Continental crust feem ntau yog tsim los ntawm ntau hom granites. Geologists feem ntau xa mus rau cov pob zeb ntawm lub teb chaws crusts li "sial." Sial stands rau silicate thiab txhuas, cov minerals ntau tshaj nyob rau hauv continental crust.
pob zeb dab tsi ua rau sab av loj?
Cov pob zeb sab av loj yog txheej ntawm granitic, sedimentary, thiab metamorphic pob zeb, uas tsim cov teb chaws thiab thaj chaw ntawm cov seabed ntiav ze ntawm lawv cov ntug dej (cov txee sab av loj).
piv txwv ntawm continental crust yog dab tsi?
Cov pob zeb sab av loj yog txheej ntawm granitic, sedimentary thiab metamorphic pob zebuas tsim cov teb chaws thiab thaj chaw ntawm cov dej hiav txwv ntiav ze ze rau lawv cov ntug dej, hu ua continental txee. Nws yog tsawg dua cov khoom ntawm lub ntiaj teb lub mantle thiab yog li "floats" rau saum nws.
Lub pob zeb twg muaj cov dej hiav txwv dej?
Oceanic crust yog li 6 km (4 mais) tuab. Nws yog tsim los ntawm ob peb txheej, tsis suav nrog cov sediment overlying. Cov txheej saum toj kawg nkaus, txog 500 metres (1, 650 ko taw) tuab, suav nrog lavas ua los ntawm bas alt (uas yog, cov khoom siv pob zeb muaj ntau ntawm plagioclase [feldspar] thiab pyroxene).
Qhov twg yog cov dej hiav txwv tuab dua lossis cov teb chaws Europe?
Lub ntiaj teb lub crust feem ntau muab faib ua laus dua, thicker continental crustthiab yau dua, denser dej hiav txwv crust.
