E- Australia, akukho ziqhumane eziqhutyayo: ilizwekazi "liphumla" kwi-slab eqinile, ngoko akukho msebenzi we-geological e-Australia malunga neminyaka eyi-1.5 yezigidi-ngokungafani nePolynesia, ummelwane osondeleyo wase-Australia, apho iindawo eziphambili zeMouna Loa kunye neMauna Kea .
Ngaba zikho na iipropano e-Australia?
E-Australia, iindawo ezinokuqhutyelwa kweentaba-mlilo "zabamelwane" zihambisa iingxaki ezimbalwa - zize zifikelele kwilizwe. Into kuphela enokuchaphazela umsebenzi we-tectonic of volcano kwiindawo ezisemaphandleni yinkcitho yegesi ukusuka kwirelufini yonxweme.
Ukuba ucinga i-Australia kungekhona njengelizwekazi, kodwa njengesizwe, kufuneka ukhumbule ukuba iquka iziqithi zasePolynesia nase-Oceania. Ngoko ke, impendulo kumbuzo othi "Ngaba kukho iipropano e-Australia" ziya kuba neempembelelo. Kodwa uluhlu lweentaba-mlilo eziphelile e-Australia zikhulu kakhulu; kubandakanya izikhukhula eziyi-18, ezifana ne-Atherton (kwintlambo yalo namhlanje isixeko sase-Atherton, le ntaba-mlilo yayiphumelele ngokutsha nje - nje kwiminyaka eyi-100 eyadlulayo), i-Barrin ne-Ichem (kwii-craters zabo zinegama elifanayo kwelabi), i-Hillsborough, Bundaberg nabanye.
Mawson
I-4000 km ukusuka e-Australia yi siqithi sase-Heard, esiyi-basalt stratovolcano Mawson (unegama elinye - "Big Ben"). I-Mawson yi-volcano esebenzayo: ukuqhuma kwayo kubhalwe ngo-1881, 1910, 1950-1954, 1984-1985, 1993, 2000. Ukugqibela ukuqhuma komhla kwenzeka ngoMeyi 2006 ukuya kuNovemba 2007.
Uthiwa nguMawson ngokuhlonipha i-geologist yase-Australia, umhloli we-Antarctica uDouglas Mawson. Le mlilo iphakama ngaphezu kwezinga elwandle ukuya kwindawo ephakamileyo ye-2745 m (yiyona ndawo ephezulu ye-Australia). Isitampu esincinci sidibanisa iMawson kunye nomlilo onqabileyo uDickson.
Isiphaluka esingaphantsi komhlaba seentaba-mlilo kwilizwekazi lase-Australia
Ngo-2015, incwadi kaCnet yashicilela iziphumo ezifunyenwe yiqela eliphando elikhokelwa nguRodi Davis: I-Australia ifunyenwe ihlabathi elide kunayo yonke i-continental chain of volcanoes. Ubungakanani bekhenkethi luyiikhilomitha ezili-2 eziliwaka, phantse ubude obuphindwe kabini ngaphezu kobude be-chainstone yangaphandle.
Uluhlu lweentaba-mlilo, olwalufumana igama elithi "Umzila weengqumbo," uwela ngapha kwelo phesheya malunga nelizwe. Yakhiwe ngenxa yesigxina selizwekazi (ngexesha lokutshintshwa kwayo) phezu kwendawo yokuqhuma kwentaba yomlilo kwisitya sehlabathi. Ubude abuyena nje kuphela umdla obonisa umdlalo we "Campfire Trail": ufumaneke ngokwaneleyo kwi-plate ticonic apho i-continent yase-Australia ihlala khona, ngoko ke ityuniti ithatha ingqwalaselo eyongeziweyo yenzululwazi: bakholelwa ukuba isifundo sayo sinokukhanyisa iinkqubo zelizwekazi.
IiVolcanic Islands zaseAustralia
I-770 km ukusuka eSydney iyisiqithi se-volcanic seHowe Howe, isiqithi esiphezulu kunazo zonke sePacific Ocean; yaqulunqwa ngenxa yokuhlanganiswa kweziqithi ezimbini. Kwimizuzu engama-20 ukusuka kuyo kukho esinye isiqithi se-volcanic, iBols-Pyramid (zombini iziqithi zavulwa ngokukodwa, ngo-1788). I-Bol-Pyramid iyona ephezulu kuyo yonke intaba-mlilo, ukuphakama kwayo kukuyi-562 m ngaphezu kwinqanaba lolwandle. Namhlanje isiqithi siyinxalenye yeNkosi Howe Marine Park.
