Tectonic lithosphere daim hlau muaj lithospheric mantle overlain los ntawm ib los yog ob hom ntawm pob zeb khoom siv: dej hiav txwv pob zeb (hauv cov ntawv qub hu ua sima los ntawm silicon thiab magnesium) thiab continental pob zeb (sial los ntawm silicon thiab aluminium).

Tom qab ntawd, ib tug kuj yuav nug, dab tsi yog cov 7 crustal daim hlau?

Lub plhaub sab nraud ntawm lub ntiaj teb, lub lithosphere, tawg mus rau hauv daim phiaj tectonic. xya daim phiaj loj yog cov African phaj , Antarctic phaj , Eurasian phaj , Indo-Australian phaj, North American phaj , Pacific phaj thiab South American phaj.

Tsis tas li ntawd, 12 daim phiaj loj yog dab tsi? Thawj daim phiaj

• African phaj.
• Antarctic phaj.
• Indo-Australian phaj.
• North American phaj.
• Pacific phaj.
• South American phaj.
• Eurasian phaj.

Tsis tas li ntawd, cov phaj crustal nqa dab tsi?

Nyob rau tib lub sijhawm, qhov saum npoo ntawm lub ntiaj teb txias thiab tawv. Cracks tsim nyob rau hauv lub hardened nto, tsim loj loj daim hlau ntawm pob zeb. Cov no daim hlau nqa cov continents thiab ua nyob rau hauv dej hiav txwv pem teb, floating zoo li cov Islands tuaj ntawm kub, taffylike pob zeb hauv qab no.

Lub npe ntawm lub phaj crustal thiab lub hiav txwv loj yog dab tsi?

Oceanic crust yog txuas ntxiv tsim nyob rau hauv nruab nrab ntawm dej hiav txwv ridges. Raws li daim hlau sib txawv ntawm cov ridges, magma nce mus rau hauv lub tsho loj thiab crust. Raws li nws txav deb ntawm lub ridge, lub lithosphere ua txias thiab denser, thiab sediment maj mam ua rau saum nws.
