However, rocks and other objects in nature do not give off such obvious clues about how long they have been around.So, we rely on radiometric dating to calculate their ages.Radiometric dating is used to estimate the age of rocks and other objects based on the fixed decay rate of radioactive isotopes.

So, we have a “clock” which starts ticking the moment something dies.

Obviously, this works only for things which were once living.

C at all if they really were over a billion years old, yet the radiocarbon lab reported that there was over 10 times the detection limit.

Thus they had a radiocarbon ‘age’ far less than a million years!

) is only 5,730 years—that is, every 5,730 years, half of it decays away.

After two half lives, a quarter is left; after three half lives, only an eighth; after 10 half lives, less than a thousandth is left.Recall that atoms are the basic building blocks of matter.Atoms are made up of much smaller particles called protons, neutrons, and electrons.Scientists use a technique called radiometric dating to estimate the ages of rocks, fossils, and the earth.Many people have been led to believe that radiometric dating methods have proved the earth to be billions of years old.Thus they probably formed at a depth of 100–200 km.
