Kev sib raug zoo ntawm biostratigraphy thiab kev sib tham yog dab tsi? Biostratigraphy ib txwm ua raws thiab yog siv los ntsuas qhov kev sib tham tiag tiag. Biostratigraphy tsuas yog siv rau ntawm qhov chaw uas cov khaubncaws sab nraud povtseg tau dhau los nrog cov txheej txheem radiometric nkaus xwb.

Puas yog biostratigraphy txheeb ze lossis kev sib tham tiag?

Biostratigraphy yog cov txheej txheem ntawm kev siv cov pob txha pob txha sib sau ua ke hauv cov pob zeb los txiav txim siab lawv hnub nyoog, ib daim ntawv ntawm txheeb ze sib tham.

Kev sib raug zoo ntawm tus txheeb ze thiab kev sib tham yog dab tsi?

Dab tsi yog qhov txawv ntawm cov txheeb ze thiab cov hnub nyoog tiag? Lub hnub nyoog txheeb ze yog hnub nyoog ntawm txheej pob zeb (los yog cov pob txha muaj) piv rau lwm cov txheej Nws tuaj yeem txiav txim siab los ntawm kev saib ntawm txoj haujlwm ntawm pob zeb txheej. Tsis muaj hnub nyoog yog lub hnub nyoog naj npawb ntawm txheej pob zeb lossis pob txha.

Dab tsi yog qhov txawv ntawm cov txheeb ze thiab cov pob txha pob txha?

Qhov txawv ntawm qhov tseeb thiab kev txheeb ze yog qhov kev sib tam yog ib txheej txheem los txiav txim seb muaj pes tsawg hnub nyoog ntawm pob zeb lossis pob txhawhereas tus txheeb ze sib tam yog txheej txheem uas txiav txim lub hnub nyoog txheeb ze.

Yuav ua li cas sib tham isotopes muaj feem cuam tshuam?

Radiometric dating Feem ntau cov hnub rau pob zeb tau txais nrog cov txheej txheem xov tooj cua. Cov no siv cov khoom siv hluav taws xob hauv cov pob zeb ua cov moos geological. Cov atoms ntawm qee cov tshuaj muaj cov ntaub ntawv sib txawv, hu ua isotopes. Cov no tawg dhau sijhawm hauv cov txheej txheem kws tshawb fawb hu xov tooj cua decay.
