Carbon dating explanation for kids
When they find one, they gather a sample of the hardened lava and send it off to a laboratory to test it for radioactive elements.When a volcano erupts, hot, molten rock (called “lava”) from deep inside the Earth is released. Elements are the “building-blocks” of the universe (for example, water is made from the elements hydrogen and oxygen).
C in the atmosphere haven’t been constant throughout history (for instance, Noah’s Flood lowered the total amount of available carbon by burying lots of animals and plants).
So something that lived (and died) when the proportion of C was less than normal would appear to have died more years ago than it actually did (for example, it might give an age of 3,000 years before the present, rather than its true age of 2,000 years).
The article is in straightforward language and the non-technical reader could profitably work through it.
, we find that this ration is the same if we sample a leaf from a tree, or a part of your body.
Think of it like a teaspoon of cocoa mixed into a cake dough—after a while, the ‘ratio’ of cocoa to flour particles would be roughly the same no matter which part of the cake you sampled.
