Dating rocks and fossils and geologic events
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.
And, what about other findings like fossil fish, plants and insects?The most common form of relative dating is called stratigraphic succession.This is just a fancy term for the way rock layers are built up and changed by geologic processes.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.
