Cov pob zeb zoo li no muab cov xwm txheej zoo tshaj plaws rau pob txha pob txha vim tias cov nroj tsuag thiab tsiaj txhu tuaj yeem npog los ntawm cov txheej txheem ntawm cov ntaub ntawv dhau sijhawm, yam tsis muaj kev puas tsuaj.
Ib yam li ntawd, tib neeg nug, vim li cas cov pob txha muaj nyob hauv pob zeb sedimentary?
Sedimentary pob zeb tuaj yeem muaj pob txha vim, tsis zoo li feem ntau igneousand metamorphic pob zeb , lawv tsim ntawm qhov kub thiab txias uas tsis ua kom puas pob txha seem. Cov kab mob tuag tuaj yeem dhau los ua sediments uas yuav, raws li txoj cai, dhau los sedimentary pob zeb.
Ib tug kuj yuav nug, koj qhia li cas yog lub pob zeb muaj pob txha? Nws kuj yog ib lub tswv yim zoo los nrhiav kos npe tias cov pob zeb muaj ib tug fossil ua ntej sim ua txhaum nws, ib feem ntawm a pob txha tej zaum yuav pom ntawm qhov chaw pob zeb . Koj ua tau txheeb xyuas lub limestone los ntawm nws yog lighter grey xim thiab hardness, nws yuav tsum yog heev nyuaj rau tawg yam tsis muaj rauj.
Kuj nug, vim li cas nws tsis tshua pom cov pob txha hauv cov pob zeb metamorphic?
Igneous pob zeb daim ntawv los ntawm molten pob zeb , thiab tsis tshua muaj pob txha hauv lawv. Metamorphic pob zeb tau muab tso rau hauv siab heev, rhuab, squashed los yog stretched, thiab pob txha feem ntau tsis muaj sia nyob cov mob hnyav no. Feem ntau nws tsuas yog sedimentary pob zeb uas muaj pob txha.
Vim li cas cov pob txha muaj feem ntau pom muaj nyob hauv qee hom pob zeb thiab tsis yog lwm tus?
Fossils yog ntau dua hauv qee yam ntawm sedimentary pob zeb tshaj lwm tus . Muaj ntau ntau yam uas tuaj yeem ua rau muaj qhov tshwm sim ntawm lub cev raug khaws cia raws li ib pob txha . Fossils yog feem ntau nyob rau hauv limestones. Qhov ntawd yog vim feem ntau limestones muaj ib feem los yog feem ntau ntawm lub plhaub ntawm cov kab mob.

Feem ntau hom pob zeb tsis ua haujlwm zoo hauv pob zeb tumbler. Yog tias koj sib tov zoo tumbling ntxhib nrog pob zeb uas qis dua qib qis, cov khoom, cov npoo ntse thiab tawg ntawm cov khoom hauv qab-tumbling-qib tej zaum yuav ua rau cov polish ntawm txhua lub pob zeb hauv lub thoob
Vim li cas qee qhov extrusive igneous pob zeb pom nyob hauv av?
Cov ntsiab lus. Intrusive igneous pob zeb txias los ntawm magma maj mam vim hais tias lawv faus rau hauv qab saum npoo, yog li lawv muaj cov muaju loj. Extrusive igneous pob zeb txias los ntawm lava sai heev vim lawv tsim ntawm qhov chaw, yog li lawv muaj cov muaju me me
Hom pob zeb twg yog amethyst pom nyob rau hauv?
Metamorphic. Txawm hais tias feem ntau cov pob zeb amethyst muaj nyob rau hauv cov pob zeb tsis zoo, Lub Quartz Page hais tias amethysts kuj pom muaj nyob hauv cov pob zeb metamorphic. Lawv tsis tshua pom muaj nyob rau hauv cov pob zeb sedimentary, vim hais tias cov tshuaj lom neeg tsim nyog rau kev tsim amethyst feem ntau tsis pom zoo li cov pob zeb sedimentary
Hom pob zeb twg ua rau feem ntau ntawm lub ntiaj teb crust thiab vim li cas?
Cov pob zeb ntau tshaj plaws nyob rau hauv lub crust yog igneous, uas yog tsim los ntawm qhov txias ntawm magma. Lub ntiaj teb crust yog nplua nuj nyob rau hauv igneous pob zeb xws li granite thiab basalt. Cov pob zeb metamorphic tau hloov pauv ntau heev vim yog cua sov thiab siab
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
