Relative age and relative dating
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.
It implies that relative dating cannot say conclusively about the true age of an artifact.
For example, if an area used for trash has modern refuse in it such as CDs and computers, and the layer underneath has cans made of tin, then it is safe to say the layer of tin cans have a greater relative age than the layer with modern refuse.
However, this does not say anything about the absolute age of the layers.

There are many methods employed by these scientists, interested in the old, to get to know the age of items.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.Upper most layers are considered the youngest while the lowermost deposition is considered as oldest.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.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.Continue Reading Relative age comes up often in various fields, such as archeology.If archaeologists find a site with layers in it, they can make assumptions about the relative age based on the composition of materials in each layer.• 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.
