Volcanoes ntawm convergent phaj ciam teb yog pom nyob rau hauv tag nrho cov Pacific Dej hiav txwv phiab, feem ntau ntawm cov npoo ntawm lub 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 uas cov phaj dej hiav txwv yog subducting hauv qab daim phiaj av.

Tom qab ntawd, ib tug kuj yuav nug, yog vim li cas volcanoes pom nyob rau hauv convergent ciam teb?

Volcanoes yog pom ntawm convergent phaj ciam teb vim melting tshwm sim los ntawm subduction, thiab ntawm divergent phaj ciam teb vim kev tso siab.

Ib yam li ntawd, nyob qhov twg hauv lub ntiaj teb no yog convergent phaj ciam teb nyob? Piv txwv ntawm Convergent ciam teb West ntug dej hiav txwv ntawm South America yog ib convergent ciam teb nruab nrab ntawm lub Nazca Phaj thiab South American Phaj . Kev sib tsoo ntawm no dej hiav txwv thiab continental phaj yog li cas lub roob Andes tau tsim. Convergent ciam teb tuaj yeem tsim cov Islands tuaj.

Ib yam li ib tug yuav nug, puas yog Mount St Helens convergent phaj ciam teb?

Helens zaum ntawm phaj ciam teb ntawm Juan de Fuca thiab North American daim hlau (daim ntawv qhia saum toj). Cov phaj npoo uas tsim Mount St . Helens yog kev puas tsuaj, nrog Juan de Fuca phaj subducting hauv qab North American, tsim cov kab hluav taws xob raws li Cascade Roob Ntau yam.

Dab tsi ntawm daim phiaj ciam teb feem ntau volcanoes tshwm sim 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 si 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.
