Parent daughter ratio radiometric dating Instant live sex cam 1on1
The greater the initial concentration of the parent, the greater the concentration of the radiogenic daughter isotope will be at some particular time.
Thus, the ratio of the daughter to non-radiogenic isotope will become larger with time, while the ratio of parent to daughter will become smaller.
Many Christians have been led to distrust radiometric dating and are completely unaware of the great number of laboratory measurements that have shown these methods to be consistent.
There are over forty such techniques, each using a different radioactive element or a different way of measuring them.
For rocks that start out with a small concentration of the parent, the daughter/non-radiogenic ratio will not change quickly as compared to rocks starting with a large concentration of the parent.
To perform dating, a rock is crushed to a fine powder, and minerals are separated by various physical and magnetic means.
To determine the age, you need to know what the minerals are, and the half-life of the parent.
Spectroscopy is used to determine what the minerals are, and how much there is (you saw how to recognize the element in a gas in the spectroscopy lab - with a better spectroscope you can also determine the density and from that the number of particles.) The half life of isotopes is determined by theory, and confirmed with controlled experiments. Wiens has a Ph D in Physics, with a minor in Geology.
