Also, the difficulty of using carbon dating increases as objects grow older.
Living things have concentrations of carbon-14 in them that are identical to the concentrations of carbon-14 in the atmosphere at the time they die.
It is in knowing what made past cultures cease to exist that could provide the key in making sure that history does not repeat itself.
Over the years, archaeology has uncovered information about past cultures that would have been left unknown had it not been with the help of such technologies as radiocarbon dating, dendrochronology, archaeomagnetic dating, fluoride dating, luminescence dating, and obsidian hydration analysis, among others.
Archaeology has undoubtedly enriched mankind’s history like no other science.
There is a greater part of man’s unwritten past that archaeology has managed to unravel.
Tree-ring data are especially important in the correction process for dates older than 1000 BC.However due to the short half life of carbon-14, as stated previously it is only of use for dating objects that are less than 60,000 years old.This is a very small fraction of the 4.56 billion year history of Earth.Most carbon atoms (98.89 percent) are called carbon-12 because they have 6 neutrons and 6 protons in their nuclei.Most of the remaining atoms (1.11 percent) have 7 neutrons along with their 6 protons and are called carbon-13 atoms, but a very small quantity (called a trace amount) of carbon atoms have 8 neutrons and 6 protons. Carbon-14 atoms are radioactive and are referred to as radiocarbon.
