Absolute age dating
Two broad categories of classification methods are relative dating and absolute dating.Though using similar methods, these two techniques differ in certain ways that will be discussed in this article.Upper most layers are considered the youngest while the lowermost deposition is considered as oldest.• Relative dating does not tell the exact age, it can only compare items as younger and older.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.It is clear then that absolute dating is based upon physical and chemical properties of artifacts that provide a clue regarding the true age.
Dating is a technique used in archeology to ascertain the age of artifacts, fossils and other items considered to be valuable by archeologists.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.This gives away the true age of the fossil that contains C-14 that starts decaying after the death of the human being or animal. Absolute Dating • Dating techniques are used in archeology to ascertain the age of old artifacts and a broad classification of these methods bifurcates them in relative dating and absolute dating • Relative dating comes to a conclusion based upon the study of layer formation of rocks.As the name implies, relative dating can tell which of the two artifacts is older.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.We can then use radioactive age dating in order to date the ages of the surfaces (when the rocks first formed, i.e. We also have meteorites from asteroids and can date them, too.
