Radiometric dating
Explanation: Radiometric dating is a precise method of determining the age of archeological artifacts and rocks, it usually makes use of certain radio isotopes of Uranium-235,Rubidiun-87 etc.
Radiometric dating which is also known as radioactive dating is carried out by comparing the naturally occurring radioactive materials of the artifact or rock under study to product of its decay process.
Craters dating is a random process so its reliability can not be guaranteed.
