Radioactive potassium (40potassium) decays into argon over time, so the age of certain rocks or minerals can be discovered by measuring the amount of argon they contain.

It is no secret that expats from every corner of the globe have been taking off and leaving their debts behind.

Many people have lost their jobs and had visas canceled.

As a result, there is a changing ratio of carbon-14 to the more atomically stable carbon-12 involves actually counting individual carbon-14 atoms.

This allows the dating of much older and smaller samples but at a far higher cost.
