Thaum twg ob daim phiaj dej hiav txwv sib tsoo , cov denser phaj yog subducted thiab qee cov khoom nce siab thiab daim ntawv ib ISLAND. Dab tsi tshwm sim thaum ob daim phiaj continental sib tsoo ? Cov continental crust raug thawb ua ke thiab nce mus rau saum roob loj.

Ib yam li ntawd, yuav ua li cas tshwm sim thaum ob daim phiaj sab av loj sib sau ua ke?

Hloov chaw, kev sib tsoo ntawm ob daim hlau continental crunches thiab folds lub pob zeb ntawm tus ciam teb, lifting nws thiab ua rau tsim ntawm roob thiab roob.

Tsis tas li ntawd, thaum lub phaj dej hiav txwv thiab lub phaj continental converge? Thaum twg dej hiav txwv pob zeb sib hloov nrog teb chaws Europe crust, lub denser daim phiaj dej hiav txwv plunges hauv qab lub continental phaj . Cov txheej txheem no, hu ua subduction, tshwm sim ntawm lub dej hiav txwv cov trench. Tag nrho cheeb tsam yog hu ua subduction zone. Subduction zones muaj av qeeg hnyav heev thiab volcanic eruptions.

Tsis tas li ntawd, cov ntaub ntawv twg thaum ob daim phiaj av loj sib sau ua ke?

Continental thiab Oceanic Daim phiaj Hloov chaw, continental daim hlau Feem ntau khoov, tawg thiab crumple, tsim folds, tuab creases thiab roob ntau yam xws li Andes, Swiss Alps thiab lub Himalayas. Cov pob zeb uas nyob hauv thaj chaw sib tsoo tau hloov pauv vim qhov kub thiab txias heev.

Qhov tshwm sim ntawm ob daim phiaj continental converging yog dab tsi?

Convergent Phaj Ciam teb - Dej hiav txwv thiab Continental Daim phiaj Thaum twg teb chaws Europe thiab daim phiaj dej hiav txwv sib tsoo, lub thinner thiab ntau ntom daim phiaj dej hiav txwv yog overridden los ntawm thicker thiab tsawg ntom continental phaj . Cov daim phiaj dej hiav txwv raug yuam mus rau hauv lub mantle hauv tus txheej txheem hu ua "subduction."
