The key difference between relative dating and radiometric dating is that the dating cannot provide actual numerical dates whereas the radiometric dating can provide actual numerical dates. Relative dating and radiometric dating are two types of parameters that we use to describe the age of geological features and to determine the relative order of past events. Here, we are talking about millions and billions of years. Let us discuss more details about these terms.

What are the various uses of radiocarbon dating ?

Radiocarbon dating is a method that provides objective age estimates for carbon-based materials that originated from living organisms. The impact of the radiocarbon dating technique on modern man has made it one of the most significant discoveries of the 20th century. Archaeology and other human sciences use radiocarbon dating to prove or disprove theories. Over the years, carbon 14 dating has also found applications in geology, hydrology, geophysics, atmospheric science, oceanography, paleoclimatology and even biomedicine. Radiocarbon carbon 14 is an isotope of the element carbon that is unstable and weakly radioactive.

Radioactive Dating

Radiometric dating or radioactive dating is any technique used to date organic and also inorganic materials from a process involving radioactive decay. The method compares the abundance of a naturally occurring radioactive isotope within the material to the abundance of its decay products, which form at a known constant rate of decay. All these methods are based on the fact the rate at which radioactive nuclei disintegrate is unaffected by their environment, it can be used to estimate the age of any material sample or object which contains a radioactive isotope. Calculations of the decay of radioactive nuclei are relatively straightforward, owing to the fact that there is only one fundamental law governing all decay process.
Furthermore, in an undeformed sequence of sedimentary rocks , each layer of rock is older than the one above it while electron spin resonance and thermoluminescence are the techniques in radioactive dating. In brief, relative dating and radiometric dating are two methods of dating fossils. Relative dating is the method of dating the relative age of geological events preserved in rock records depending on the relative ages of the strata. Here, strata are the many horizontal layers at the surface of the earth. Especially, relative dating is important for dating sedimentary and volcanic rocks.
