Ku Australia, kulibe mapiri otentha: dziko lonse lapansi "limapuma" pa dothi lolimba, kotero palibe malo ozungulira ku Australia kwa zaka pafupifupi 1.5 miliyoni - mosiyana ndi Polynesia, woyandikana naye pafupi kwambiri wa Australia, kumene Mauna Loa ndi Mauna Kea .
Kodi pali mapiri ku Australia?
Australia, mapiri otentha a "oyandikana nawo" amapereka mavuto angapo - amangobwerera kumtunda. Chinthu chokha chomwe chingakhudze mtundu wa tectonic wa mapiri m'mbali mwa nyanja ndi kuchotsedwa kwa gasi kuchokera m'mphepete mwa nyanja.
Ngati mukuganiza Australia osati monga kontinenti, koma monga boma, muyenera kukumbukira kuti zikuphatikizapo zilumba za Polynesia ndi Oceania. Choncho, yankho la funso lakuti "Kodi pali mapiri onse ku Australia" adzakhala abwino. Koma mndandanda wa mapiri akutha ku Australia ndi ochuluka kwambiri; imaphatikizapo mapiri 18, monga Atherton (pamapiri ake lerolino ndi mzinda wa Atherton, phirili linaphulika posachedwa - zaka pafupifupi 100,000 zapitazo), Barrin ndi Ichem (m'mabwinja awo tsopano ali ndi dzina lomwelo la nyanja), Hillsborough, Bundaberg ndi ena.
Mawson
4000 km kuchokera ku Australia ndi chilumba cha Heard, chomwe ndi basalt stratovolcano Mawson (ali ndi dzina lina - "Big Ben"). Mawson ndi phiri lotentha: mapulaneti ake analembedwa mu 1881, 1910, 1950-1954, 1984-1985, 1993, 2000. Kutha kwadutsa kumeneku kukuchitika kuyambira May 2006 mpaka November 2007.
Amatchedwa Mawson kulemekeza mlengalenga wa ku Australia, wofufuza za Antarctica Douglas Mawson. Mphepoyi ikukwera pamwamba pa nyanja mpaka kufika mamita 2745 (ndiyo malo apamwamba kwambiri a dziko la Australia). Dera lophatikizana limagwirizanitsa Mawson ndi Dickson pafupi ndi phiri.
Mphepete mwapansi pa mapiri a ku Australia
Mu 2015, buku la Cnet linasindikiza zotsatira zomwe gulu lofufuza lomwe linatsogoleredwa ndi Rodi Davis: Australia yapezeka mkokomo wa mapiri aatali kwambiri padziko lonse lapansi, wobisika pansi pa nthaka. Kutalika kwa unyoloyi ndi makilomita 2,000, pafupifupi nthawi ziwiri kuposa kutalika kwa mzere wa Yellowstone subterranean.
Mphepete mwa mapiri, omwe analandira dzina la ndakatulo lakuti "Trail of Fires," limadutsa gawo lakummawa kwa dzikoli pafupifupi kwathunthu. Iyo inakhazikitsidwa chifukwa cha ndime ya dziko lapansi (panthawi yake yosunthira) pachithunzi chowoneka chophulika mu chovala cha padziko lapansi. Kutali sikuti ndi chinthu chokha chochititsa chidwi cha "Campfire Trail": Chilinso chokwanira kwambiri kuchokera ku tectonic mbale yomwe dziko la Australia likukhazikika, kotero kuti unyolo umakopa chidwi cha asayansi: amakhulupirira kuti phunziro lake lingathe kuwunikira kayendedwe ka kayendetsedwe ka makontinenti.
Volcanic Islands za ku Australia
770 kuchokera ku Sydney ndi chilumba cha Ambuye Howe, chomwe ndi chilumba chakale kwambiri cha Pacific Ocean; iyo inakhazikitsidwa chifukwa cha kugwirizana kwa zilumba ziwiri za mapiri. Mu makilomita 20 kuchokera pamenepo kuli chilumba chinanso chophulika kwambiri, Bols-Pyramid (zizilumba zonsezo zinatsegulidwa nthawi imodzi, mu 1788). Mpiramidi wa Bol ndi malo okwera kwambiri a mapiri, pamwamba pake ndi mamita 562 pamwamba pa nyanja. Lero chilumbachi ndi mbali ya Ambuye Howe Marine Park.
