Fossils ntawm extinct cov kab mob yuav nyob ze ntawm BOTTOM ntawm lub geological kab vim hais tias yog qhov uas cov pob zeb qub tshaj plaws.
Kuj paub, yuav ua li cas cov kws tshawb fawb siv kab ke geology los txiav txim siab txog lub hnub nyoog pob zeb?
Cov kws tshawb fawb tuaj yeem siv cov kab geology kwv yees cov muaj hnub nyoog ntawm pob zeb txheej . Cov kws tshawb fawb piv a txheej ntawm pob zeb nrog zoo ib yam txheej hauv a geological kab . Cov txheej lawv piv tej zaum yuav nyob rau hauv tib txoj hauj lwm txheeb ze rau lwm cov txheej txheem. Tej zaum lawv yuav muaj tib cov pob txha.
Kuj Paub, cov fossils nyob qhov twg? Fossils feem ntau yog pom qhov twg cov pob zeb sedimentary ntawm lub hnub nyoog raug raug nthuav tawm, xws li cov hav dej, pob tsuas thiab toj roob hauv pes, thiab kev nthuav tawm tib neeg xws li quarries thiab txoj kev txiav.
Kuj tseem yuav paub, geologists siv cov kab ke geology li cas?
Cov geological kab yog lub theoretical classification system rau cov txheej ntawm pob zeb thiab pob txha pob txha uas ua rau lub ntiaj teb crust (tseem hu ua tus qauv. geological kab ). Geologists tau cuam tshuam cov txheej ntawm pob zeb nrog cov txheej txheem ntawm cov xwm txheej xav tias tau tshwm sim ntau pua lab xyoo.
Hom pob zeb twg yog fossils pom nyob rau hauv?
sedimentary pob zeb
Pom zoo:
Nws puas yuav ua rau pom qhov sib npaug ntawm kab sib npaug mus rau ib kab thiab los ntawm ib qho taw tes ntawm kab?
Qhov sib npaug ntawm ib kab uas yog parallel lossis perpendicular rau ib kab? Cov lus teb tau: Cov nqes hav ntawm cov kab sib npaug sib npaug. Hloov txoj kab nqes paub thiab cov kev sib koom ua ke ntawm ib qho taw tes ntawm lwm txoj kab rau hauv daim ntawv point-slope kom pom qhov sib npaug ntawm kab sib npaug
Puas muaj cov pob txha pom nyob hauv cov pob zeb sedimentary?
Ntawm peb hom pob zeb loj, fossils feem ntau pom muaj nyob hauv pob zeb sedimentary. Tsis zoo li feem ntau cov pob zeb igneous thiab metamorphic, cov pob zeb sedimentary tsim ntawm qhov kub thiab txias uas tsis rhuav tshem cov pob txha
Koj yuav pom phospholipids nyob qhov twg hauv cov kab mob ntawm tes?
Sab nrauv ntawm cov kab mob Gram-tsis zoo, qhov sib piv, muaj kev sib koom ua ke ntawm phospholipids: feem ntau ntawm cov phospholipids nyob rau hauv cov nplooj ntawv sab hauv ntawm daim nyias nyias, thaum cov nplooj ntawv sab nrauv muaj qee cov phospholipids, tab sis kuj muaj cov proteins thiab hloov lipid molecules hu ua lipopolysaccharides ( LPS)
Cov pob txha pob txha qhia peb li cas?
Cov pob txha pob txha muab peb cov pov thawj tsis ncaj ntawm lub neej yav dhau los, xws li cov hneev taw, lem, burrows, tho txawv, thiab cov quav tso tseg los ntawm cov tsiaj, tsis yog qhov seem ntawm lub cev ntawm tus tsiaj tiag tiag
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
