Question

How does the geologic time scale further our understanding about the biodiversity on our planet

Answer 1

Understanding Geologic Time
Introduction

Geologists at the American Museum of Natural History study rock layers and the plant and animal fossils found in them. They use radiometric dating to help establish the age of rocks. In doing so, they also establish the age of the fossils found in rocks. From the evidence they gather, geologists can piece together the physical history of the Earth.
