Relative dating is used to arrange geological events and the rocks are left behind the sequence. Stratigraphy is the method of reading the order.
Explanation:
The Relative dating do not provide actual numerical dates for the rocks. The principle states that in an undisturbed sequence of sediments layers are increased in age from the top to bottom.
The difference between relative and absolute dating is the relative age is age of a rock layer when compared to other layer and Absolute age is the numeric age of layer of rocks or fossils and it is determined by using radiometric dating.
The relative dating techniques are used for climate chronology, dendrochronology, ice core sampling, stratigraphy, and seriation.
