Offering in 1952 his new radiocarbon method for calculating the age of organic material (the time interval since the plant or the animal died), W. Libby clearly saw the limitations of the method and the conditions under which his theoretical figures would be valid: A.
Of the three reservoirs of radiocarbon on earththe atmosphere, the biosphere, and the hydrosphere, the richest is the lastthe oceans with the seas.
Suess explained the phenomenon by the fact that the increased industrial use of fossil carbon in coal and in oil changed the ratio between the dead carbon C12 and the C14 (radiocarbon) in the atmosphere and therefore also in the biosphere.
Whats at the bottom might be shattered rocks or impact melt or maybe a piece of meteorite.
History and Uses: Carbon, the sixth most abundant element in the universe, has been known since ancient times.
Amorphous carbon is formed when a material containing carbon is burned without enough oxygen for it to burn completely.
Scientist for the last hundred years have been searching for a crator or remnants of space rock.
Finally in 2008 scientist think they have found an impact site at the bottom of a nearby lake Cheko.
