- Indawo: Alanavori, Madagascar
Ukukhangwa okuyinhloko kweMadagascar kungokwemvelo. Kwenzeke ukuthi impilo lapha ibonakala ikhula ngokusho kwesimo esithile esikhethekile, kanti izinhlobo eziningi eziye zafa ezweni elikhulu ziye zathola lapha indawo ekahle yazo. Kodwa-ke, akukhona nje ngezilwane, futhi akuzona zonke izindawo eziphawulekayo lapha ezidalwe kuphela yimvelo kamama. Endaweni yedolobha lase-Alanavori kunesimangaliso sangempela - i-geyser eyenziwe ngabantu, emangalisa bonke abahambi.
Iyini eyingqayizivele yale ndawo?
Ukufika ensimini yamagesi (futhi kukhona amane kuphela lapha), okokuqala kunzima ukukholelwa ukuthi konke lokhu kubuhle kwenziwa ngumuntu. Futhi isizinda semvelo silula. Eceleni kwama-Analavory kunezimayini ze-argonite. Lokhu kungokwemvelo ukuthi amanzi amaningi atholakala njalo lapha. Ngakho-ke, onjiniyela bendawo bafika esixazululweni esihle: bakha inethiwekhi yamapayipi lapho amanzi ephuma ngaphandle.
Noma kunjalo, ezindaweni eziseduze azikho izintaba-mlilo, azikho izingxenye ezisebenza ngokuzenzekelayo. Kungani abagibeli? Kuyinto elula - ukuphendula kwamakhemikhali evamile. Amanzi angaphansi komhlaba anezinga lokushisa eliphakeme futhi alungiswa ne-carbon dioxide. Ngesikhathi i-liquid iyadlula emayini, ichithe amadwala omlilo. Lapho amanzi egeleza ngokusebenzisa amapayipi ensimbi, i-oxidation yenzeka, ekwakheni i-carbon dioxide ekubunjweni. Ngakho-ke kuvela ukuthi ukukhiqizwa kwekhabhoni dioxide kwenza umphumela ofanayo wokuthi "ukuqhuma", ngenxa yokuthi lokhu kudalwa kokubunjwa kwaba yizici zemvelo. Ukuze ucabange lesi senzo ngokwengeziwe, khumbula ibhodlela ngamanzi amaminerali aqhekezayo. Umphumela uyafana, kuphela okukhudlwana.
Gcwalisa isithombe sezintabeni, ezidwetshwe ngemibala ebomvu ngokubonga konke okufanayo kwamakhemikhali. Ephakeme kakhulu ifinyelela ku-4 m futhi iyaqhubeka ikhula.
Njengomthetho, i-jet yamanzi aphumayo ayidluli ku-30 cm. Kodwa-ke, kwakukhona amacala lapho iphayiphi iguqulwa, futhi ekucindezelekeni kwehlisa i-geyser eyenziwe kahle e-Analavory ibetha kuze kube ngamamitha amabili ukuphakama.
Amapayipi alethwa emfuleni uMazi. Ukucwiliswa ngamanzi amaminerali, ukukhipha, kudala amachibi amancane lapho abantu bendawo baqhuma khona. Kukholelwa ukuthi lokhu kunomthelela omuhle empilweni yonke, ikakhulukazi, kusiza ukuphulukisa ekunganeni.
Izivakashi zimbalwa lapha, futhi umgwaqo ude. Ezindaweni eziseduze, ngaphandle kwama-geysers, akukho lutho okumele lubukele. Kodwa-ke, amaMalagasy ngokwabo le ndawo inencazelo ethile engcwele.
Ungafinyelela kanjani ku-Geyser of Analavory?
I-"Valley of Geysers" eyenziwe ngabantu eyenziwa ngomuntu itholakala ku-12 km ukusuka edolobheni lase-Analavory. Ungathola lapha ngemoto eqashiwe emgwaqweni omkhulu 1B. Uhambo aludluli ngaphezu kwengxenye yehora.
