How does radioactive dating work
Radioactive dating of rock samples determines the age of rocks from the time it was formed.
Geologist determine the age of rocks using radioactive dating.
" Another way of explaining it is that when geologists talk about isotopes, they are talking about one element of differing masses.
All living things have carbon in them; but a small amount of that carbon is radioactive. The law of conservation and mass states that matter can not be destroyed nor created.But results can be gotten that are surprisingly accurate.As a "for instance" we might look at uranium-lead dating.A radioactive isotope is an isotope whose nucleus tends to release particles, radiant energy, or both; Radioactive dating is a technique for determining the age of material by measuring the amount of a particular radioactive isotope the material contain.Radioactive dating is carried out with substances which were formed at some unknown point in the past and contained a known proportion of a radioactive isotope of some element.
Carbon dating uses the carbon-14 isotope, with a half life of about 5700 years.
