Convergent , divergent thiab hloov ciam teb sawv cev rau thaj chaw uas lub ntiaj teb daim phiaj tectonic cuam tshuam nrog ib leeg. Convergent ciam teb , ntawm uas muaj peb hom, tshwm sim qhov twg daim hlau sib tsoo. Hloov ciam teb tshwm sim qhov twg daim hlau swb dhau ib leeg.

Kuj paub, dab tsi yog convergent divergent thiab hloov ciam teb?

Divergent ciam teb -- qhov twg tshiab crust yog generated raws li daim hlau rub tawm ntawm ib leeg. Convergent ciam teb -- qhov twg crust raug puas ntsoog raws li ib lub phaj dives nyob rau hauv lwm. Hloov ciam teb - qhov twg crust tsis yog tsim los yog puas tsuaj raws li daim hlau swb horizontally dhau ib leeg.

Kuj Paub, hom kev quab yuam twg cuam tshuam nrog ib thaj tsam sib txawv? Divergent Phaj Boundary - Oceanic Thaum a ciam teb sib txawv tshwm sim hauv qab dej hiav txwv lithosphere, qhov nce convection tam sim no hauv qab nqa lub lithosphere, ua rau nruab nrab dej hiav txwv ridge. Extensional zog stretch lub lithosphere thiab tsim ib tug sib sib zog nqus fissure.

Qhov thib ob, dab tsi tshwm sim ntawm convergent thiab divergent phaj ciam teb?

A txawv txawv ciam teb tshwm sim thaum ob tectonic daim hlau txav deb ntawm ib leeg. Ntawm convergent phaj ciam teb , dej hiav txwv crust feem ntau raug yuam mus rau hauv lub mantle uas nws pib yaj. Magma nce mus rau hauv thiab dhau ntawm lwm yam phaj , solidifying rau hauv granite, lub pob zeb uas ua rau lub teb chaws.

Yuav ua li cas hloov ciam teb thiab divergent ciam teb zoo sib xws?

Kev piav qhia: Divergent ciam teb yog qhov twg ob daim phiaj tectonic txav deb ntawm ib leeg, cia lub mantle ntws mus thiab tsim cov lithosphere tshiab. Hloov ciam teb yog qhov twg ob daim phiaj tectonic txav dhau ib leeg, thiab lawv tsis tsim lossis rhuav tshem lithosphere.
