The relative dating techniques are very effective when it comes to radioactive isotope or radiocarbon dating.However, not all fossils or remains contain such elements.Absolute dating, also called numerical dating, arranges the historical remains in order of their ages.Whereas, relative dating arranges them in the geological order of their formation.Relative techniques are of great help in such types of sediments.➤ It determines if an object/event is younger or older than another object/event from history.➤ Relative dating is qualitative.➤ This technique helps determine the relative age of the remains.➤ It is less specific than absolute dating.➤ Relative dating is comparatively less expensive and time-efficient.➤ It works best for sedimentary rocks having layered arrangement of sediments.The following are the major methods of relative dating.The area of intersection of both sets depicts the functions common to both.Take a look at the diagram to understand their common functions.
The rate of decay of these elements helps determine their age, and in turn the age of the rocks.
The two approaches are often complementary, as when a sequence of occurrences in one context can be correlated with an absolute chronlogy elsewhere.
Local relationships on a single outcrop or archaeological site can often be interpreted to deduce the sequence in which the materials were assembled.
When we observe the intersection in this diagram depicting these two dating techniques, we can conclude that they both have two things in common:1.
Provide an idea of the sequence in which events have occurred.2.
