Radiocarbon dating - Wikipedia

Radioactive dating is a process used to determine the age of an object by measuring the amount of given radioactive material it contains. This process is usually used to determine the age of Rocks or Carbon. It is the principle source of information about the absolute age of rocks and other geological features including the age of earth itself.
