Relative dating is the same as radioactive dating
Relative dating is the technique that attempts to roughly determine the age of a fossil using its position or location in relation to other fossils or remains in nearby strata (hence the name, "relative") In other words, to determine the age of a fossil using relative dating, one would look at the stratum the fossil was found in. In fact, it may contain coal or fossil fuels - which take, at the very least, thousands of years to form - that now appear near the very top!Then, one would compare the fossil's position in the stratum to the position of other nearby index fossils or remains. Such an inconsistency would, logically, confuse geologists in the future if they had no prior knowledge of the St. It is known that volcanic eruptions, such as the one at St. Not only that, but earthquakes and floods can also sometimes shift and mix strata and sediments.This is a very extensive decay rate, but is still useful to scientists.Much in the same way used to approximate the age of organic fossils, scientists use uranium-238's decay rate and the uranium-238 to lead-206 (which it decays into) ratio to approximate an age to assign to the object.Phrased simply, radioactive dating is the method that uses measurements relating to the radioactivity of the atoms in a fossil or an artifact. What "decay" means is that the atoms in the object or body become unstable, and, over time, begin to "decompose" by giving off radiation in the forms of subatomic particles (such as electrons and protons).There are different types of radiation: specifically, gamma, alpha and beta radiation. This process of radioactive decay eventually leads to the atoms becoming a different element and achieving stability.For example, in decomposing organic bodies - such as an animal carcass - carbon-14, an isotope of carbon, is present.Overtime, the C-14 atoms give off radiation, and, eventually, transform into nitrogen-14 atoms.
Summary Relative dating is determining the relative order of past events via determining the approximate age of geological features.

If a fossil is found, it means it is organic in nature, and thus has or will have contained C-14 atoms.
By using the known decay rate of C-14 as a reference and working out how much of the fossil's composition consists of C-14 and how much of it consists of N-14, they can approximate the age.
