Radiometric dating of earth 34 turkey online email contact dating site turkey
Thus, the geologic timescale and radiometric dating have been developed in an effort to determine the age of the earth.
The older of the two dating methods, the geologic timescale, is actually a circular argument and is therefore considered by many scholars to be weak.
For biologists, even 100 million years seemed much too short to be plausible.
In Darwin's theory of evolution, the process of random heritable variation with cumulative selection requires great durations of time.
Nevertheless, the geologic timescale was thought to have been redeemed and refined with the advent of radiometric dating.
Radiometric dating is more objective, and thus, more substantial.
giving a lower limit for the age of the Solar System.
It is hypothesised that the accretion of Earth began soon after the formation of the calcium-aluminium-rich inclusions and the meteorites.
His calculations did not account for heat produced via radioactive decay (a then unknown process) or, more significantly, convection inside the Earth, which allows the temperature in the upper mantle to remain high much longer, maintaining a high thermal gradient in the crust much longer. Can we determine the age of the earth, and if so, how?
