The difference between relative dating and absolute dating is that relative dating is a method of sequencing events in the order in which they happened.

There are several techniques employed in both sets of methods. Long Answer: 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.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.Scientists can use certain types of fossils referred to as index fossils to assist in relative dating via correlation.Index fossils are fossils that are known to only occur within a very specific age range.Your goal is to study the smooth, parallel layers of rock to learn how the land built up over geologic time.

Now imagine that you come upon a formation like this: What do you think of it? How can you make any conclusions about rock layers that make such a crazy arrangement?

The study of fossils and the exploration of what they tell scientists about past climates and environments on Earth can be an interesting study for students of all ages.

Teaching about Earth's history is a challenge for all teachers.

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.

Using relative dating the fossil is compared to something for which an age is already known.
