relative and absolute. relative is determining the relative order of past events, without necessarily determining their absolute age. Absolute is the process of determining an approximate computed age in archaeology and geology.
Index fossils
relative dating
index fossils
Those types of fossils are called index fossils.

In order to be useful in determining the relative ages of rocks, an indicator must provide different indications for rocks of different ages, right? So how could something which doesn't change over time be useful?
The two methods are "RELATIVE DATING" and "ABSOLUTE DATING". :)
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.
relative dating
fossils can be used to determine the relative age of rock layer by using the classification of fossils to find the relative ages of rocks in which fossils are found. :] hoped i helped you out.

By examining fossils and by determining their relative and absolute ages, scientists have collected evidence that supports the theory that species changed over time.
The position of fossils in sedimentary rock layers.
Scientists can compare the ages of the fossils in one layer of the earth and then compare thoes to fossils in another layer of the earth. The one that is deeper is most likely to be older:)
