Relative dating techniques in archaeology
The annual rings vary in size, depending on the weather conditions in each region, but they are similar for all trees of the same area.
If the sequence of rings is know for a certain area it is possible to fit in all new woods found and to date them very precisely.
Inscribed objects sometimes bear an explicit date, or preserve the name of a dated individual. However, only a small number of objects are datable by inscriptions, and there are many specific problems with Egyptian chronology, so that even inscribed objects are rarely datable in absolute terms.Absolute dating provides a numerical age for the material tested, while relative dating can only provide a sequence of age.One of the most widely used and well-known absolute dating techniques is carbon-14 (or radiocarbon) dating, which is used to date organic remains.Absolute dates do not necessarily tell us when a particular cultural event happened, but when taken as part of the overall archaeological record they are invaluable in constructing a more specific sequence of events.Absolute dating contrasts with the relative dating techniques employed, such as stratigraphy.
