The advantage of relative dating compared to absolute dating is:
There is no limit to the age range of the fossils being dated.
Relative dating allows scientists to determine the order of events and the relative ages of rocks and fossils without needing to know their exact age. In contrast, absolute dating provides a specific age, but it often relies on specific methods that may not be applicable to all fossils or rock layers, especially those that are very old or lack suitable materials for radiometric dating.
