Stratovolcanoes

Ib yam li ntawd, tib neeg nug, hom magma pom nyob rau ntawm thaj chaw sib cais?

Feem ntau eruptions pib ntawm qhov ua siab tshaj thiab rift aav ntawm Hualalai, Maunaloa, thiab Kīlauea. Rift aav yog thaj chaw uas lub roob hluav taws nyob kev rifting los yog sib cais. Pob zeb hauv a rift tsam muaj ntau cov kab nrib pleb thiab kuj tsis muaj zog, thiab yog li nws yog qhov yooj yim tshaj rau magma kom nws txoj kev mus rau saum npoo los ntawm cov no rift aav.

Tom qab ntawd, lo lus nug yog, hom hluav taws kub dab tsi tshwm sim ntawm thaj tsam sib txawv? Magma muaj pes tsawg leeg txiav txim siab ob hom eruption thiab volcano hom. Composite volcanoes muaj nyob rau hauv convergent ciam teb. Shield volcanoes yog tsim nyob rau hauv divergent phaj ciam teb thiab intraplate. Cinder cones yog ua los ntawm cov khoom me me ntawm ntau hom kev sib xyaw feem ntau los ntawm ib qho kev tawg.

Tib neeg kuj nug tias, hom ciam teb yog thaj tsam li cas?

sib txawv ciam teb

Qhov chaw tectonic feem ntau yog volcanoes txuam nrog?

Volcanoes feem ntau muaj nyob rau hauv cov geologically active ciam teb. Ob hom phaj ciam teb uas feem ntau yuav tsim volcanic kev ua ub no yog divergent phaj ciam teb thiab convergent phaj ciam teb. Ntawm ib thaj tsam sib txawv, daim phiaj tectonic txav sib nrug ntawm ib leeg.
