sib txawv
Raws li txoj cai, qhov chaw thaiv hluav taws xob feem ntau tsim?
Shield volcanoes muaj nyob thoob ntiaj teb. Lawv ua tau daim ntawv hla cov hotspots (cov ntsiab lus uas magma los ntawm hauv qab lub qhov dej ntws), xws li Hawaiian-Emperor seamount chain thiab Galápagos Islands, los yog ntau tshaj qhov chaw sib cais, xws li Icelandic daim thaiv thiab cov tiv thaiv volcanoes ntawm East Africa.
Yuav ua li cas volcanoes tsim ntawm phaj ciam teb? Volcanoes muaj ntau nrog tectonic phaj ciam teb qhov twg dej hiav txwv daim hlau tog hauv qab daim hlau . Raws li ib tug phaj sinks tob rau hauv ib cheeb tsam subduction, nws heats thiab pib yaj, tsim magma. Volcanoes kuj muaj raws li tectonic ciam teb qhov twg daim hlau rub sib nrug, cia magma sawv los ntawm lub mantle.
Tsis tas li ntawd, dab tsi phaj ciam ua Stratovolcanoes tsim?
Stratovolcanoes feem ntau pom muaj nyob nrog subduction aav , uas yog ciam teb ntawm ob daim phiaj tectonic uas ib lub phaj dej hiav txwv nkag mus rau hauv lub mantle hauv qab lwm phaj tectonic.
Lub roob hluav taws loj tshaj plaws yog dab tsi?
Mauna Loa . Hawaii ob lub roob hluav taws loj tshaj plaws yog Mauna Loa (hauv keeb kwm yav dhau los rau S) thiab Mauna Kev.

Dab tsi phaj ciam ua rau faults?
Rov qab faults tshwm sim ntawm convergent phaj ciam teb, thaum ib txwm faults tshwm sim ntawm divergent phaj ciam teb. Av qeeg nyob rau hauv kev tawm tsam-plam qhov txhaum ntawm kev hloov pauv cov ciam teb feem ntau tsis ua rau tsunami vim tias muaj me me lossis tsis muaj kev txav ntsug
Cov volcanoes twg nyob rau ntawm convergent phaj ciam teb?
Volcanoes ntawm convergent phaj ciam teb yog pom nyob rau hauv lub Pacific hiav txwv phiab, feem ntau nyob rau ntawm ntug dej hiav txwv Pacific, Cocos, thiab Nazca daim hlau. Trenches cim subduction zones. Cov Cascades yog cov saw hlau ntawm cov hluav taws kub ntawm ib thaj tsam sib koom ua ke qhov twg cov phaj dej hiav txwv yog subducting hauv qab daim phiaj av
Puas yog volcanoes nyob rau ntawm daim phiaj ciam teb?
Volcanoes yog ib tug vibrant manifestation ntawm phaj tectonics txheej txheem. Volcanoes muaj nyob rau hauv convergent thiab divergent phaj ciam teb. Volcanoes kuj pom nyob rau hauv daim phiaj lithospheric deb ntawm phaj ciam teb. Volcanoes tawg vim mantle pob zeb melts
Txoj kev faib cov ntaub ntawv twg muab cov ntaub ntawv sib npaug ntawm cov ntaub ntawv lossis cov kev tshuaj xyuas hauv txhua chav kawm cov ntaub ntawv?
Quantile. txhua chav kawm muaj cov yam ntxwv sib npaug. Ib qho kev faib tawm ntau yog zoo haum rau cov ntaub ntawv faib tawm. Quantile muab tib tus lej ntawm cov ntaub ntawv muaj nuj nqis rau txhua chav kawm
Dab tsi ntawm tectonic phaj ciam teb yog Mount Pinatubo rau?
Eurasian Hauv qhov no, hom phaj ciam teb yog Mount Pinatubo nyob rau? Mount Pinatubo nyob rau ntawm ib thaj tsam ntawm Continental Eurasian thiab Oceanic Philippine phaj . Lub Oceanic Philippine phaj tab tom raug thawb hauv qab lub teeb Continental Eurasian phaj .
