The thing that makes this decay process so valuable for determining the age of an object is that each radioactive isotope decays at its own fixed rate, which is expressed in terms of its half-life.So, if you know the radioactive isotope found in a substance and the isotope's half-life, you can calculate the age of the substance. Well, a simple explanation is that it is the time required for a quantity to fall to half of its starting value.Relative dating is a scientific process of evaluation used to determine the relative order of past events, but does not determine the absolute age of an object.

For example: If an archaeologist is studying past civilizations, the archaeologist may be able to say that in a particular location the ruins of once civilization were found to have been build on another and so the layers unearthed in an excavation convey the sequence of historical occupations without revealing the actual dates.

If the archaeologist finds a sample suitable for carbon dating, then an absolute date may be assigned to an object.

Both are attempting to get information on the history of events.

The primary difference in relative dating and absolute dating is that absolute dating assigns an actual time or age to an event or object.

Learn about half-life and how it is used in different dating methods, such as uranium-lead dating and radiocarbon dating, in this video lesson. As we age, our hair turns gray, our skin wrinkles and our gait slows.

However, rocks and other objects in nature do not give off such obvious clues about how long they have been around.It works because we know the fixed radioactive decay rates of uranium-238, which decays to lead-206, and for uranium-235, which decays to lead-207.So, we start out with two isotopes of uranium that are unstable and radioactive.Short Answer: Radiometric dating is one type of method used in absolute dating.Both relative dating and absolute dating are procedures used to give temporal characteristics to a sequence of events.Radiometric dating determines how old something is using radioactive isotopes. Relative dating is used to determine the age of a fossil by looking at its position in layers of sedimentary rocks.
