Using radiometric dating how old is the earth Erotisk teen
What is less commonly known are any of the details of how the issue was settled: such as that the 4.5 billion year 'date' came from a single meteorite that was assumed to be the same age as the earth's core.
And since this favored 'date' is the only one that's trumpeted by the media it is the only date that many assume to be correct.
There is no conflict between science and the Bible..one needs is a proper understanding how to merge science and the Bible.
Prior to 1905 the best and most accepted age of the Earth was that proposed by Lord Kelvin based on the amount of time necessary for the Earth to cool to its present temperature from a completely liquid state.
The initial ratio has particular importance for studying the chemical evolution of the Earth's mantle and crust, as we discussed in the section on igneous rocks. If this happens, then the date obtained will be older than the date at which the magma erupted.
For example lavas dated by K-Ar that are historic in age, usually show 1 to 2 my old ages due to trapped Ar.
After the passage of two half-lives only 0.25 gram will remain, and after 3 half lives only 0.125 will remain etc.
However, none of the criticisms of young earth creationists have any scientific merit.
Other minerals that also show these properties, but are less commonly used in radiometric dating are Apatite and sphene.
