Ga=billion years ago, Ma=million years ago. Geologic time has been subdivided into a series of divisions by geologists. Eon is the largest division of time, followed by era, period, epoch, and age.Quick Answer. Scientists use two approaches to date rocks and fossils. Relative age dating is used to determine whether one rock layer (or the fossils in it) are older or younger than another base on their relative position: younger rocks are positioned on top of older rocks. Absolute age dating (or, radiometric dating) determines the age of a ...The time interval occupied by the geological history of the earth is known as the Geologic time.
