updating ada legacy codes - Absolute dating vs realtive dating
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 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.
He could be pretty confident that his super awesome dinosaur was about 175 million years old.
Stratigraphic and fossil succession are good tools for studying the relative dates of events in Earth's history, but they do not help with numerical dating.
In fact, Paul already knows that coelophysis lived around 200 million years ago, while iguanodon lived around 150 million years ago.
So, what if Paul found that superus awesomus dinosaur fossil in this middle layer?
One of the biggest jobs of a geologist is establishing the absolute age, in years, of a rock or fossil.
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.
