Divergent (Kev Tshaj Tawm): Nov yog ob qho daim hlau txav deb ntawm ib leeg. Convergent ( Kev sib tsoo ): Qhov no tshwm sim thaum daim hlau sib ncaim mus thiab sib tsoo . Thaum lub continental phaj ntsib ib tug dej hiav txwv phaj , lub thinner, denser, thiab hloov tau yooj yim dej hiav txwv phaj dab dej hauv qab lub thicker, nruj dua continental phaj.

Kuj nug, ua li cas thaum daim hlau sib txawv?

Ib thaj tsam sib txawv tshwm sim thaum ob tectonic daim hlau txav deb ntawm ib leeg. Raws li cov ciam teb no, av qeeg muaj ntau thiab magma (molten pob zeb) nce los ntawm lub ntiaj teb lub mantle mus rau saum npoo, solidifying tsim tshiab oceanic crust. Thaum ob daim hlau tuaj ua ke, nws yog hu ua convergent ciam teb.

Tsis tas li ntawd, kev sib tsoo phaj ciam teb ua rau dab tsi? Cov daim hlau txav mus rau ib leeg thiab qhov kev txav no tuaj yeem ua rau av qeeg thiab volcanoes. Raws li cov daim hlau sib tsoo , dej hiav txwv phaj raug yuam hauv qab lub teb chaws phaj . Qhov no yog lub npe hu ua subduction thiab ua rau tsim ib qho dej hiav txwv trench.

Kuj tseem yuav paub yog, cov qauv av twg tuaj yeem yog qhov tshwm sim ntawm diverging daim hlau?

Ob daim av uas yog tsim los ntawm cov ciam teb sib txawv yog rift kwj ha thiab nruab nrab - hiav txwv ridges.

Puas yog San Andreas Fault divergent lossis convergent?

Divergent faults tsim qhov khoob lossis sags. Thaum daim ntawv ciam teb yog convergent yeej ib txwm muaj subduction zone. Thaum twg sib txawv , lawv feem ntau qhib kwj ntawm av thiab dej hiav txwv ridges zoo li Mid Atlantic Ridge. Cov San Andreas Fault yog ib qho chaw uas ob daim hlau tectonic kov, North American thiab Pacific Phaj.
