The correct distinction between relative dating and carbon dating is:
Relative dating is used in rock formations and fossils while carbon dating is used in organisms.
Relative dating is a method used to determine the chronological order of geological events and the relative ages of rock layers and fossils, while carbon dating, a form of radiometric dating, is used primarily for determining the age of organic materials found in fossils and remains, usually dating back to about 50,000 years.
