It is possible to tell the number of years ago a particular rock or archeological site had been formed.Two broad categories of classification methods are relative dating and absolute dating.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 possible because properties of rock formations are closely associated with the age of the artifacts found trapped within them.This type of dating employs many dating techniques like atomic clocks, carbon dating, annual cycle methods, and trapped electron method.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.As the word relative tells that defining the object with respect to the other object, it will be pertinent to mention here that actual numerical dates of the rocks or sites are not known in this type of dating.
In other words, we can say that the age in the relative dating is ascertained by witnessing the layers of deposition or the rocks.
The relative dating is the technique to ascertain the age of the artifacts, rocks or even sites while comparing one from the other.
In relative dating the exact age of the object is not known; the only thing which made clear using this is that which of the two artifacts is older.
• Relative dating does not tell the exact age, it can only compare items as younger and older.
• Absolute dating techniques can tell the exact age of an artifact by employing various techniques, the most popular being C-14 dating.
