Question

What is meant by geological time scale? Why is it necewsqry to determine the age of fossils

Answer 1

The geologic time scale (GTS) is a system of chronological dating that relates geological strata (stratigraphy) to time. It is used by geologists, paleontologists, and other Earth scientists to describe the timing and relationships of events that have occurred during Earth's history.The principle states that any geologicfeatures that cut across strata must have formed after the rocks they cut through . In this case, fossils can be useful tools for understanding the relative ages of rocks. Each fossil species reflects a unique period of time in Earth's history
