Determine age fossils carbon dating
This is what archaeologists use to determine the age of human-made artifacts.The half-life of carbon-14 is only 5,730 years, so carbon-14 dating is only effective on samples that are less than 50,000 years old.Radiocarbon dating was invented in the 1940s by Willard F. Radioactive dating is used in research fields, such as anthropology, palaeontology, geology and archeology.Absolute dating tells when the fossil was formed, relative dating compares fossils to other fossils, some fossils cannot se absolute dating so they have to use both relative and absolute dating together. The first is relative dating which examines the layers of rock around the fossil to find an approximate date.Radioactive decay occurs at a constant rate, specific to each radioactive isotope.Since the 1950s, geologists have used radioactive elements as natural "clocks" for determining numerical ages of certain types of rocks. Radiocarbon dating involves determining the age of an ancient fossil or specimen by measuring its carbon-14 content.
A popular way to determine the ages of biological substances no more than 50,000 years old is to measure the decay of carbon-14 into nitrogen-14.There is also absolute dating in which geologists use "radioactive dating" to determine the absolute age of fossils or any specimen they wish to date. It decays to Nitrogen 14 and has a half life of 5,730 years.Typically, Carbon 14 is used for fossil dating for fossils 100-30,000 years old, but older than that, Potassium 40 or Rubidium 87 are more effective. Carbon 14 has a half life of 5,730 years and by checking the amount of the carbon 14 is in a fossil the can see how old it is. Absolute dating is the process of determining an approximate computed age in archaeology and geology.carbon dating, compares age of carbon particles which develop in fossils with ages of similarly mature carbon atoms to give the date... think may have to do with crystal lattice or wadawada..i wil pay attention nxt time Among many methods, carbon dating is most commonly used to date fossils.

Geologists can either use relative dating in which they relate the position of the fossils they found in strata to other substances found in other layers of the earth's crust, for which they know the date.
