radiocarbon dating is a method that provides objective age estimates for carbonbased materials that originated from living organisms an age could be estimated by measuring the amount of carbon14 present in the sample and comparing this against an internationally used reference standard.

relative dating is the science of determining the relative order of past events ie the age of an object in comparison to another without necessarily determining their absolute age ie estimated agein geology rock or superficial deposits fossils and lithologies can be used to correlate one stratigraphic column with another prior to the discovery of radiometric dating.
Before more precise absolute dating tools were possible researchers used a variety of comparative approaches called relative dating these methods some of which are still used today provide only an approximate spot within a previously established sequence think of it as ordering rather than dating.
The real heart of the ageoftheearth debate if debate is the right word is always radiometric dating there are lots of ways to guesstimate ages and geologists knew the earth was old a long time ago and i might add that they were mostly christian creationist geologists but they didnt know how oldradiometric dating actually allows the measurement of absolute.
How radiometric dating works in general radioactive elements decay gradually into other elements the original element is called the parent and the result of the decay process is called the daughter element.
44 the test methods described here directly discriminate between product carbon resulting from contemporary carbon input and that derived from fossilbased input a measurement of a products 14 c 12 c or 14 c 13 c content is determined relative to a carbon based modern reference material accepted by the radiocarbon dating.
Chemical bonds molecular compounds are held together on an atomic level by chemical bonds three types of chemical bonds include ionic bonds metallic bonds and covalent bondsthe types of chemical bond influence the physical properties of the molecular compounds they form.
the isochron method many radioactive dating methods are based on minute additions of daughter products to a rock or mineral in which a considerable amount of daughtertype isotopes already exists.
