The highest rate of carbon-14 production takes place at altitudes of 9 to 15 km (30,000 to 50,000 ft).
At high geomagnetic latitudes, the carbon-14 spreads evenly throughout the atmosphere and reacts with oxygen to form carbon dioxide.
So, every living thing is constantly exchanging carbon-14 with its environment as long as it lives. The carbon in its body will remain until it decomposes or fossilizes.
The amount of carbon-14 gradually decreases through radioactive beta decay with a half-life of 5,730 years.
If one knows how much of this radioactive material was present initially in the object (by determining how much of the material has decayed), and one knows the half-life of the material, one can deduce the age of the object.
You can also find them listed alphabetically by author on the Website Library page.
Each listing includes a brief description of its content.
However, archaeology is distinct from paleontology and studies only past human life.Archeology is the scientific study of past human culture and behavior, from the origins of humans to the present.Archaeology studies past human behavior through the examination of material remains of previous human societies.Archaeology is an important field of anthropology, which is the broad study of human culture and biology.Archaeologists concentrate their studies on past societies and changes in those societies over extremely long periods of time.
