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.
The circumstances of the object may allow one to say that one object is older than another without being able to assign a particular age to the objects.
Relative dating is any scientific process of evaluation used to determine the relative order of past events, but does not determine the absolute age of an object.
Long Answer: Sciences such as geology, paleontology and archeology are very interested in identifying the age of objects found and these scientists sometimes use either relative dating or absolute dating to characterize the age of the objects they study.
Learn about different types of radiometric dating, such as carbon dating.
Understand how decay and half life work to enable radiometric dating.
A link is provided to the Wikipedia article on radiometric dating to get you more information.
Fossils are generally found in sedimentary rock not igneous rock.Scientists date igneous rock using elements that are slow to decay, such as uranium and potassium.By dating these surrounding layers, they can figure out the youngest and oldest that the fossil might be; this is known as "bracketing" the age of the sedimentary layer in which the fossils occur.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.The importance of radiometric dating is that it allows us to tell how old some things are.Both are attempting to get information on the history of events.
