Cov kauj ruam hauv kev txheeb xyuas:
- Txiav txim siab xim (qhia tau hais tias muaj pes tsawg leeg ntxhia)
- Txiav txim siab qhov kev ntxhib los mos (qhia txog keeb kwm txias)
- Phaneritic = cov nplej loj.
- Aphanitic = me nplej (me me dhau mus txheeb xyuas nrog rau qhov muag)
- Porphyritic = cov nplej zoo sib xyaw nrog cov nplej loj.
- Vesicular = qhov.
- Glassy = iav zoo li.
Tsis tas li cov lus nug yog, koj tuaj yeem qhia koj li cas pob zeb uas koj muaj?
Muaj peb yam tseem ceeb ntawm pob zeb , uas yog txhais los ntawm yuav ua li cas lub pob zeb yog tsim. Sedimentary pob zeb feem ntau pom nyob rau hauv txheej. Ib txoj kev mus qhia yog tias a pob zeb qauv yog sedimentary yog saib yog itis ua los ntawm cov nplej. Qee cov qauv ntawm sedimentary pob zeb xws li limestone, sandstone, thee thiab shale.
Tsis tas li ntawd, koj tuaj yeem qhia qhov txawv ntawm sedimentary thiab igneous pob zeb? Paub qhov qhov sib txawv ntawm peb loj pob zeb hom. Igneous pob zeb yog tsim los ntawm orslowcooling ceev ntawm magma/lava. Metamorphic pob zeb hloov formbased ntawm qhov kub, siab, lossis chemicalactivity. Sedimentary pob zeb yog tsim los ntawm piecesofsmaller pob zeb , fossils, thiab sediments.
Ua kom pom qhov no, qhov kev ntxhib los mos ntawm cov pob zeb tsis zoo yog dab tsi?
Muaj cuaj hom tseem ceeb ntawm igneousrocktextures : Phaneritic, vesicular, aphanitic, porphyritic, poikilitic, glassy, pyroclastic, equigranular, andspinifex. Txhua yam ntawm kev ntxhib los mos muaj ntau yam sib txawv uas ua rau lawv txawv.
Koj yuav faib ib lub pob zeb li cas?
Classifying Pob Zeb . Pob zeb yog cais raws li Igneous, Sedimentary, lossis Metamorphic. Igneous pob zeb yog tsim los ntawm volcanic kev ua si. Lawv yog cais ntxiv los ntawm lawv cov keeb kwm, kev ntxhib los mos, thiab mineralcomposition.

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
Kuv yuav txheeb xyuas lub pob zeb li cas?
Cov Lus Qhia Pob Zeb Igneous pob zeb xws li granite los yog lava yog tawv, khov yaj nrog me ntsis kev ntxhib los mos los yog txheej. Cov pob zeb zoo li no muaj feem ntau cov xim dub, dawb thiab / lossis grey minerals. Sedimentary pob zeb xws li limestone los yog shale yog hardened sediment nrog xuab zeb los yog av nplaum-zoo li txheej (strata)
Yuav ua li cas koj qhia yog hais tias lub pob zeb yog igneous metamorphic los yog sedimentary?
Tshawb xyuas koj lub pob zeb kom pom cov cim pom pom. Igneous pob zeb yog tuab heev thiab nyuaj. Cov pob zeb metamorphic kuj tseem tuaj yeem muaj lub ntsej muag iav. Sedimentary pob zeb uas tsis muaj nplej yuav zoo li cov av nkos qhuav. Cov pob zeb sedimentary uas tsis muaj nplej kuj zoo li mos, asthey feem ntau tuaj yeem khawb tau yooj yim nrog tus ntiv tes
Lub npe rau lub pob zeb nruab nrab ntawm cov pob zeb uas txias heev yog dab tsi?
Extrusive igneous pob zeb
Cov pob txha pob txha tau siv li cas los txhais thiab txheeb xyuas qhov kev faib tawm ntawm lub sijhawm geology?
Index fossils yog siv nyob rau hauv lub formal architecture ntawm geologic lub sij hawm rau txhais lub hnub nyoog, epochs, lub sij hawm, thiab eras ntawm lub sij hawm geological. Cov pov thawj rau cov xwm txheej no tau pom nyob rau hauv cov ntaub ntawv fossil nyob qhov twg muaj qhov ploj ntawm pawg loj ntawm cov tsiaj hauv ib lub sijhawm luv luv ntawm geologically
