Numerical and relative dating
Relative dating uses observation of location within rock layers, while radiometric dating uses data from the decay of radioactive substances within an object.Continue Reading Relative dating observes the placement of fossils and rock in layers known as strata.In radiometric dating, the radioactive minerals within the rocks are used to know about the age of the object or the sites.
In relative dating, mostly the common sense principles are applied, and it is told that which artifact or object is older than the other one.
Radiometric dating, or numeric dating, determines an actual or approximate age of an object by studying the rate of decay of radioactive isotopes, such as uranium, potassium, rubidium and carbon-14 within that object. This rate provides scientists with an accurate measurement system to determine age.
