Absolute dating carbon 14

With sensitive instrumentation, this range can be extended to 70,000 years.In addition to the radiocarbon dating technique, scientists have developed other dating methods based on the transformation of one element into another.Dendrochronology: Also known as tree-ring dating, the science concerned with determining the age of trees by examining their growth rings.Half-life: Measurement of the time it takes for one-half of a radioactive substance to decay.Radioactive decay: The predictable manner in which a population of atoms of a radioactive element spontaneously disintegrate over time.Stratigraphy: Study of layers of rocks or the objects embedded within those layers.If a certain kind of pollen is found in an archaeological site, scientists can check when the plant that produced that pollen lived to determine the relative age of the site.Absolute dating methods are carried out in a laboratory.

Carbon-14, a radioactive form of the element carbon, is created in the atmosphere by cosmic rays (invisible, high-energy particles that constantly bombard Earth from all directions in space).When the organism dies, the supply stops, and the carbon-14 contained in the organism begins to spontaneously decay into nitrogen-14.The time it takes for one-half of the carbon-14 to decay (a period called a half-life) is 5,730 years.When carbon-14 falls to Earth, it is absorbed by plants.These plants are eaten by animals who, in turn, are eaten by even larger animals.
