<prompt> Fingqa isihloko: Kuye kwatholakala ungqimba olusha olunamathelayo kakhulu engxenyeni engezansi yomhlabathi. Lokhu okutholwe kungase kuchaze ukuthi kungani izingxenye zamapuleti omhlaba acwilayo ngezinye izikhathi ziqine futhi ziqine ngaphansi komhlaba. Kungachaza nokuthi kungani ukuzamazama komhlaba kwenzeka ekujuleni komhlaba, okusikisela ukuthi kushisa kakhulu kunalokho obekucatshangwa ngaphambili. Lapha kuboniswe isithombe esenziwe lula se-slab esuka kwelinye lamapuleti omhlaba acwila engxenyeni engenhla ye-mantle engenhla, bese igxuma futhi ihlanganiswe ekujuleni kwamamayela angu-930, lapho ukuhlolwa kwe-University of Utah kusikisela khona ukuba khona kwesendlalelo esiqinile noma esiqinile eMhlabeni. Lolu cwaningo lwenziwa ososayensi e-University of Utah ngokuchoboza amaminerali phakathi kwamadayimane ukuze balingise izimo ezingaphakathi eMhlabeni. Izingqimba eziyinhloko zomhlaba ziyingqimba encane engamakhilomitha ayisithupha kuya kwangu-80 ukujula, ingubo engaba amakhilomitha angu-2 900 ukujula nenhliziyo yensimbi. Kodwa kunezigaba ezingaphansi. Ingqimba yomhlaba nezinye izingxenye ze-mantle engenhla zakha amapuleti e-tectonic noma e-lithospheric angamamayela angu-60 kuya kwangu-90 97 kuya ku-145km ubude afana nohlangothi oluphezulu lwamabhande athutha amazwekazi nezingqimba zasolwandle. Ziyimbangela yokwakheka kwamazwekazi, futhi zisasebenza - njengoba ukuzamazama komhlaba nokuqhuma kwentaba-mlilo kubonisa. Nokho, abacwaningi abakaze bakwazi ukuthola ukuthi kungani uMhlaba waba namapuleti ama-tectonic, kuyilapho amanye amaplanethi engazange abe nawo. Ngonyaka odlule, iYale yathi yayisixazulule le mfihlakalo - futhi yathi isihluthulelo siyimaminerali amancane asemadwaleni. Lolu cwaningo lusikisela indlela uMhlaba owaba ngayo nesikhathi owaba ngaso nesinye sezici zawo ezivelele - amapuleti aqinile ezwekazi - nokuthi kungani uVenus, umakhelwane woMhlaba ofana nomzukulu, engazange abe naso. Sicabanga ukuthi konke kuncike ekuziphatheni kwezinhlayiya ezincane zamaminerali ngaphakathi kwamadwala, kusho isazi sesayensi yokwakheka komhlaba saseYale uDkt. David Bercovici, umbhali oyinhloko wocwaningo olwanyatheliswa kumagazini i-Nature. Abacwaningi bathi ezinsukwini zokuqala zoMhlaba, ukuhlangana kwe-mantle kwabangela izindawo ezibuthakathaka ku-lithosphere - igobolondo elingaphandle kakhulu lomhlaba. Lezi zindawo zaqhubeka, zaba imingcele yamapuleti, futhi ekugcineni...  <response>: Ucwaningo lwenziwa ososayensi e-University of Utah. Aqhekeza amaminerali phakathi kwamadayimane ukuze alingise umnyombo woMhlaba. Futhi bathola ukuthi kumelwe ukuba kunesifunda esisha esingamakhilomitha angu-930 ngaphansi komhlaba. Indawo ye-supercous ingase ichaze ukuthi kungani amanye amapuleti engashoni. Futhi okutholakele kubonisa nokuthi ingaphakathi leMhlaba lishisa kakhulu kunalokho obekulindelekile.
