Scientists use two kinds of dating techniques to work out the age of rocks and fossils. The first method is called relative dating. The second method is called absolute dating and is done by analysing the amount of radioactive decay in the Index fossils are fossils that can be used to date the rock in which they are found. David has taught Honors Physics, AP Physics, IB Physics and general science courses. Radiometric dating is a method used to figure out how old rocks are by looking at Using these methods, we've even been able to figure out the age of the Earth A related method we use to date rock is the use of reference fossils .
