Dej hiav txwv – dej hiav txwv convergence

Hauv kev sib tsoo ntawm ob dej hiav txwv daim hlau, lub cooler, denser dej hiav txwv lithosphere sinks hauv qab lub warmer, tsawg ntom dej hiav txwv lithosphere. Raws li lub slabs tob rau hauv lub mantle, nws tso dej los ntawm lub cev qhuav dej ntawm hydrous minerals nyob rau hauv lub mantle. dej hiav txwv pob zeb.

Tsis tas li ntawd, dab tsi yog qhov piv txwv ntawm oceanic oceanic convergence?

Ib piv txwv ntawm ib dej hiav txwv / dej hiav txwv convergent Ciam teb yog qhov nruab nrab ntawm Pacific thiab Mariana daim phiaj, uas suav nrog Mariana Islands arc thiab a subduction cheeb tsam encompassing Mariana Trench, qhov tob tshaj plaws ntawm lub ntiaj teb Dej hiav txwv.

Tsis tas li ntawd, Oceanic Oceanic thiab Oceanic Continental convergent ciam teb zoo li cas? Lawv ob leeg convergent tsam, tab sis thaum ib dej hiav txwv phaj converges nrog a teb chaws Europe plate, ua dej hiav txwv phaj yog yuam hauv qab lub teb chaws Europe pla vim dej hiav txwv crust yog thinner thiab denser dua teb chaws Europe pob zeb.

Raws li txoj cai, Oceanic Oceanic yog dab tsi?

Thaum continental thiab dej hiav txwv daim hlau sib tsoo, lub thinner thiab ntom dej hiav txwv phaj yog overridden los ntawm thicker thiab tsawg ntom continental phaj. Cov dej hiav txwv phaj raug yuam mus rau hauv lub mantle hauv tus txheej txheem hu ua " subduction ." Raws li cov dej hiav txwv phaj descends, nws raug yuam mus rau qhov kub thiab txias ib puag ncig.

Cov yam ntxwv dab tsi yog tsim ntawm Oceanic rau dej hiav txwv convergent ciam teb?

Sib sib zog nqus dej hiav txwv trenches, volcanoes, kob arcs, submarine roob ranges, thiab cov kab txhaum yog cov piv txwv ntawm nta uas tau daim ntawv nrog phaj tectonic ciam teb . Volcanoes yog ib hom feature uas daim ntawv nrog convergent phaj ciam teb , qhov twg ob daim hlau tectonic sib tsoo thiab ib qho txav hauv qab rau lwm qhov.
