Extrusive igneous pob zeb
Ntxiv mus, dab tsi yog qhov nruab nrab igneous pob zeb?
Nruab nrab pob zeb yog roughly txawm mixs ntawm felsic minerals (tsuas yog plagioclase) thiab mafic minerals (tsuas yog hornblende, pyroxene, thiab/los yog biotite). Muaj me me lossis tsis muaj quartz. Felsic pob zeb feem ntau yog feldspar (tshwj xeeb tshaj yog K-feldspar), tsawg kawg yog 10% quartz, thiab tsawg dua 15% mafic minerals (biotite, hornblende).
Ib yam li ntawd, dab tsi yog lwm lub npe rau igneous pob zeb? Igneous pob zeb kuj paub los ntawm npe plutonic thiab volcanic pob zeb . Plutonic pob zeb yog lwm lub npe rau intrusive igneous pob zeb.
Ua raws li qhov no, dab tsi yog 2 hom pob zeb igneous?
Igneous pob zeb yog tsim los ntawm lava los yog magma. Magma yog molten pob zeb uas yog underground thiab lava yog molten pob zeb uas erupts tawm ntawm qhov chaw. Cov ob lub ntsiab hom pob zeb igneous yog plutonic pob zeb thiab pob zeb volcanic . Plutonic pob zeb yog tsim thaum magma txias thiab solidifies underground.
Koj tuaj yeem qhia dab tsi txog lub pob zeb uas tsis muaj zog uas yog ntxhib grained?
Nplej qhov loj ua tau sib txawv heev, los ntawm heev coarse grained pob zeb nrog crystals qhov luaj li cas ntawm koj lub nrig, nqes mus rau cov khoom siv iav uas txias sai sai uas tsis muaj cov ntxhia nplej tag nrho. Coarse nplej ntau yam (nrog cov ntxhia nplej loj txaus kom pom yam tsis muaj iav magnifying) hu ua phaneritic.

Lub npe ntawm lub raj los ntawm cov pob zeb molten ntws yog dab tsi?
Lub raj lava tsim thaum lub npoo ntawm lava txias thiab tawv, thaum lub molten sab hauv ntws los ntawm thiab ntws tawm. 21. Tshauv yog qhov thib ob tsawg tshaj plaws pyroclast
Lub npe ntawm cov enzyme uas catalyzes ntawm cov synthesis ntawm mRNA Strand yog dab tsi?
MRNA yog "tus tub txib" RNA. mRNA yog synthesized nyob rau hauv lub nucleus siv cov nucleotide ib theem zuj zus ntawm DNA ua ib tug template. Cov txheej txheem no yuav tsum muaj nucleotide triphosphates ua substrates thiab yog catalyzed los ntawm enzyme RNA polymerase II. Tus txheej txheem ntawm kev ua mRNA los ntawm DNA yog hu ua transcription, thiab nws tshwm sim nyob rau hauv lub nucleus
