It is possible to tell the number of years ago a particular rock or archeological site had been formed. Dating is a technique used in archeology to ascertain the age of artifacts, fossils and other items considered to be valuable by archeologists.
It is clear then that absolute dating is based upon physical and chemical properties of artifacts that provide a clue regarding the true age.
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. Two broad categories of classification methods are relative dating and absolute dating. Artifacts found in a layer can be compared with other items found in layers of similar age and placed in order.

Relative vs Absolute Dating. This gives away the true age of the fossil that contains C that starts decaying after the death of the human being or animal. Relative dating makes use of the common sense principle that in a deposition of layers.
However, age of deposition does not mean the age of artifacts found in that layer.
It implies that relative dating cannot say conclusively about the true age of an artifact. Dendrochronology is another of the popular method of finding the exact age through growth and patterns of thick and thin ring formation in fossil trees. Though using similar methods, these two techniques differ in certain ways that will be discussed in this article.
