PHYSICS
Asked by Liam

How can the absolute age of earth layers be determined?

We can work out the age by measuring the amount of certain radioactive elements. When the rocks form, they will trap some of this radioactive material which will decay over time. By measuring how much is left(undecayed) and using the half life of the element, we can work out the age. It is very similar to carbon dating but carbon dating only works on organic matter
