The popular age of 4.6 billion years old for the planet earth was derived by applying radiometric dating techniques to a meteorite called "allende" (a-yen-day), which scientists assume formed at the same time as the earth. To learn more about these foundational assumptions, explore our radiometric dating site. Students not only want to know how old a fossil is, but they want to know how that age was determined.

The unstable element will eventually decay into a stable element.Scientists measure the proportion of carbon-14 left in the organism to determine its age. Can we determine the age of the earth, and if so, how?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.
