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.If any of these three conditions is not accurately known, the hourglass will give an inaccurate measure of time.Radiometric dating is based on the fact that radioactive isotopes decay to form isotopes of different elements.If certain things are known, it is possible to calculate the amount of time since the parent isotope began to decay.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.There is also a difference in the timescale used to explain the layers.

Creationists do not necessarily disagree with this concept, but it can only be applied to layers that are found in one location and/or can be determined to have been deposited in a continuous layer over a very wide area.

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.

The dates must be inferred based on assumptions about the ratios.

A fear of God and reverence for His Word is the beginning of wisdom.

Starting with the Bible and developing a model for dating events in earth history will lead us to the truth.

Far from being data, these dates are actually interpretations of the data.
