Understanding Time and Rock Units in Geology
Geologists use three different units to help in their study of the history of the earth. Time units represent the continuous flow of time through geologic history, rock units represent the different lithologies found across the globe, and time-rock units represent all the rocks formed worldwide during a specific period of geologic time. This week we will examine these units and how they relate to each other.
