Radioactive dating of rocks


A process for determining the age of an object by measuring the amount of a given radioactive material it contains. If one knows how much of this radioactive material was present initially in the object (by determining how much of the material has decayed), and one knows the half-life of the material, one can deduce the age of the object.

Elements occur naturally in the earth, and they can tell us a lot about our Earth's past. Carbon, uranium and potassium are just a few examples of elements used in radioactive dating.
