Long Answer: Sciences such as geology, paleontology and archeology are very interested in identifying the age of objects found and these scientists sometimes use either relative dating or absolute dating to characterize the age of the objects they study.Before radiometric dating it was difficult to determine the actual age of an object.Relative dating and radiometric dating are used to determine age of fossils and geologic features, but with different methods.Relative dating uses observation of location within rock layers, while radiometric dating uses data from the decay of radioactive substances within an object.Plus, get practice tests, quizzes, and personalized coaching to help you succeed.Free 5-day trial Learn how scientists determine the ages of rocks and fossils.

But really, how do scientists figure out how old their dinosaur bones are?

Radiometric dating, based on known rates of decay of radioactive isotopes in objects, allows a specific age of an object to be determined to some degree of accuracy.

Absolute dating is the process of determining an age on a specified chronology in archaeology and geology.

Relative dating helps determine what came first and what followed, but doesn't help determine actual age.

Radiometric dating, or numeric dating, determines an actual or approximate age of an object by studying the rate of decay of radioactive isotopes, such as uranium, potassium, rubidium and carbon-14 within that object. This rate provides scientists with an accurate measurement system to determine age.
