Relative dating techniques for kids
So based on this ratio, and I go into much more detail in other videos, you can figure out how old these things are and you get reasonably precise, within a couple of a hundred, hundreds of years.If you want to go further into the past, there's things like potassium-argon dating, which is once again taking a radioactive form of potassium and using the idea that it decays into argon.
And so based on the ratio between the carbon-14 to the carbon-12, and it takes roughly 5,000 years, 5,730 years to be exact, for roughly half of the carbon-14 to decay into carbon-12.
And so you have to take it all with a grain of salt.
At the extreme form, they might have eliminated some of these groups and then only they were around to say what actually happened.
But even in the written, you've gotta wonder what's added over each generation.
You can imagine people embellishing, making the story a little bit better.
