Radiocarbon dating definition for kids
For Carbon dating we have already experimentally measured the amount.
Isotopes are important to geologists because each radioactive element decays at a constant rate, which is unique to that element.

For example, fission track dating measures the microscopic marks left in crystals by subatomic particles from decaying isotopes.Another example is luminescence dating, which measures the energy from radioactive decay that is trapped inside nearby crystals.Geologists often need to know the age of material that they find.
They use absolute dating methods, sometimes called numerical dating, to give rocks an actual date, or date range, in number of years.
The technique used is called carbon dating, and in this lesson we will learn what this is and how it is used.
Relative dating and radiometric dating are used to determine age of fossils and geologic.
Each original isotope, called the parent, gradually decays to form a new isotope, called the daughter.
Each isotope is identified with what is called a ‘mass number’.
For example, the decay of potassium-40 to argon-40 is used to date rocks older than 20,000 years, and the decay of uranium-238 to lead-206 is used for rocks older than 1 million years.
