Define absolute and relative dating
Potassium-40 is a radioactive isotope of potassium that decays into argon-40.The half-life of potassium-40 is 1.3 billion years, far longer than that of carbon-14, allowing much older samples to be dated.
That is the relative location of Missouri based on its location within the United States.
Both relative location and absolute location are geographic terms used to describe the location of a place on the Earth's surface.
They are each unique in their ability to pinpoint a location on Earth.
Some scientists prefer the terms chronometric or calendar dating, as use of the word "absolute" implies an unwarranted certainty and precision.
Absolute dating provides a computed numerical age in contrast with relative dating which provides only an order of events.
