Xov tooj cua sib tham yog ib txoj kev siv rau hnub pob zeb thiab lwm yam khoom raws li qhov paub txog kev lwj ntawm radioactive isotopes . Nrog radiocarbon sib tham , peb pom tias carbon-14 lwj mus rau nitrogen-14 thiab muaj ib nrab-lub neej ntawm 5,730 xyoo.
Yog li ntawd, dab tsi lub ntsiab yog siv nyob rau hauv radioactive sib tam?
Uranium
Ib yam li ntawd, cov xov tooj cua twg isotope siv nyob rau hauv geological dating? Uranium-238
Ua kom pom qhov no, dab tsi isotopes feem ntau siv hauv xov tooj cua sib tham?
Early Primate Evolution: Isotopes Feem ntau siv rau Xov Xwm Sib Tham . uranium-238 thiab potassium-40.
Cov xov tooj cua sib tham siv tau li cas?
Xov tooj cua sib tham yog ib txoj kev sib tham pob zeb thiab minerals siv xov tooj cua isotopes. Txoj kev no yog pab tau rau igneous thiab metamorphic pob zeb, uas tsis tuaj yeem sau hnub tim los ntawm txoj kev sib raug zoo stratigraphic siv rau cov pob zeb sedimentary. Ntau tshaj 300 qhov tshwm sim tshwm sim isotopes paub.

Yuav ua li cas cov txheej txheem ntawm cell faib nyob rau hauv eukaryotes feem ntau zoo ib yam li cell faib nyob rau hauv prokaryotes?
Tsis zoo li eukaryotes, prokaryotes (uas suav nrog cov kab mob) tau txais ib hom kev faib cell hu ua binary fission. Hauv qee qhov, cov txheej txheem no zoo ib yam li mitosis; Nws yuav tsum tau rov ua dua ntawm cov cell chromosomes, cais ntawm cov theej DNA, thiab kev sib cais ntawm niam txiv cell cytoplasm
Yuav ua li cas resistors coj nyob rau hauv series thiab nyob rau hauv parallel?
Txhua tus resistor nyob rau hauv ib tug series Circuit Court muaj tib tus nqi ntawm tam sim no ntws los ntawm nws. Txhua tus resistor nyob rau hauv ib qho hluav taws xob sib txuas muaj tib qhov hluav taws xob tag nrho ntawm qhov siv rau nws. Qhov tam sim no ntws los ntawm txhua tus resistor nyob rau hauv ib qho kev sib txuas sib txuas sib txawv, nyob ntawm qhov tsis kam
Qhov twg hauv qab no yog lub ntsiab lus ntawm radiometric dating?
Radiometric dating nyob rau hauv American English noun. txhua txoj kev los txiav txim lub hnub nyoog ntawm lub ntiaj teb cov ntaub ntawv los yog cov khoom ntawm cov organic keeb kwm raws li kev ntsuas ntawm ib tug luv luv-lived radioactive ntsiab los yog tus nqi ntawm ib tug ntev-nyob radioactive caij ntxiv rau nws cov khoom lwj
Yuav ua li cas koj xam radiometric dating?
Radioactive Dating. log F = (N/H)log(1/2) qhov twg: F = feem seem N = pes tsawg xyoo thiab H = ib nrab neej. Txhawm rau txiav txim siab qhov seem tseem tshuav, peb yuav tsum paub ob qho tib si tam sim no thiab cov nyiaj tam sim no thaum cov pob zeb tsim
Yuav ua li cas yog ib co qauv nyob rau hauv landforms nyob rau hauv lub ntiaj teb no?
Cov txheej txheem ntawm lub cev no ua rau cov roob, tiaj, toj, thiab toj siab, plaub hom av loj. Phaj tectonics tuaj yeem tsim cov roob thiab toj roob hauv pes thaum yaig tuaj yeem hnav cov av los tsim cov hav thiab hav zoov
