Application of carbon dating in archeology
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.
These remains include the fossils (preserved bones) of humans, food remains, the ruins of buildings, and human artifactsitems such as tools, pottery, and jewelry.
Archaeologists concentrate their studies on past societies and changes in those societies over extremely long periods of time.He calculated the modern rate of salt delivery to the oceans, and suggested that the present salinity of ocean water would take at least 100 million years to develop.In the 1860's, English physicist Lord Kelvin disagreed with Charles Lyells proposition that the earth behaves in a uniform, unchanging manner.Radiometric dating--the process of determining the age of rocks from the decay of their radioactive elements--has been in widespread use for over half a century.There are over forty such techniques, each using a different radioactive element or a different way of measuring them.
