Earth dating methods How Science Figured Out the Age of Earth

Earth dating methods, non-radiometric dating

We know the Earth is old. But how do we know its age?

View Table of Contents. For the case of alpha decay, [ In other words, the measurements show that the field has been diverging from the shape that would be expected of a theoretical ideal magnet, more than the amount of energy has actually been changing. For this reason, the earths dating methods of such dating methods are not treated with as much confidence.

The Earth's magnetic field is thought to arise from circulating electic currents in the Earth's molten metalic core, and scientists agree that the field is weakening. It follows that radioactive decay rates were much higher in the past. Let's take a deeper look into the theory of accelerated nuclear decay. The majority of the 70 well-dated meteorites have ages of 4.

But doesn't it seem strange that after more thanyears earth's population is still only 7 billion? Russell, author of the article on radioactive dating, was familiar to me for his part in developing the Hetzsprung-Russell diagram for stars, but I was surprised to discover that he was also the Russell of Russell-Saunders coupling, important in atomic structure theory.

Strengths and weaknesses of radiometric and other dating methods

This probability of decay is the decay constant. While this is negligible compared to the processes of erosion on the Earth about a shoebox-full of dust per acre per yearthere are no such processes on the Moon.

Morris chose to pick obsolete data with known problems, and call it the "best" measurement available. In the Abstract, Snelling and Rush conclude with:. He inferred that where the layers are not horizontal, they must have been tilted since their deposition and noted that different strata contain different kinds of fossil. Using radiometric techniques, the oldest dated minerals 4.

The technique gave 90 million years, but took no account of the non-constant erosion rate, or the loss and recycling of salt, or the fact that salt is obtained from other sources as well as earths dating methods.

For all Christians this should be:. An excellent, detailed exposition of the means by which the Earth's age is known, as well as the history of attempts to estimate that value, is given in Dalrymple An exact computation of decay rates is, of course, much more complicated, since it requires a detailed understanding of the shape of the potential barrier.

If no new comets are being generatedit would appear that no short-period comets can survive more than about 10, years - implying a young earth. A curious and unbiased observer could quite reasonably refuse to even listen to the creationists until they "clean house" and stop pushing these arguments.
