What is a relative dating method

This technique of relative dating mainly works on the principle of chemical changes taking place in the fossils.

When remains of living beings get buried into sediments and turn to fossils, the bacteria present in the soil breakdown the proteins and fats from the bones.

Before this, archaeologists and scientists relied on deductive dating methods, such as comparing rock strata formations in different regions.

Chronometric dating has advanced since the 1970s, allowing far more accurate dating of specimens.

It concentrates mainly on the placement of the strata as well as its chronological sequence.

The principle of superposition is the core principle used in this method.

In anthropology, the study of humans living in the prehistoric era is done by collecting the data of human fossils found during excavations or research.Chronometric dating, also known as chronometry or absolute dating, is any archaeological dating method that gives a result in calendar years before the present time.Archaeologists and scientists use absolute dating methods on samples ranging from prehistoric fossils to artifacts from relatively recent history.The principle of superposition states that the layer which lies at the bottom is older than the one on top of it.In stratigraphic relative dating, the succession of layers can be seen as the timeline of its formation or deposition.

Most of the nitrogen contained in these fossils gets depleted progressively.
