Which method for determining the age of artifacts measures the rate of decay in atoms in volcanic rock?
The method used for determining the age of artifacts by measuring the rate of decay in atoms in volcanic rock is radiometric dating, specifically the potassium-argon dating technique. This method relies on the radioactive decay of potassium isotopes into argon isotopes in volcanic rock to determine its age. By measuring the ratio of potassium to argon isotopes, scientists can calculate the age of the rock and any artifacts contained within it.
