Radiometric dating is used to determine the age of many materials on...

Before , ages for the Earth based on uranium/thorium/lead ratios were generally about a billion years younger than the currently popular billion years.

radiometric dating is based on-84

Radiometric dating is based on video

This assumption is backed by numerous scientific studies and is relatively sound.

However, conditions may have been different in the past and could have influenced the rate of decay or formation of radioactive elements.

These methods are largely independent of each other, based on separate observations and Age of the Earth and solar system from radiometric dating.

This is an informational tour in which students gain a basic understanding of geologic time, the evidence for events in Earth’s history, relative and absolute dating techniques, and the significance of the Geologic Time Scale.

We could put forward the following counter arguments to the constancy of these assumptions: a) The constancy of cosmic ray bombardment might be questioned.

The current high rate of entry might be a consequence of a disturbed post-Flood environment that altered the .

Many examples from literature show that the zero-reset assumption is not always valid.

Volcanic ejecta of Mount Rangitoto (Auckland, New Zealand) was found to have a potassium-40 age of 485,000 years, yet trees buried within the volcanic material were dated with the carbon-14 method to be less than 300 years old.

Carbon-14 comes from nitrogen and is independent of the carbon-12 reservoir.

If even a small percentage of the limestone deposits were still in the form of living marine organisms at the time of the Flood, then the small amount of carbon-14 would have mixed with a much larger carbon-12 reservoir, thus resulting in a drastically reduced ratio.
