The radiometric techniques that give absolute dating estimates are based on radioactive decay of elements such as uranium. Looking at how rock formations are structured, a geologist may be able to say which rock was developed in which layer in a particular order but not be able to determine that actual geologic age of the layers.

Geologists also have radiometric methods for absolute dating based on radioactive decay of certain elements.

Very often historical evidence is found in layers and older layers are further down that the top layers.

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

Your welcome for helping you with Biology Homework.... Both are attempting to get information on the history of events.

Tools like radiometric dating use radioactive isotopes and known decay rates… relative is determining the relative order of past events, without necessarily determining their absolute age.

However, carbon dating is an absolute dating technique that can give an estimate of the actual age of an artifact and thus an estimate of the age of other objects in the same layer.

Radiometric dating, based on known rates of decay of radioactive isotopes in objects, allows a specific age of an object to be determined to some degree of accuracy.Radioactive dating allows us to find an approximate date. Relative age 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 or date of an event.So if something is dated about a thousand years ago plus or minus… Relative dating gives a relative answer -10 years after the end of the civil war. Both relative dating and absolute dating are complimentary tools tools used to assign temporal characteristics to a sequence of events.Similarly, relative dating is done by paleontologists who find layers of fossils.

By deducing which fossils are formed in the sequence of time, the periods when the particular fossilized entities existed can be arranged in order without the actual dates of when the fossils were laid down.

Both relative dating and absolute dating are procedures used to give temporal characteristics to a sequence of events.
