Formula for radioactive carbon dating

Uranium is not the only isotope that can be used to date rocks; we do see additional methods of radiometric dating based on the decay of different isotopes.For example, with potassium-argon dating, we can tell the age of materials that contain potassium because we know that potassium-40 decays into argon-40 with a half-life of 1.3 billion years.For example, how do we know that the Iceman, whose frozen body was chipped out of glacial ice in 1991, is 5,300 years old?Well, we know this because samples of his bones and hair and even his grass boots and leather belongings were subjected to radiocarbon dating.For example, uranium-lead dating can be used to find the age of a uranium-containing mineral.

So, radiocarbon dating can be used to find the age of things that were once alive, like the Iceman.

However, rocks and other objects in nature do not give off such obvious clues about how long they have been around.
