Question

What is meant by geological time scale how it helps in determing the age of fossils

Answer 1

The geologic time scale (GTS) is a system ofchronological dating that relates geological strata (stratigraphy) to time. It is used bygeologists, paleontologists, and other Earth scientists to describe the timing and relationships of events that have occurred during Earth's history. The table of geologic time spans, presented here, agree with thenomenclature, dates and standard color codes set forth by the International Commission on Stratigraphy (ICS).

Answer 2

A geologic age is a subdivision of geologic time that divides an epoch into smaller parts. A succession of rock strata laid down in a single age on the geologic timescale is a stage.
