Which dating method provides a relative age?
Natural EnvironmentsThe abundances of parent and daughter isotopes in a sample can be measured and used to determine their age. This method is known as radiometric dating. What are relative dating methods? In relative dating, we determine which things are older or younger based on their relationships. For example, we know from geology that soil layers
