Relative dating or absolute dating
Absolute dating is the process of determining an age on a specified chronology in archaeology and geology some scientists prefer the terms chronometric or calendar dating, as use of the word absolute implies an unwarranted certainty of accuracy absolute dating provides a numerical age or range in contrast with relative.

In this activity, you will be able to combine your knowledge of relative dating methods (learned in activity 7) with the absolute dating method to determine more. Subsequently, radiocarbon dating, an absolute dating technique, was used to date the bones directly and provided a date of. Before more precise absolute dating tools were possible, researchers used a variety of comparative approaches called relative dating.
Although both relative and absolute dating methods are used to estimate the age of historical remains, the results produced by both these techniques for the. Relative dating is the science of determining the relative order of past events without necessarily determining their absolute age, (ie estimated age) in geology. 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.
