Definition of relative dating of fossils
In other words, we can say that the age in relative dating is ascertained by witnessing the layers of deposition or the rocks.
As the word relative tells that defining the object with respect to the other object, it will be pertinent to mention here that actual numerical dates of the rocks or sites are not known in this type of dating.
The absolute dating is also sometimes referred to as the relative numerical dating as it comes with the exact age of the object.
The absolute dating is more reliable than the relative dating, which merely puts the different events in the time order and explains one using the other.
The base layer must come first, then the second and then the third.
So I can say the second layer is younger than the first and older than the third but I have no idea whether the cake is 5 minutes or 5 million years old.
Sometimes beds of rock can turn over the other way, so be very cautious when relatively dating rocks!
Relative Dating and Absolute Dating are two types of such techniques which are under practice to determine the age of the fossils, objects or civilizations.
This feature is produced by changes in deposition over time.
With this in mind geologist have long known that the deeper a sedimentary rock layer is the older it is, but how old?
We can absolute date materials but it will always have an uncertainty range, we can never know the age with infinite precision.
Relative dating is like looking at a multi-layered cake.
