Lub lava no ntsaws cov kav dej hauv stratovolcanoes , tso cai rau lawv tsim kom muaj zog ntau heev. Ntawm tag nrho cov volcanoes hauv ntiaj teb, stratovolcanoes yog cov txaus ntshai tshaj plaws . Lawv tuaj yeem tawg nrog kev ceeb toom me me, tso tawm cov khoom loj heev. Thiab lawv tsis tas yuav tawg zoo nkauj los ntawm lawv cov saum.

Tom qab ntawd, ib tug kuj yuav nug, vim li cas lub roob hluav taws sib xyaw yog qhov txaus ntshai tshaj plaws?

Composite volcanoes yog ib co ntawm cov volcanoes txaus ntshai tshaj plaws nyob ntiaj teb. Lub viscous lava tsis tuaj yeem taug kev deb ntawm ob sab roob hluav taws ua ntej nws solidifies, uas tsim cov ntxhab slopes ntawm ib volcano composite . Viscosity kuj ua rau qee qhov eruptions tawg li tshauv thiab pob zeb me me.

Kuj Paub, vim li cas Stratovolcanoes tawg ntau dua? Stratovolcanoes tuaj yeem tawg nrog kev ua phem loj. Siab tsim nyob rau hauv lub magma chamber li gases, nyob rau hauv loj heev tshav kub thiab siab, yog yaj nyob rau hauv cov kua pob zeb.

Ntxiv mus, dab tsi yog hom hluav taws kub txaus ntshai tshaj plaws thiab vim li cas?

Supervolcano eruptions yog heev tsis tshua muaj nyob hauv ntiaj teb keeb kwm. Nws yog ib qho zoo vim tias lawv loj unimaginably. Lub supervolcano yuav tsum tawg ntau tshaj 1,000 cubic km (240 cubic mais) ntawm cov khoom, piv nrog rau 1.2 km3 rau Mount St. Tsis xav tsis thoob, supervolcanoes yog cov yam txaus ntshai tshaj plaws ntawm lub roob hluav taws.

Dab tsi yog qhov phom sij ntawm Stratovolcanoes?

Stratovolcanoes (tseem hu ua volcanoes sib xyaw) yog tsim los ntawm cov khaubncaws sab nraud povtseg ntawm cov tshauv thiab lava. Lub magma (molten pob zeb) nyob rau hauv lub roob hluav taws yog khov thiab feem ntau muaj daig gas , ua rau tawg tawg. Cov huab ntawm tshauv los ntawm volcanic eruptions ua rau muaj kev phom sij rau aviation.
