Define relative dating

In relative dating the exact age of the object is not known; the only thing which made clear using this is that which of the two artifacts is older.Relative dating is a less advanced technique as compared to absolute dating.As more and more layers are deposited, the older rock layers end up at the bottom and the newer ones toward the top. What is the difference between relative and absolute age?Relative age is the age of a rock layer (or the fossils it contains) compared to other layers.The layers on top could only be laid down on top of the bottom layer so must be younger.However the relative ages of rocks is more commonly determined by the presumed ages of the fossils found in the sedimentary layers.The relative dating is the technique in the Geology through which the age is determined with relation to the other objects.In other words, we can say that in relative dating the archaeologist determines that which of the two fossil or the artifacts are older.

You have to date the volcanic layer above and below the fossil layer.Relative dating is used commonly when looking at the relative order of geological events.What can complicate relative dating is when the strata is not the right way up!The age of the fossil will be an age range between the ages of the two volcanic layers. The diagram below shows a portion of the Geologic Time Scale. In the field of Geology, dating is an important term as it is a technique through which evaluation regarding the age and period about the fossil, remains, the archaeologists do valuables and artifacts.
