Radiometric age dating examples

distance = rate x time With radiometric dating we're instead looking to find the time (or age.) The formula would look like this: time = distance / rate So far they've been able to prove that the rate of decay is a constant so we've got one variable.

During the race you have to watch the swimmer and count how many laps he has swum so you know that he has done 1,500 metres.

You can get any date you like depending on the assumptions you make.

And that is what geologists do—they make up an assumed geological history for rock depending on the numbers that come from the geochronology lab that measures the isotopes in the rocks now.

Once we understand what we actually need to do we can apply the same principles to radioactive dating, and see if the methods do what they are claimed to do.
