Use the finished chart and graph to reply the questions beneath. In a collection of undisturbed layered rocks every successive layer above is youthful than the layer below it. Therefore, the oldest rocks are at the bottom of the sequence and the youngest are at the top.

Suppose you find a fossil at one place that can’t be dated using absolute strategies.

Correlation with them has helped geologists, corresponding to Professor James Crampton, date many New Zealand rocks, together with those containing dinosaurs.
