Dating methods

1. Relative dating is the dating of rocks but not by years.
2. Radiometric is used for old rocks.
3. Radiocarbon is for young rocks.
4. Cut out a core sample, count the rings for the age, and look at the wideness of the rings to see if it experienced dry or wet seasons.
5. A half-life is the amount of time necessary for one half of the nuclei in a sample to decay to its stable isotope.
