Difference between relative and chronometric dating
We'll explore both relative and numerical dating on our quest to understand the process of geological dating.Along the way, we'll learn how stratigraphic succession and radioactive decay contribute to the work of paleontologists.
give the time of an event with reference to another event that is not worldwide in scale.
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?
Relative dating helps determine what came first and what followed, but doesn't help determine actual age.
Radiometric dating, or numeric dating, determines an actual or approximate age of an object by studying the rate of decay of radioactive isotopes, such as uranium, potassium, rubidium and carbon-14 within that object. This rate provides scientists with an accurate measurement system to determine age.
