Dating is a technique used in archeology to ascertain the age of artifacts, fossils and other items considered to be valuable by archeologists.
Two broad categories of classification methods are relative dating and absolute dating.
Though using similar methods, these two techniques differ in certain ways that will be discussed in this article.
As the name implies, relative dating can tell which of the two artifacts is older.
This is a method that does not find the age in years but is an effective technique to compare the ages of two or more artifacts, rocks or even sites.
It implies that relative dating cannot say conclusively about the true age of an artifact.
Absolute dating, on the other hand is capable of telling the exact age of an item using carbon dating and many other techniques that were not there in earlier times.
Relative dating makes use of the common sense principle that in a deposition of layers.A layer that is higher is of later age than a layer that is lower in order.This means that the oldest are the strata that are lying at the bottom.However, age of deposition does not mean the age of artifacts found in that layer.Artifacts found in a layer can be compared with other items found in layers of similar age and placed in order.However, archeologists still require further information to find out the items that are oldest and those that are youngest in the order.
