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.Thermoluminescence: It determines the period during which certain object was last subjected to heat.It is based on the concept that heated objects absorb light, and emit electrons. A Venn diagram depicts both dating methods as two individual sets.

Each original isotope, called the parent, gradually decays to form a new isotope, called the daughter.

Cross dating: This method compares the age of remains or fossils found in a layer with the ones found in other layers.

The comparison helps establish the relative age of these remains.

This Science Struck post enlists the differences between the absolute and relative dating methods.

Geological specimens that are unearthed need to be assigned an appropriate age.
