Chitrangada (Chini) Datta from the Australian National University (anu.edu.au) looks at how relative time scales are worked out. This as part of a series of educational videos on reading the rocks.

This clip has been created by the Research School of Earth Sciences (rses.anu.edu.au). These resources are part of a comprehensive program, curriculum matched to the unit 'Introduction to Earth systems'.

This video touches on the following curriculum descriptors:
A relative geological time scale can be constructed using stratigraphic principles including superposition, cross cutting relationships, inclusions and correlation (ACSES016)

In this video, That Bio Doc discusses how radioactive isotopes such as carbon-14, uranium-238, uranium-235, and potassium-40 can be used to determine the age of a rock sample. Absolute dating techniques using these radioactive isotopes are the primary way in which the age of rock strata, including the fossils contained within them, are determined.
