More about how could radiometric dating be used to sort out the relative ages of rock layers:
The most widely known form of radiometric dating is carbon dating. This is what archaeologists use to determine the age of human-made artifacts. But carbon dating won't work on dinosaur bones. The half-life of carbon is only 5, years, so carbon dating is only effective on samples that are less than 50, years old. Dinosaur bones, on the other hand, are millions of years old -- some fossils are billions of years old. To determine the ages of these specimens, scientists need an isotope with a very long half-life. Some of the isotopes used for this purpose are uranium, uranium and potassium , each of which has a half-life of more than a million years. Unfortunately, these elements don't exist in dinosaur fossils themselves.

Why can't radioactive dating be used to date sedimentary rock? Would you like to merge this question into it? Would you like to make it the primary and merge this question into it? Merge this question into. Split and merge into it. Sedimentary rock is composed of the weathered remains of a variety of rocks of all ages. It would therefore only be possible to date specific components of a sample, none of which would equate to the age of the sedimentary rock as a unit.
