Explain radiometric dating
This element is locked in tiny zircons within the granite. While it stays within the zircon for a period of time, being a very small atom, helium escapes the zircon within a few thousand years.
When creation scientists studied granite samples, they made interesting discoveries.
After the second half-life has elapsed, yet another 50% of the remaining parent isotope will decay into daughter isotopes, and so on.
For all practical purposes, the original isotope is considered extinct after 6 half-life intervals. A small portion of a meteorite is vaporized in the device forming ions.
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.
When a tree is cut down, these periods are exhibited in a cross section of the trunk in the form of rings.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.Many are also unaware that Bible-believing Christians are among those actively involved in radiometric dating.In the infancy of our home planet the entire earth was molten rock - a magma ocean.Since we can only measure as far back in time as we had solid rock on this planet, we are limited in how we can measure the real age of the earth.
