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.
That means they don't really know how old their rocks actually are.
The key in relative dating is to find an ordered sequence.
Scientists piece together a story of how one event came before or after another.
Scientists are always spouting information about the ages of rocks and fossils. Well, they figure it out using two different methods: relative dating and numerical dating.
Let's find out more about these geological dating methods in order to understand how Paul the Paleontologist can be so sure about the age of his dinosaur 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.Recently, he appeared on the evening news to talk about a new dinosaur he just discovered. Paul says he can tell from the fossils that superus awesomus lived on Earth about 175 million years ago.Paul is super awesome, so I'm going to take him at his word.But really, how do scientists figure out how old their dinosaur bones are?And what about other findings like fossil fish, plants and insects?
