The age of the earth zircon grains are important for uranium-thorium-lead dating because they contain abundant uranium and thorium parent isotopes. Geologist ralph harvey and historian mott greene explain the principles of radiometric dating and its application in determining the age of earth in this video segment from a science odyssey as the uranium in rocks decays, it emits subatomic particles and turns into lead at a constant rate.
