What is a relative dating method
Relative dating is a science which deals with the comparative study of events from the past.The absolute age of these events need not inevitably be known.In case of a difference in the fluorine content, they are considered to be from different eras. It is an in-depth analysis in all the possible ways, taking into account all the related complexities.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.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.Strata is the layered arrangement or soil or rocks which lie parallel, one above the other.
These hard tissues include the teeth and the bones.
Chronometric techniques include radiometric dating and radio-carbon dating, which both determine the age of materials through the decay of their radioactive elements; dendrochronology, which dates events and environmental conditions by studying tree growth rings; fluorine testing, which dates bones by calculating their fluorine content; pollen analysis, which identifies the number and type of pollen in a sample to place it in the correct historical period; and thermoluminescence, which dates ceramic materials by measuring their stored energy.
Scientists first developed absolute dating techniques at the end of the 19th century.
It is a perfect example of superposition (layers deposited one above the other) and lateral continuity (undisturbed and covering large distances).
This oldest relative dating technique in the branch of geology, as the name suggests, focuses mainly on the strata.
