Use the completed chart and graph to reply the questions beneath. In a collection of undisturbed layered rocks every successive layer above is youthful than the layer beneath it. Therefore, the oldest rocks are at the backside of the sequence and the youngest are on the prime. This useful resource is explicitly designed to construct in the course of this disciplinary core idea.
Suppose you discover a fossil at one place that cannot be dated utilizing absolute methods. That fossil species may 
have been dated some place else, so you’ll find a way to match them and say that your fossil has a similar age. Some of the most helpful fossils for dating functions are very small ones. For instance, microscopic dinoflagellates have been studied and dated in nice element around the world. Correlation with them has helped geologists, corresponding to Professor James Crampton, date many New Zealand rocks, together with those containing dinosaurs.
