The term relative dating is distinguished from absolute dating to make it clear that one does not get a specific estimate of the age of an object from relative dating , but one does get such an estimate of true age from absolute dating. There are several techniques employed in both sets of methods. Radiometric dating is one type of absolute dating. Sciences such as geology, paleontology and archeology are very interested in identifying the age of objects found and these scientists sometimes use both relative dating or absolute dating to characterize the age of the objects they study.

Share facts or photos of intriguing scientific phenomena. Did You Know? Although both relative and absolute dating methods are used to estimate the age of historical remains, the results produced by both these techniques for the same sample may be ambiguous. Geological specimens that are unearthed need to be assigned an appropriate age. To find their age, two major geological dating methods are used. These are called relative and absolute dating techniques.
What Is the Difference Between Relative Dating and Radiometric Dating?
The meteorites and moon rocks are believed to have formed virtually at the same time with earth and are therefore, considered to be of the same age as earth. Absolute dating tells when the fossil was formed, relative dating compares fossils to other fossils, some fossils cannot se absolute dating so they have to use both relative and absolute dating together. Relative dating is the science determining the relative order of past events, without necessarily determining their absolute age Absolute dating is the process of determining an approximate computed age in archaeology and geology. Absolute dating is the process of determining an approximate computed age in archaeology and geology.
Relative dating and radiometric dating are used to determine age of fossils and geologic features, but with different methods. Relative dating uses observation of location within rock layers, while radiometric dating uses data from the decay of radioactive substances within an object. Relative dating observes the placement of fossils and rock in layers known as strata. Basically, fossils and rock found in lower strata are older than those found in higher strata because lower objects must have been deposited first, while higher objects were deposited last. Relative dating helps determine what came first and what followed, but doesn't help determine actual age.
