Lub stratovolcano yog ib siab, conical volcano muaj li ntawm ib txheej ntawm hardened lava, tephra, thiab volcanic tshauv. Cov roob hluav taws no yog characterized los ntawm ib Ncej profile thiab ntu ntu, tawg tawg. Lub lava uas ntws los ntawm lawv yog siab heev khov , thiab txias thiab hardens ua ntej kis mus deb heev.

Ntawm no, hom volcano twg muaj viscosity siab?

Mauna Loa

Ib yam li ntawd, vim li cas Stratovolcanoes thiaj li tawg? tawg eruptions tshwm sim ntawm stratovolcanoes vim muaj roj ntau hauv cov magma. Raws li cov magma nce, cov roj tso tawm, ua rau lub siab hauv qab lub roob hluav taws nce ntxiv. Thaum lub siab no loj txaus, ib tawg tawg tshwm sim.

Tsis tas li ntawd paub, puas volcanoes puas muaj siab lossis qis viscosity?

Composite Volcanoes Lawv zoo li yuav ua los ntawm felsic rau nruab nrab pob zeb thiab cov viscosity ntawm lava txhais tau hais tias eruptions zoo li tawg. Cov khov lava tsis tuaj yeem taug kev deb ntawm ob sab roob hluav taws ua ntej nws solidifies, uas tsim cov ntxhab slopes ntawm ib tug volcano composite.

Hom kev tawg ua li cas Stratovolcanoes muaj?

Feem ntau tsim nyob rau hauv ib lub sij hawm ntawm kaum mus rau pua pua txhiab xyoo, stratovolcanoes muaj tawg ntau yam magma hom , suav nrog basalt, andesite, dacite, thiab rhyolite. Tag nrho tab sis basalt feem ntau ua kom tawg heev tawg.
