carbon 14 is a carbon with a radioactive isotope that contains 8 protons and 6 neutrons. when a person dies, the body releases more and more c-14 from it and eventually there will be no more in about 60,000 years later. using c-14, we can find out how old living stuff was, including plants, animals, and humans. tree ring dating was known for a long time. when you look at a cut down tree, you can see that there are rings on it. every year, a trees tissues form a ring. when the weather was dry, there are less tissues so the ring is small and shriveled. when the weather is wet, then there are more tissues and the tree is healthier so it forms a bigger ring. using both of the ways, we can find out when a living being died, and why.
