What is uranium 238 used for dating rocks

On the cover of your ESRT in the top left box you will find the Radioactive Decay Data for four isotopes which we will focus on.Carbon 14 occurs naturally, and is absorbed by all living things when we eat and drink.

The Bible gives a much different picture and explains that relying on man’s reasoning is foolishness.There are three main assumptions that must be made to accept radiometric dating methods.These must be accepted on faith in uniformitarian and naturalistic frameworks.Because its half-life is so long it is useful for dating the oldest rocks on Earth, but not very reliable for rocks under 10 million years old. This is ten times the age of the Earth, so very little Rubidium has decayed at all.For this reason WE WILL NEVER CHOSE TO USE THIS ISOTOPE!Some of the common isotope pairs used are K-Ar, Rb-Sr, Pb-Pb, and U-Pb.

Carbon-14 dating is another common technique, but it can only be used on carbon-containing things that were once alive.

Most scientists and many Christians believe that the radiometric dating methods prove that the earth is 4.5 billion years old.

The textbooks speak of the radiometric dating techniques, and the dates themselves, as factual information.

Uniformitarian geologists use so-called dating methods to determine the ages of the surrounding rocks.

Certain types of rocks, especially those that form from magma (igneous), contain radioactive isotopes of different elements.

When we die, we no longer ingest C14, and it begins to decay and turn into N14.
