Fossils can be dated relative to one another by noting their positions in layers of rocks, known as strata as shown in the animation (right), fossils found in lower strata were generally deposited earlier and are older.
Learn about different types of radiometric dating, such as carbon dating.
Understand how decay and half life work to enable radiometric dating.
Using relative dating principles and the position of layers within rock, it is possible to reconstruct the sequence of geologic events that have occurred at a site in the image below, cliffs along the snake you have just used the principle of superposition to interpret the relative ages of the layers this principle states that in a.
Relative dating does not provide actual numerical dates for the rocks.
Bring relative dating principles to life with the activity Rock layers and relative dating.
Students begin by observing a photograph and a diagram of rock layers near Whanganui, watch an animation about how the layers were formed, then use an interactive labelling diagram to work out the order in which the rocks were created.
That fossil species may have been dated somewhere else, so you can match them and say that your fossil has a similar age.
Some of the most useful fossils for dating purposes are very small ones.
