In 1905, Ernest Rutherford figured out that we could use radiation to establish the ages of rocks.By studying how the mass of uranium changed with radioactive decay, Rutherford was able to determine the age of a rock containing a uranium mineral. It meant that scientists could suddenly establish the actual ages of all their rocks and fossils!The first method that scientists use to determine the age of rocks is relative dating.In this method, scientists compare different layers of rock to determine an ordered sequence of events in geologic history.Free 5-day trial Learn how scientists determine the ages of rocks and fossils.We'll explore both relative and numerical dating on our quest to understand the process of geological dating.

He saw that it underwent radioactive decay, or emission of energetic particles to produce new elements.If I told you that I was 30 years old, that number would be my numerical age.If I told you I was 32 years younger than my mother, that number would be my relative age.Scientists piece together a story of how one event came before or after another.Relative dating cannot tell us the actual age of a rock; it can only tell us whether one rock is older or younger than another.
