Relative Dating vs. Absolute Dating: Know the Difference
By Shumaila Saeed || Updated on December 25, 2023
Relative Dating determines the sequence of events or objects, whereas Absolute Dating provides an exact age or date.
Key Differences
Relative Dating is a method used to determine the order of past events by comparing the age of one object to another. Absolute Dating, in contrast, provides a specific age or date for an object or event, often expressed in years.

In Relative Dating, scientists use techniques like stratigraphy and biostratigraphy to understand the sequence of events. Absolute Dating methods, such as radiometric dating, measure radioactive decay to ascertain an exact age.

Relative Dating does not provide actual numerical dates, it places events in order of occurrence. Absolute Dating, on the other hand, offers a precise age estimate, making it more specific than relative methods.

Relative Dating can suggest whether an object is older or younger than another, but it cannot pinpoint when the object was formed or used. Absolute Dating, through methods like carbon dating, can provide a calendar year or range for an object's creation or use.
