Relative dating determining the sequence of geologic events

Which of these does a better job of describing my age? So, in both geology and paleontology, we want to be able to point to an object and say exactly how old it is.To do that, we have to learn a little bit about radioactive decay.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.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.Along the way, we'll learn how stratigraphic succession and radioactive decay contribute to the work of paleontologists.

Unlike relative dating, which only tells us the age of rock A compared to rock B, numerical dating tells us the age of rock A in x number of years.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.That means they don't really know how old their rocks actually are.The key in relative dating is to find an ordered sequence.
