Relative or absolute dating

Relative dating and radiometric dating are used to determine age of fossils and geologic features, but with different methods.Relative dating uses observation of location within rock layers, while radiometric dating uses data from the decay of radioactive substances within an object.Relative dating simply says one is older than the other but no age is specified.Tools like radiometric dating allow some samples to be assigned a certain age to within some accuracy.A threshold is set up and the households having total earnings falling below this threshold are marked as poor.

The difference between absolute and relative stems from the choice of comparison.They cannot compare the features of service and hence have an absolute experience, not relative.Though, in a market, when buying a product, one gets a chance to compare the product with other similar products made by several companies and this helps in choosing one that is most suitable for his requirements.Radiometric dating, based on known rates of decay of radioactive isotopes in objects, allows a specific age of an object to be determined to some degree of accuracy.The circumstances of the object may allow one to say that one object is older than another without being able to assign a particular age to the objects.
