Answer In relative-age dating, the age of species found in sedimentary rock layers is determined by the age of igneous rock. The age progression along each of these features has been estimated; the theory that these hot spots have remained fixed in position relative to each other has been tested. Relative dating does not give an exact date. You need to explain, using the chart below, the relative age of the fossils in relationship to the other fossils.
