divergent phaj ciam teb
Ib sab ntawm qhov no, vim li cas Feem ntau cov roob hluav taws pom nyob rau ntawm daim phiaj 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.
Ib yam li ntawd, daim phiaj ciam teb cuam tshuam li cas rau volcanoes? Kev sib tsoo daim hlau daim hlau swb dhau ib leeg ua rau muaj kev sib txhuam thiab kub. Subducting daim hlau yaj nyob rau hauv lub mantle, thiab diverging daim hlau tsim cov khoom siv crust tshiab. Subducting daim hlau , qhov twg ib tectonic phaj yog raug tsav nyob rau hauv lwm, yog txuam nrog roob hluav taws thiab av qeeg.
Yog li ntawd, hom volcanoes pom nyob rau ntawm thaj tsam sib txawv?
Shield volcanoes
Lub roob hluav taws tsim li cas?
Volcanoes yog tsim Thaum magma los ntawm hauv lub ntiaj teb sab sauv mantle ua haujlwm rau saum npoo. Nyob rau saum npoo, nws erupts tsim lava ntws thiab tshauv deposits. Sijhawm dhau los ua tus roob hluav taws txuas ntxiv mus, nws yuav loj dua thiab loj dua.

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
Dab tsi phaj ciam ua daim ntaub thaiv volcanoes?
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.
Dab tsi ntawm daim phiaj ciam teb ua rau muaj av qeeg hauv San Francisco xyoo 1906?
Pacific Phaj (nyob rau sab hnub poob) swb kab rov tav qaum teb sab hnub poob txheeb ze rau North American Phaj (nyob rau sab hnub tuaj), ua rau av qeeg raws San Andreas thiab muaj feem cuam tshuam. Lub San Andreas txhaum yog ib qho kev hloov pauv ntawm ciam teb, ua kom haum rau kab rov tav cov lus tsa suab
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 .
