Question

What is the purpose of a geological time scale ?

Answer 1

The correct answer is C. It is used to determine the absolute dates in years for different periods.

Explanation

The geological timescale is a tool that has been developed over the years by geologists to establish a frame of reference in which important events in the history of the Earth and life are represented in chronological order. This scale is organized from divisions and subdivisions, from the relative age of the rocks according to their relative age and the absolute time elapsed since the formation of the Earth to the present. Through this scale it has been possible to establish historical periods such as when dinosaurs lived. So the correct answer is C.
