The most popular method of radio dating is radio carbon dating which is possible because of the presence of C-14, an unstable isotope of carbon.C-14 has a half life of 5730 years which means that only half of the original amount is left in the fossil after 5730 years while half of the remaining amount is left after another 5730 years.However, archeologists still require further information to find out the items that are oldest and those that are youngest in the order.It is left for absolute dating to come up with the precise age of an artifact.An age could be estimated by measuring the amount of carbon-14 present in the sample and comparing this against an internationally used reference standard.

The impact of the radiocarbon dating technique on modern man has made it one of the most significant discoveries of the 20th century.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.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 type of dating employs many dating techniques like atomic clocks, carbon dating, annual cycle methods, and trapped electron method.
