Esikhathini eside esidlule, wonke amazwekazi ayegxile ezweni elilodwa elibizwa ngokuthi iPangea.IPangea yahlukana phakathi eminyakeni eyizigidi ezingu-200 edlule, futhi izingcezu zayo zazulazula kuma-tectonic plate, kodwa hhayi unomphela.Amazwekazi azophinde ahlangane futhi esikhathini esizayo esikude.Ucwaningo olusha, oluzokwethulwa ngoDis. 8 ngesikhathi sephosta ku-inthanethi emhlanganweni we-American Geophysical Union, luphakamisa ukuthi indawo yesikhathi esizayo yezwekazi elikhulu ingase ibe nomthelela omkhulu ekuhlaleni koMhlaba nokuzinza kwesimo sezulu.Lokhu okutholakele kubalulekile futhi ekusesheni ukuphila kwamanye amaplanethi.
Ucwaningo oluthunyelwe ukuze lushicilelwe lungolokuqala ukwenza imodeli yesimo sezulu sezwekazi elikude lesikhathi esizayo.
Ososayensi abaqiniseki ukuthi i-supercontinent elandelayo izobukeka kanjani noma ukuthi izotholakala kuphi.Okunye okungenzeka ukuthi eminyakeni eyizigidi ezingu-200, wonke amazwekazi ngaphandle kwe-Antarctica angajoyina eduze neNorth Pole ukuze akhe izwekazi elikhulu i-Armenia.Okunye okungenzeka ukuthi “i-Aurica” ​​yayingavela kuwo wonke amazwekazi ahlangana enkabazwe esikhathini esiyiminyaka eyizigidi ezingu-250.
Indlela amazwe ase-Aurika (ngenhla) kanye ne-Amasia asakazwa ngayo.Ukuma komhlaba kwesikhathi esizayo kukhonjiswe ngokumpunga, uma kuqhathaniswa nezinhlaka zamanje zezwekazi.Ikhredithi yesithombe: Way et al.2020
Ocwaningweni olusha, abacwaningi basebenzise imodeli yesimo sezulu se-3D ukuze benze imodeli yokuthi lokhu kulungiselelwa okubili komhlaba kuzothinta kanjani uhlelo lwesimo sezulu somhlaba.Ucwaningo beluholwa nguMichael Way, isazi sefiziksi e-NASA i-Goddard Institute for Space Studies, eyingxenye ye-Earth Institute yase-Columbia University.
Ithimba lithole ukuthi i-Amasya ne-Aurika zithonya isimo sezulu ngendlela ehlukile ngokushintsha ukujikeleza komkhathi nolwandle.Ukube wonke amazwekazi abehlangene azungeze inkabazwe esimweni se-Aurica, uMhlaba ungagcina usufudumala ngo-3°C.
Esimweni se-Amasya, ukuntuleka komhlaba phakathi kwezigxobo kuzophazamisa ibhande lokuthutha lolwandle, okwamanje elihambisa ukushisa ukusuka enkabazwe kuya ezigxotsheni ngenxa yokuqoqwa komhlaba ozungeze izigxobo.Ngenxa yalokho, izigxobo zizobanda futhi zimbozwe yiqhwa unyaka wonke.Lonke leli qhwa libonisa ukushisa emuva emkhathini.
Ngo-Amasya, “iqhwa eliningi liyawa,” kuchaza uWay."Unamashidi eqhwa futhi uthola impendulo esebenzayo ye-ice albedo evame ukupholisa iplanethi."
Ngaphezu kwamazinga okushisa apholile, u-Way uthe amazinga olwandle angaba ngaphansi esimweni sase-Amasya, amanzi amaningi azovaleleka eqhweni, futhi izimo ezineqhwa zingasho ukuthi awukho umhlaba omningi wokulima izitshalo.
Ngakolunye uhlangothi, kungenzeka ukuthi u-Ourika ugxile kakhulu ebhishi, usho kanje.Umhlaba oseduze nenkabazwe ubungamunca ukukhanya kwelanga okunamandla lapho, futhi bekungeke kube khona izingqimba zeqhwa ezibonisa ukushisa okuvela emkhathini womhlaba, ngakho amazinga okushisa embulunga yonke abeyoba phezulu.
Nakuba uWay eqhathanisa ugu lwase-Aurica namabhishi ayipharadesi aseBrazil, “kungase kome kakhulu phakathi nezwe,” uyaxwayisa.Ukuthi ingxenye enkulu yomhlaba ifaneleka kwezolimo kuyoxhomeka ekwabiweni kwamachibi nasezinhlotsheni zemvula ayitholayo—imininingwane engavezwanga kulesi sihloko, kodwa okungase kuhlolwe ngayo esikhathini esizayo.
Ukusatshalaliswa kweqhwa neqhwa ebusika nasehlobo e-Aurika (kwesokunxele) nase-Amasya.Ikhredithi yesithombe: Way et al.2020
Ukumodela kukhombisa ukuthi cishe amaphesenti angama-60 endawo yase-Amazon ilungele amanzi awuketshezi, uma kuqhathaniswa namaphesenti angama-99.8 endawo yase-Orica - okutholakele okungasiza ekufuneni ukuphila kwamanye amaplanethi.Esinye sezici eziyinhloko izazi zezinkanyezi ezizibhekayo lapho zisesha imihlaba okungahlalwa kuyo ukuthi amanzi awuketshezi angakwazi yini ukuphila phezu komhlaba.Lapho bemodela le eminye imihlaba, bavame ukulingisa amaplanethi ambozwe ngokuphelele ulwandle noma abe nesimo sezulu esifana nesoMhlaba wanamuhla.Kodwa-ke, ucwaningo olusha lubonisa ukuthi kubalulekile ukucabangela indawo yezwe lapho uhlola ukuthi amazinga okushisa awela yini endaweni “okuhlalwa kuyo” phakathi kokuqhwa nokubilisa.
Nakuba kungase kuthathe ososayensi iminyaka eyishumi noma ngaphezulu ukunquma ukusatshalaliswa kwangempela komhlaba nezilwandle kumaplanethi kwezinye izinhlelo zezinkanyezi, abacwaningi banethemba lokuba nomtapo wezincwadi omkhulu wedatha yomhlaba nolwandle wokumodela isimo sezulu esingasiza ukulinganisa okungaba khona ukuhlala.amaplanethi.imihlaba engomakhelwane.
U-Hannah Davies no-Joao Duarte baseNyuvesi yase-Lisbon kanye no-Mattias Greene wase-Bangor University e-Wales bangababhali ababambisene balolu cwaningo.
Sawubona Sarah.Igolide futhi.O, isimo sezulu sizobukeka kanjani lapho umhlaba ushintsha futhi futhi izilwandle ezindala zivaliwe futhi zivuleka ezintsha.Lokhu kufanele kushintshe ngoba ngikholelwa ukuthi imimoya nemisinga yolwandle kuzoshintsha, kanye nezakhiwo ze-geological zizohambisana kabusha.I-North American Plate ihamba ngokushesha eningizimu-ntshonalanga.Ipuleti lokuqala lase-Afrika lahlasela iYurophu, ngakho kwaba nokuzamazama komhlaba okuningana eTurkey, eGrisi nase-Italy.Kuyoba okuthakazelisayo ukubona ukuthi iBritish Isles iya ngaphi (i-Ireland isuka eNingizimu Pacific esifundeni solwandle. Yebo indawo yokuzamazama komhlaba ye-90E isebenza kakhulu futhi i-Indo-Australian Plate ibheke e-India ngempela.
