze cyangwa aho uzaba.Ikintu kimwe gishoboka nuko mumyaka miriyoni 200, imigabane yose usibye Antaragitika ishobora gufatanya hafi ya Pole y'Amajyaruguru gushinga Arumeniya ndengakamere.Ikindi gishoboka nuko "Aurica" ​​yashoboraga gushingwa kuva kumugabane wose wahuzaga na ekwateri mugihe cyimyaka igera kuri miliyoni 250.
Uburyo ubutaka bwikirenga Aurika (hejuru) na Amasia butangwa.Ibihe bizaza byerekanwe kumyenda, kugirango ugereranye nu mugabane wa none.Inguzanyo y'ishusho: Inzira n'ibindi.2020
Mu bushakashatsi bushya, abashakashatsi bifashishije icyitegererezo cy’ikirere cya 3D ku isi kugira ngo bagaragaze uburyo ibishushanyo mbonera by’ubutaka byagira ingaruka ku miterere y’ikirere ku isi.Ubushakashatsi bwayobowe na Michael Way, umuhanga mu bya fiziki mu kigo cya NASA cya Goddard Institute for Space Studies, igice cy’ikigo cy’isi cya kaminuza ya Columbia.
Itsinda ryasanze Amasya na Aurika bigira ingaruka ku kirere mu guhindura ikirere n’inyanja.Niba imigabane yose yarahurijwe hamwe ikikije ekwateri mugihe cya Aurica, Isi yarangiza igashyuha kuri 3 ° C.
Mu bihe bya Amasya, kubura ubutaka hagati yinkingi byahungabanya umukandara wa convoyeur wo mu nyanja, kuri ubu utwara ubushyuhe buva kuri ekwateri ukagera ku nkingi kubera kwegeranya ubutaka bukikije inkingi.Nkigisubizo, inkingi zizaba zikonje kandi zitwikiriwe nubura umwaka wose.Urubura rwose rugaragaza ubushyuhe busubira mu kirere.
Hamwe na Amasya, “urubura rwinshi rugwa,” Way yabisobanuye.Ati: "Ufite amabati kandi ubona ibitekerezo bya ice albedo bikunda gukonjesha isi."
Usibye ubushyuhe bukonje, Way yavuze ko inyanja ishobora kuba nkeya mu bihe bya Amasya, amazi menshi yagwa mu rubura, kandi ibihe by'urubura bishobora gusobanura ko nta butaka bunini bwo guhinga.
Avuga ko Ourika we ashobora kuba yerekeza ku nyanja.Isi yegereye ekwateri yakuramo urumuri rwizuba rukomeye aho, kandi ntihazabaho ibibarafu bya polar byerekana ubushyuhe buturuka ku kirere cy’isi, bityo ubushyuhe bw’isi bukaba buri hejuru.
Mu gihe Way igereranya inkombe za Aurica n’inyanja ya paradizo yo muri Berezile, “irashobora gukama imbere mu gihugu.”Niba igice kinini cyubutaka bubereye ubuhinzi bizaterwa no gukwirakwiza ibiyaga nubwoko bwimvura bakira - ibisobanuro bitavuzwe muri iyi ngingo, ariko bishobora gushakishwa mugihe kizaza.
Ikwirakwizwa rya shelegi na barafu mu itumba no mu cyi muri Aurika (ibumoso) na Amasya.Inguzanyo y'ishusho: Inzira n'ibindi.2020
Icyitegererezo cyerekana ko hafi 60 ku ijana by'akarere ka Amazone ari byiza ku mazi meza, ugereranije na 99.8 ku ijana by'akarere ka Orica - ivumburwa rishobora gufasha mu gushakisha ubuzima ku yindi mibumbe.Kimwe mu bintu by'ingenzi abahanga mu bumenyi bw'ikirere bareba iyo bashakisha isi ishobora guturwa ni ukumenya niba amazi y’amazi ashobora kubaho ku isi.Iyo ugereranije iyindi si, bakunda kwigana imibumbe itwikiriwe ninyanja cyangwa ifite topografiya isa nisi ya none.Nyamara, ubushakashatsi bushya bwerekana ko ari ngombwa gusuzuma aho ubutaka bugenzurwa niba ubushyuhe bugabanuka muri zone "ituwe" hagati yubukonje no guteka.
Nubwo bishobora gufata abahanga mu myaka icumi cyangwa irenga kugirango bamenye ikwirakwizwa ry’ubutaka n’inyanja ku mubumbe w’izindi nyenyeri, abashakashatsi bizeye ko bazagira isomero rinini ry’ubutaka n’inyanja kugira ngo bigaragaze imiterere y’ikirere bishobora gufasha kugereranya aho umuntu ashobora gutura.imibumbe.isi ituranye.
