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.
It is one of classical archaeology's great unsolved problems.
Radiocarbon is not stable; over time radiocarbon atoms decay into nitrogen atoms.
The ratio of radiocarbon to stable carbon atoms in the atmosphere has varied in the past.
This is because the amount and strength of cosmic radiation entering the earth's atmosphere has varied over time.
Along the way, we'll learn how stratigraphic succession and radioactive decay contribute to the work of paleontologists.
Consider the following scenario: Paul the Paleontologist is a very famous scientist who has studied dinosaur bones all over the world.
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.
