<prompt> Fingqa isihloko: CNN Le meteorite enkulu yahlukana kabili ngaphambi nje kokuba ishaye uMhlaba, yabulala inqwaba yezinhlobo zezinto eziphilayo. Lesi senzakalo esishaqisayo senzeka emhlabeni wethu eminyakeni eyizigidi eziningi edlule, kodwa abacwaningi baqala nje manje ukuthola ukuthi kwenzekani. Engxenyeni ekude ye-Australia Ephakathi, izingcezu ezimbili ze-asteroid zashiya lokho izazi ze-geophysics ezikushoyo ukuthi yindawo enkulu kunazo zonke eyake yatholakala eMhlabeni, ehlanganisa indawo engamakhilomitha angu-400 ububanzi. Lezi zinkanyezi ezincane ezimbili kumelwe ukuba ngayinye yayingaphezu kwamakhilomitha ayishumi ububanzi - kwakuyoba umgoqo ezinhlotsheni eziningi zokuphila kule planethi ngaleso sikhathi, kusho umcwaningi oholayo u-Andrew Glikson wase-Australian National University. Leli qembu lanyathelisa ucwaningo lwalo kumagazini i - Tectonophysics kule nyanga. Umgodi owabangelwa ama-asteroid wanyamalala kudala. Kodwa uGlikson wathi abacwaningi bazithela phezu kwezibazi ezivela emiphumeleni yokushayisana lapho beqombola ucwaningo lwe-geothermal. Izimpande zengcwatshwe ngaphezu kwamakhilomitha amabili ngaphakathi kweGobolondo Lomhlaba, ngaphansi kwendawo eseduze nemingcele yeNingizimu Australia, iQueensland neNorthern Territory. Kunezigodlo ezimbili ezinkulu ezijulile emhlabathini, ezakhiwe umhlabathi womhlaba owabuya ngemva kokushayisana okukhulu, futhi okwenza ukuba idwala liphume ngaphansi, kusho uGlikson. Abacwaningi basalokhu bezama ukuthola ukuthi lesi senzakalo esishaqisayo senzeka nini. Amatshe azungezile aneminyaka eyizigidi ezingu-300 kuya kwezingama-600 ubudala, ngokusho kwethimba, kodwa abakwazanga ukuthola uhlobo lobufakazi obushiywe okunye ukushayeka kwemeteorite. Ukushayisana okukhulu kwesiphepho okukholelwa ukuthi kwaholela ekuqothulweni kwezinhlobo eziningi zama-dinosaur eminyakeni eyizigidi ezingu-66 edlule kwakhipha umlotha womlotha emoyeni manje obonakala njengengqimba yezinsalela emadwaleni. Kodwa abacwaningi bathi abakaze bahlangabezane nohlobo olufanayo lwama-sediment aneminyaka engaba yizigidi ezingu-300 ubudala. Kuyindida - asikwazi ukuthola isenzakalo sokushabalala esifana nalezi zingxabano. Nginokusola ukuthi umthelela ungaba neminyaka engaphezu kwezigidi ezingu-300 ubudala, kusho uGlikson. Ukutholakala kwemiphumela emikhulu ye-asteroid kungenza...  <response>: Izingcezu ezimbili ze-asteroid zawela e-Australia eminyakeni eyizigidi eziningi edlule. Abacwaningi bazithela phezu kwemikhondo yendawo yokuhlasela ekujuleni komhlabathi.
