Sesiyazi ukuthi izintaba-mlilo ezitholakala emhlabeni wethu zingumphumela we umagma ukhuphuka ngengubo, kodwa besilokhu sikwazi ukubuza ukuthi zingaqhamukaphi.
Ngokokuqala ngqá a Imephu eningiliziwe ye-3D yengaphakathi lomhlaba lapho ngifunda iphethini yamagagasi okuzamazama komhlaba. Imodeli ikhombisa ingubo, ngqo ukusuka lapho kugeleza khona idwala eliphilayo nokuthi liqala phakathi kwengqimba engaphandle nengubo engezansi noma okungaba ukuphela kukaGutenberg ukukhuphukela phezulu, lapho kuhlangana khona nezindawo zentaba-mlilo kuqweqwe lomhlaba.
Amakholomu entaba-mlilo awaholeli endleleni eya phezulu ngendlela eqondile, kepha kunalokho ubujamo obuyinqaba ngokusonteka okungalindelekile. Manje sekuyaziwa futhi ukuthi izintaba-mlilo eziningi emhlabeni, ezinjengeziqhingi zaseziqhingini zasePacific, zivela "kuma-blobs" amabili amakhulu edwala elishisayo endaweni eshiwo ngenhla njenge-Gutenberg discontinuity.
Imodeli ayiphelele ngokwayo, njengoba kungenjalo bopha izimpaphe ezithile kwezinye izintaba-mlilo, njengaleyo etholakala eYellowstone National Park. Kunoma ikuphi, kusebenza ngokuphelele ukumela ubufakazi balawa ma-magma plumes futhi njengoba kuyisinyathelo sokuqala sokuthi amamephu wokulungiswa okuphezulu abekhona esikhathini esizayo ngenxa yama-satellite anezinzwa ezinamandla adonsela phansi.
Okwamanje yaziwa njengoMhlaba egqinsiwe njengo anyanisi futhi ngaphandle kwaso kukhona izilwandlekazi namazwekazi, kanti ngaphakathi ungqimba lwesambatho lungu-2.900 wamakhilomitha ukushuba. Ngaphansi kwalesi sambatho kukhona ingaphakathi elingaphandle, elenziwe nge-liquid cast iron ne-nickel, emboza insimbi eqinile yangaphakathi enkabeni yeplanethi.
Njengoba konke kumile imfihlakalo ngaphakathi kweplanethi yethu, Kuyisinyathelo sokuqala esithathiwe ukuba nolwazi olungcono sibonga kulawo ma-computer amakhulu asisiza ukukhombisa indlela le magma evela ekujuleni ehamba ngayo.
Uma unayo ilukuluku ukwazi okwengeziwe ngezintaba-mlilo kudlula kuwe ngalokhu kungena ngokungabaza mayelana nesikhathi sayo sonyaka.
