Kwv yees li 80% ntawm av qeeg tshwm sim qhov twg daim hlau raug thawb ua ke, hu ua convergent ciam teb . Lwm daim ntawv ntawm convergent ciam teb yog kev sib tsoo uas ob sab av loj daim hlau ntsib taub hau. Cov San Andreas Fault yog ib qho piv txwv zoo tshaj plaws ntawm lateral phaj tsab ntawv tsa suab.

Tsis tas li ntawd, hom phaj ciam teb twg yog San Andreas Fault?

hloov

Tom qab ntawd, lo lus nug yog, hom phaj ciam teb yog lub luag haujlwm rau qhib Gulf of California? Nyob rau sab qaum teb kawg ntawm Gulf, ib qho loj hloov txhaum txuas ntxiv mus rau sab qaum teb hnub poob, qhov twg nws txuas nrog lub San Andreas Fault System . Cov East Pacific Rise yog "divergent" phaj ciam teb, qhov twg loj slabs ntawm lub ntiaj teb lub crust (plates) yog txav deb ntawm ib leeg.

Ib yam li ntawd, 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.

Vim li cas San Andreas Fault yog ib thaj tsam hloov pauv?

Raws li North American phaj ntsib lub Pacific phaj qhov txheeb ze ntawm lawv ua rau convergent ciam teb raws li ib feem ntawm cov npoo ntawm North America kom hloov mus rau hauv ib qho hloov ciam teb . Qhov kev txheeb ze no yog qhia raws tus San Andreas hloov qhov txhaum as right-lateral strike-slip offset.
