Question by twizz: How does radiometric dating assist researchers pinpoint the age of a fossil?In radiometric dating, researchers use the rate of decay of radioactive materials in rocks to estimate the absolute age of a rock.Ice outcrops provide accessible archives of old ice but are difficult to date reliably.

Radiometric dating allows researchers to discover fossils in only the lowest and oldest layers of sediment.

While the moment in time at which a particular nucleus decays is unpredictable, a collection of atoms of a radioactive nuclide decays exponentially at a rate described by a parameter known as the half-life, usually given in units of years when discussing dating techniques.

After one half-life has elapsed, one half of the atoms of the nuclide in question will have decayed into a "daughter" nuclide or decay product.

The technique successfully identifies valuable ice from the previous interglacial period at Taylor Glacier, Antarctica.

Our method will enhance the scientific value of outcropping sites as archives of old ice needed for paleoclimatic reconstructions and can aid efforts to extend the ice core record further back in time. Krypton was extracted from the air bubbles in four ∼350-kg polar ice samples from Taylor Glacier in the Mc Murdo Dry Valleys, Antarctica, and dated using Atom Trap Trace Analysis (ATTA).

I have every reason to believe that just as the marginalized European men want to show solidarity towards Asian women, who are still marginalized, paradoxically it is the women at the top who will eventually do something to improve a lot of men who are racing to the bottom of society.

Clearly, such huge time periods cannot be fitted into the Bible without compromising what the Bible says about the goodness of God and the origin of sin, death and suffering—the reason Jesus came into the world (See Six Days? He said, This only makes sense with a time-line beginning with the creation week thousands of years ago.
