Lub pob zeb melted no hu ua magma. Thiab txhua yam uas tawg magma yog ib roob hluav taws . Hauv qab roob hluav taws yog cov pas dej loj uas muaj piping kub mush.
Nyob rau hauv no hais txog, dab tsi yog sab hauv ntawm lub roob hluav taws hu ua?
Sill - Ib lub pob zeb tiaj tus tsim thaum magma hardens nyob rau hauv ib qho tawg hauv ib roob hluav taws . Vent - Qhov qhib hauv ntiaj teb qhov chaw los ntawm qhov ntawd roob hluav taws cov ntaub ntawv khiav. Flank - Sab ntawm a roob hluav taws . Lava - Molten pob zeb uas erupts los ntawm ib roob hluav taws uas solidifies thaum nws txias. Crater - Lub qhov ncauj ntawm ib roob hluav taws - ncig a roob hluav taws qhov cua.
Tsis tas li ntawd, dab tsi yog nyob rau hauv volcanic eruption? A volcanic eruption tshwm sim thaum cov khoom kub ntawm lub ntiaj teb sab hauv raug pov tawm ntawm ib roob hluav taws . Lava, pob zeb, plua plav, thiab roj sib txuas yog qee qhov "ejecta". Ib txhia tawg yog cov tawg loj heev uas pov tawm pob zeb loj heev thiab roob hluav taws tshauv thiab tuaj yeem tua ntau tus neeg. Ib txhia yog nyob ntsiag to outflows ntawm kub lava.
Hais txog qhov no, dab tsi tshwm sim hauv qab no thaum lub roob hluav taws tawg?
Volcanoes yog tsim thaum magma (kua pob zeb) daig hauv qab lub ntiaj teb lub crust nce mus rau lub nto thiab khiav los ntawm kev tawg. Qhov chaw rau magma tawm yog me me heev thiab, thaum nws mus ncig, siab tsim, txhais tau tias nws khiav tawm nruj heev thaum tso tawm.
lava puas tuaj yeem tua koj?
Lava yuav tsis tua koj yog nws luv luv kov koj . Koj yuav tau txais ib tug phem hlawv, tab sis tshwj tsis yog koj poob rau hauv thiab tsis tuaj yeem tawm, koj yuav tsis tuag. Cov neeg tau tua los ntawm kev txav ceev heev lava ntws. Ib qho piv txwv tsis ntev los no yog xyoo 1977 tawg ntawm Nyiragongo.
