Carbon dating for kids should age matter when dating
Radiocarbon dating involves determining the age of an ancient fossil or specimen by measuring its carbon-14 content.Carbon-14, or radiocarbon, is a naturally occurring radioactive isotope that forms when cosmic rays in the upper atmosphere strike nitrogen molecules, which then oxidize to become carbon dioxide.His radiocarbon dating technique is the most important development in absolute dating in archaeology and remains the main tool for dating the past 50,000 years.How It Works: Carbon has 3 isotopic forms: Carbon-12, Carbon-13, and Carbon-14.

As long as there is organic material present, radiocarbon dating is a universal dating technique that can be applied anywhere in the world.
Natural disasters like floods can sweep away top layers of sites to other locations.
Absolute dating represents the absolute age of the sample before the present.
Green plants absorb the carbon dioxide, so the population of carbon-14 molecules is continually replenished until the plant dies.
Carbon-14 is also passed onto the animals that eat those plants.
