Introduction
Geologists generally know the age of a rock by determining the age of the group of rocks, or formation, that it is found in. The age of formations is marked on a geologic calendar known as the geologic time scale. Development of the geologic time scale and dating of formations and rocks relies upon two fundamentally different ways of telling time: relative and absolute.
Relative dating places events or rocks in their chronologic sequence or order of occurrence. It is a qualitative way of describing the sequence of events. The sequence orders the events but provides no information on the amount of time passed or between events. To determine the sequence of geologic events, several principles must be followed.
