29

benefits and drawbacks of relative dating

relative dating uses visual observation but does not give an exact date

30

benefits and drawbacks of absolute dating

entails laboratory analysis of rock samples that will take a longer time. further, the dating results will still have to be cross-checked with mapping data.
