Carbon dating volcanic rock

Obviously both sides of this debate have agendas to promote, and that means that any summary you're likely to read was probably motivated by one agenda or the other.Let's begin with a basic understanding of the radiometric dating technique used, K-Ar, or potassium-argon.Young Earthers point to an infamous dating error as evidence that the Earth is only as old as the Bible says.

Progressively through time, the carbon-14 atoms decay and once again become nitrogen-14.

The results came back dating the rock to 350,000 years old, with certain compounds within it as old as 2.8 million years. Austin's conclusion is that radiometric dating is uselessly unreliable. Austin chose a dating technique that is inappropriate for the sample tested, and charged that he deliberately used the wrong experiment in order to promote the idea that science fails to show that the Earth is older than the Bible claims.

Yet the experiment remains as one of the cornerstones of the Young Earth movement.

The universe is full of naturally occurring radioactive elements.

Radioactive atoms are inherently unstable; over time, radioactive "parent atoms" decay into stable "daughter atoms." When molten rock cools, forming what are called igneous rocks, radioactive atoms are trapped inside. By measuring the quantity of unstable atoms left in a rock and comparing it to the quantity of stable daughter atoms in the rock, scientists can estimate the amount of time that has passed since that rock formed.
