Question: What is radiometric dating in simple words?

Radiometric dating, often called radioactive dating, is a technique used to determine the age of materials such as rocks. It is based on a comparison between the observed abundance of a naturally occurring radioactive isotope and its decay products, using known decay rates.Radiometric dating, often called radioactive dating, is a technique used to determine the age of materials such as rocks.

How is radiometric dating?

Potassium-argon dating is a method that allows us to calculate the age of a rock, or how long ago it was formed, by measuring the ratio of radioactive argon to radioactive potassium within it. Radioactive potassium (40K – a solid) decays to radioactive argon (40Ar – a gas), at a known rate.
