Also, an increase in the solar wind or the Earth's magnetic field above the current value would depress the amount of carbon created in the atmosphere. However, local eruptions of volcanoes or other events that give off large amounts of carbon dioxide can reduce local concentrations of carbon and give inaccurate dates. Relative Dating with Fossils: Radiocarbon datingalso known as carbon dating or simply carbon dating, is a method used to determine the age of organic material by measuring the radioactivity of its carbon content.

Geologists use radiocarbon to date such materials as wood and pollen trapped in sediment, which indicates the date of the sediment itself. After an organism has been dead for 60, years, so little carbon is left that accurate dating cannot be established. Instead, they are a consequence of background radiation on certain minerals.
