Carbon 13 isotope dating
Based on the estimated groundwater velocities, the approximate location of the recharge areas of these aquifers was identified.The groundwater ages calculated for Kuwait group aquifer varied from 800 a B.
Over the past 150 years (since humans began burning fossil fuels), the carbon isotope signature of the atmosphere has shifted more than 0.15 percent.
The number given after the atom name (carbon) indicates the number of protons plus neutrons in an atom or ion.
Atoms of both isotopes of carbon contain 6 protons.
It has become increasingly clear that these radiometric dating techniques agree with each other and as a whole, present a coherent picture in which the Earth was created a very long time ago.
Further evidence comes from the complete agreement between radiometric dates and other dating methods such as counting tree rings or glacier ice core layers.
