Describe the difference between relative dating and absolute dating. describe how the two methods were used together to develop the geologic time scale.

Relative dating is used to identify what things existed before or after another. This is usually seen in fossils in which layers of new fossils are laid on top of each other.

Filling in the gaps of absolute dating with that of relative dating, these methods made the geologic time scale.
