How is absolute dating used to evaluate geologic time
Some of the common isotope pairs used are K-Ar, Rb-Sr, Pb-Pb, and U-Pb.
Carbon-14 dating is another common technique, but it can only be used on carbon-containing things that were once alive.
It is possible to measure the ratio of the different radioactive parent isotopes and their daughter isotopes in a rock, but the ratios are not dates or ages.
For example, if you began with 1 gram of carbon-14, after 5,730 years you would be left with 0.50 g and only 0.25 g after 11,460 years.Recent research by a team of creation scientists known as the RATE (arth) group has demonstrated the unreliability of radiometric dating techniques.Even the use of isochron dating, which is supposed to eliminate some initial condition assumptions, produces dates that are not reliable.The Bible gives us a much more reliable history of the earth as it was recorded by God.
When someone mentions scientific dating methods, the first thing to come to mind for most people is carbon dating.
The method of calculating radiometric dates is like using an hourglass.
