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.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.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.It is clear then that absolute dating is based upon physical and chemical properties of artifacts that provide a clue regarding the true age.

Historians can tell what cultures thrived in different regions and when they disintegrated.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.Archaeology has undoubtedly enriched mankind’s history like no other science.There is a greater part of man’s unwritten past that archaeology has managed to unravel.
