Muaj peb hom pob zeb : igneous, sedimentary, thiab metamorphic. Igneous pob zeb form thaum molten pob zeb (magma los yog lava) txias thiab solidifies. Sedimentary pob zeb originate thaum hais tawm ntawm dej los yog huab cua, los yog los ntawm nag lossis daus ntawm minerals los ntawm dej. Lawv sau nyob rau hauv txheej.
Ua raws li qhov no, yuav ua li cas pob zeb tsim?
Pob zeb feem ntau muab faib ua peb pawg loj: igneous pob zeb , metamorphic pob zeb thiab sedimentary pob zeb. Pob zeb tsim lub ntiaj teb txheej txheej txheej, lub crust. Igneous pob zeb yog tsim thaum magma txias nyob rau hauv lub ntiaj teb lub crust, los yog lava txias rau hauv av los yog seabed.
Ib yam li ntawd, pob zeb txhais li cas? Kev txhais lus rau pob zeb Ib qho nyuaj, ib txwm tshwm sim cov khoom siv ntxhia. Pob zeb tuaj yeem muaj cov ntxhia pob zeb lossis ntau cov ntxhia uas yog nruj nruj los yog tuav ua ke los ntawm cov cement zoo li pob zeb matrix. Peb hom tseem ceeb ntawm pob zeb yog igneous, sedimentary, thiab metamorphic.
Tsis tas li ntawd, cov pob zeb metamorphic tau tsim li cas?
Metamorphic pob zeb yog tsim los ntawm lub cev los yog tshuaj Hloov los ntawm tshav kub thiab siab ntawm cov khoom uas twb muaj lawm igneous los yog sedimentary rau hauv daim ntawv denser.
Puas yog pob zeb ciaj sia?
Lub npe qee zaum ua rau kev nkag siab yuam kev, raws li "nyob pob zeb "Nws tus kheej tsis yog tiag ciaj sia , tab sis tsuas yog ua los ntawm aragonite skeletons ntawm ntev tuag corals, los yog lwm yam kab mob calcareous, uas nyob rau hauv dej hiav txwv tsim feem ntau ntawm coral reefs.

Yuav ua li cas 3 hom pob zeb tseem ceeb tsim?
Muaj peb hom pob zeb loj: Metamorphic, Igneous, thiab Sedimentary. Metamorphic Pob Zeb - Cov pob zeb Metamorphic yog tsim los ntawm cov cua kub thiab siab. Lawv feem ntau pom nyob rau hauv lub ntiaj teb crust qhov twg muaj cua sov txaus thiab siab los tsim cov pob zeb. Qhov no hardened magma los yog lava yog hu ua igneous pob zeb
Dab tsi yog pob zeb tsim cov ntxhia pob zeb?
Cov pob zeb tsim cov zaub mov yog: feldspars, quartz, amphiboles, micas, olivine, garnet, calcite, pyroxenes. Minerals tshwm sim nyob rau hauv ib lub pob zeb nyob rau hauv me me yog hu ua "accessory minerals"
Dab tsi yog txheej txheem ntuj tsim ua rau ib hom pob zeb hloov mus rau lwm hom?
Peb hom pob zeb tseem ceeb yog igneous, metamorphic thiab sedimentary. Peb txheej txheem uas hloov ib lub pob zeb mus rau lwm qhov yog crystallization, metamorphism, thiab yaig thiab sedimentation. Txhua lub pob zeb tuaj yeem hloov mus rau lwm lub pob zeb los ntawm kev dhau los ntawm ib lossis ntau dua ntawm cov txheej txheem no. Qhov no tsim lub voj voog pob zeb
Yuav ua li cas lub pob zeb sedimentary ua ib lub pob zeb metamorphic?
Sedimentary pob zeb ua metamorphic nyob rau hauv lub pob zeb voj voog thaum lawv raug tshav kub thiab siab los ntawm faus. Cov kub kub yog tsim thaum lub ntiaj teb daim hlau tectonic txav ib ncig, ua kom sov. Thiab thaum lawv sib tsoo, lawv tsim roob thiab metamorphose
Cov pob zeb hauv av twg tuaj yeem tsim cov pob zeb zoo li lub raum?
Hematite (los yog haematite) Kuj tseem muaj ntau hom hematite, qee yam yog: raum ore, ib qho loj, botryoidal (lumpy) lossis reniform (lub raum zoo li tus) daim ntawv; specularite, micaceous (flaky) daim ntawv; oolitic, ib daim ntawv sedimentary tsim los ntawm cov nplej me me; liab ochre, ib daim ntawv liab earthy
