When an organism dies, the C-14 decays to N-14, or nitrogen 14. Scientists use the change in the ratio to see how much time has passed since the organism died.]]> 2016-03-04 20:08:48 UTC https://padlet.com/trey_williams/jw2h38ow928r/wish/99136152 ryan_lejeune https://padlet.com/trey_williams/jw2h38ow928r/wish/99137075 Radiocarbon forms in the Earth's upper atmosphere, it mixes with Carbon-12.]]> 2016-03-04 20:12:48 UTC https://padlet.com/trey_williams/jw2h38ow928r/wish/99137075 drew_hoffpauir https://padlet.com/trey_williams/jw2h38ow928r/wish/101639635 The half-life of carbon-14 is 5,730. That means radiocarbon dating is useful for measuring the age of the age of the remains of organisms that died up to about 60,000 years ago.]]> 2016-03-17 19:42:04 UTC https://padlet.com/trey_williams/jw2h38ow928r/wish/101639635
