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 helps determine what came first and what followed, but doesn't help determine actual age.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.They use absolute dating methods, sometimes called numerical dating, to give rocks an actual date, or date range, in number of years.This is different to relative dating, which only puts geological events in time Most absolute dates for rocks are obtained with radiometric methods.
