Young earth radiometric dating antonio banderas salma hayek dating

The oldest reliably dated rock formation is in Greenland, where several different isotopes were used to find an age of 3.6 billion years.

To find older rocks that haven’t been eroded, we need to look beyond Earth.

In this way, multiple trees can be used to build a master chronology for a forested region.

Once the rock hardens, however, all the Argon-40 is trapped in the sample, giving us an accurate record of how much Potassium-40 has decayed since that time.

So, if we find a rock with equal parts Potassium-40 and Argon-40, we know that half the Potassium-40 has decayed into Argon-40, and that the rock hardened 1.3 billion years ago.

As time passes, a rock will have more and more Argon-40 and less and less Potassium-40.

Radiometric dating is possible because this decay occurs at a known rate, called the “half-life” of the radioactive element.

Many independent measurements have established that the Earth and the universe are billions of years old.

Geologists have found annual layers in ice that are easily counted to multiple tens of thousands of years, and when combined with radio isotope dating, we find hundreds of thousands of years of ice layers.These methods are largely independent of each other, based on separate observations and arguments, yet all point to a history much longer than 10,000 years.As Christians, we believe that God created the world and that the world declares his glory, so we can’t ignore what nature is telling us about its history.A tree’s age can be found by simply counting its rings.By comparing the pattern of thick and thin rings to weather records, scientists can verify that the method is accurate.Radiometric dating requires that one understand the initial ratio of the two elements in a given sample by some means.
