Describe the difference between absolute and numerical dating

The Law of Superposition, which states that older layers will be deeper in a site than more recent layers, was the summary outcome of 'relative dating' as observed in geology from the 17th century to the early 20th century.The regular order of occurrence of fossils in rock layers was discovered around 1800 by William Smith.For example, there is a concept of absolute poverty that is used in some countries to measure the economy.A threshold is set up and the households having total earnings falling below this threshold are marked as poor.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.

Absolute and relative are concepts that are used in life to know more about people, things, and ideas.

For example, if there is only one internet service provider in an area, the customers, not knowing the features and services of other ISP in other areas, remain content with what they are getting.

They cannot compare the features of service and hence have an absolute experience, not relative.
