What is carbon dating wikianswers

An equation used is t = (1/c)Ln(1 (D/P)) Where c is the decay constant D is number of daughter atoms (number decayed) P is the number of parent atoms (number undecayed) t is the age of the object.

Another common technique in dating an object is carbon dating.

This preserved their bodies from prey and destruction by the current. Due to the presence of carbon-14, carbon film fossils are relatively easy for scientists to date.

Plants absorb carbon-14 from the air, and animals consume it when they eat plant life.

As a "for instance" we might look at uranium-lead dating.

This dating method can deliver results accurate to a million or two years in a billion years. Radioactive dating is also known as Radiometric dating.

Carbon dating has the peculiar property that it works primarily on dead things.

Unlike trace fossils, molds and casts, which form a three-dimensional shape of the object or organism, carbon film fossils are two-dimensional, like a drawing.One such example is potassium-argon dating, where potassium decays into argon.The proportion of potassium to argon suggests how old the object in question is.Most fossils contain a small amount of carbon, but carbon film fossils are primarily composed of carbon. When an organism dies or a leaf falls, it sinks into the earth's layers and decomposes.A carbon film is made when the oxygen, hydrogen and nitrogen of the organism disappear, leaving a thin layer of carbon.

The amount of carbon-14 depends on the amount of radiation permeates the ozone and thus the amount could be changing. Accuracy radioactive dating is called radiometric dating. Radioactive dating of rock samples determines the age of rocks from the time it was formed.
