Superposition: superposition of rock units is a very simple and straightforward method of relative age determination the principle states that in a sequence of undeformed sedimentary rocks the oldest beds are at the bottom and the youngest ones are at the top. Explain and give examples of how physical fossil evidence can help in matching rock layers the law of superposition “relative” dating or time can be an. Geologists often need to know the age of material that they find they use absolute dating methods, sometimes called numerical dating, to give rocks an actual date, or date range, in number of years this is different to relative dating, which only puts geological events in time order most absolute.
