What is the advantage of relative dating

These processes result in All of these processes confuse the stratigraphic record.In many cases, however, it is possible to reconstruct the original sequence of strata so that they can be used for relative dating.It only sequences the age of things or determines if something is older or younger than other things.

This is due to the fact that one or both of the objects may have been moved or redeposited into a different location.Relative dating is the science of determining the relative order of past events (i.e., the age of an object in comparison to another), without necessarily determining their absolute age, (i.e. In geology, rock or superficial deposits, fossils and lithologies can be used to correlate one stratigraphic column with another.Prior to the discovery of radiometric dating which provided a means of absolute dating in the early 20th century, archaeologists and geologists used this technique to determine ages of materials.Ice cores showed the age of a military plane buried in the artic as thousands of years old.Similarly, dendrochronology measures the tree rings in trees and assumes they represent years.
