Radiometric dating Definitions

  1. When scientists measure the ratio of different isotopes and calculate how many half-lives (in years) have passed since an organism was fossilized or a rock was formed is called radiometric dating.

  2. Radiometric dating is a dating technique based on the decay of radioactive isotopes.

Radiometric dating Explanation

Radiometric dating is a technique used to date materials such as rocks or carbon, in which trace radioactive impurities were selectively incorporated when they were formed. Basically radiometric dating is the process of dating rocks or carbon based on the traces of radioactive materials. For example, studying the decay rate or half life of certain elements present in the structure, the age of the rock or any fossil can be estimated. The method compares the abundance of a naturally occurring radioactive isotope within the material to the abundance of its decay products, which form at a known constant rate of decay. This type of dating is now the principal source of information about the absolute age of rocks and other geological features, including the age of fossilized life forms or the age of the Earth itself, and can also be used to date a wide range of natural and man-made materials.

Radiometric dating Explanation

Radiometric dating or radioisotope dating is a technique used to date materials such as rocks or carbon, in which trace radioactive impurities were selectively incorporated when they were formed. The method compares the abundance of a naturally occurring radioactive isotope within the material to the abundance of its decay products, which form at a known constant rate of decay which helps find its original age.
