Difference between relative and absolute dating method
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.
This gives away the true age of the fossil that contains C that starts decaying after the death of the human being or animal.

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. C has a half life of years which means that only half of the original amount is left in the fossil after years while half of the remaining amount is left after another years.
It is possible to tell the number of years ago a particular rock or archeological site had been formed. 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, an unstable isotope of carbon. It implies that relative dating cannot say conclusively about the true age of an artifact.
As the name implies, relative dating can tell which of the two artifacts is older. However, age of deposition does not mean the age of artifacts found in that layer.
Upper most layers are considered the youngest while the lowermost deposition is considered as oldest. There are many methods employed by these scientists, interested in the difference between relative and absolute dating method, to get to know the age of items.
Though using similar methods, these two techniques differ in certain ways that will be discussed in this article.
Dating is a technique used in archeology to ascertain the age of artifacts, fossils and other items considered to be valuable by archeologists. Artifacts found in a layer can be compared with other items found in layers of similar age and placed in order. 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. 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.
