Iyini imbangela kuqhuma intaba-mlilo

Ngaphambi ukuthola ukuthi kunani imbangela ukuqhuma kwentaba-mlilo, kudingeka uqonde ukuthi limelela. Ngokwe amagama yale nqubo kuba umsebenzi asebenzayo mlilo, ethwala ingozi enkulu kunoma uhlobo lokuphila ngenxa ukukhululwa okukhulu ebusweni umlotha lava imfucumfucu incandescent. kuqhuma Kugcine ayengase amahora amabili noma amathathu kuya eminyakeni eminingana. Kukhona amacala lapho magma ayaphola phansi emgodini wentaba, nga which he bungeke. Isayensi okwamanje labelwe izinhlobo ezinjalo ka mlilo, njengoba Hawaiian, Strombolian, vezuviansky futhi Dome.

Akusiyo imfihlo ukuthi lembulunga yethu kungaqali egxilile ngokuphelele, futhi ngaphansi kwesikhumba (yaziwa njenge lithosphere) mayelana ayisishiyagalombili amakhilomitha awugqinsi, wembozwe isiphuku. Kuyinto kule amanga isizathu esiyinhloko ukuqhuma kwenzeka intaba-mlilo. Iqiniso liwukuthi i-lithosphere ihlanganiswa ngokuphelele amaphutha. Ngesikhathi esifanayo izinga lokushisa isiphuku Izinga latinkhulungwane letinyentana. Futhi indlela umnyombo, ukhula. Ngenxa umehluko lokushisa hot lava uquqaba ezihambayo phezulu, amakhaza, kunalokho, ivinjelwe.

Manje amagama ambalwa mayelana nendlela ukuqhuma intabamlilo. Lapho kushisa, kodwa epholisa le lithosphere isiphuku ngezansi ezingeni leliphasi, kusenzima abanye uhamba isikhathi ngaphansi kwaso nendawo ezihambayo amapuleti lithospheric. Kufanele kuqashelwe ukuthi izingcezu naphula kude nawo. Njengoba nje enye ipuleti aqala ukuba omunye, ephansi is egxilile isembatho iqala igcwale amanzi. Kusukela magma kuyinto isisindo ingasaphathwa nje uma eqhathaniswa naso esikhipha yamadwala, kancane kancane liqala ukuphakama phezulu bese buthelela ku foci kangaka okuthiwa. Ngokuhamba kwesikhathi, umthamo yayo ukwanda, futhi ifuna inkululeko awusakufuni ufa ku lithosphere. Ngokuhamba kwesikhathi, ungqimba lomhlaba ezindaweni umpofu kuqubuka, kanti magma uyaphuma.

Isizathu sokuba kuqhuma intaba-mlilo ngokuyinhloko ezimboziwe e magma degassing. Iqiniso lokuthi yilokho esigxila kukho lapho ingaphansi kwengcindezi okusezingeni eliphezulu. Kulezo zindawo lapho okuthiwa emhlabeni ipulaki kuqhathaniswa ababuthakathaka, kunomqubuko. Kule nqubo, i-magma ilahlekelwa amagesi. Ziyakwazi oluvuthayo, ngakho wentaba umlilo futhi zibamba umlilo. Ngezinye izikhathi magma ongasitholi esidayisa ku surface eMhlabeni. Kulokhu, kusukela lava wentaba-mlilo nje ageleza. Ngezinye izikhathi kancane kancane nje epholisa at ukujula.

Summing phezulu, kufanele kuphawulwe ukuthi isizathu esiyinhloko esenza ngoba ukuqhuma - ukukhululwa of magma kusukela izikhungo kwezine zobukhulu bomhlaba ebusweni ngenxa ukuhamba lithospheric amapuleti futhi ophezulu. Uma yinhlama entsha izidakamizwa ashisayo azitholakali, intaba-mlilo angakwazi ukulala unomphela. Uma emaphaketheni uyogcwala futhi, ngeke aqhubeke nomsebenzi walo.

mlilo ngokuvamile iholela ekufeni kwabantu nezilwane, kanye ukubhujiswa abalulekile kwezakhiwo kanjalo nezinhlaka. Lava nezinye izidakamizwa red-hot ugeleza phansi emaceleni ale ntaba nokusha konke endleleni yayo. Kungakhathaliseki ukuthi kude seziphelile ukuthuthukiswa wesintu, abaleke kuqhuma kuphela namanje ephelele kuhlengwe abantu.
