Learn how the amount of radioactive emissions given off by certain isotopes as they decompose can help determine the age of fossils. The decomposition rate of Carbon is more useful for dating young fossils and the decomposition rate of Uranium is more useful for dating older fossils.

The age of the Earth is ± billion years ( × 10 9 years ± 1%). This age may represent the age of the Earth's accretion, of core formation, or of the material from which the Earth formed. This dating is based on evidence from radiometric age-dating of meteorite material and is consistent with the radiometric ages of the oldest-known terrestrial and lunar samples.
