Parent daughter ratio radiometric dating christian people dating

Once scientists have determined the parent-daughter ratio, they can use this measurement along with half-life of the parent to calculate the age of a rock containing the radioactive isotope.

Radiometric dating has shown that very old rocks--3.5 billion years or older--occur on all the continents.

Calculate the age of the rock from the slope of the line.

Scientists assume that meteorites and moon rocks were not subjected to the extensive alteration that Earth rocks have undergone.

Note that at time 0, the time of the mineral's formation, the crystal contains only parent atoms.

At time 1, 50% of the parent atoms remain; at time 2, only 25% remain, and so on.

Scientists determined the Earth's age using a technique called radiometric dating.

Radiometric dating is based upon the fact that some forms of chemical elements are radioactive, which was discovered in 1896 by Henri Becquerel and his assistants, Marie and Pierre Curie.

Ideally, the mineral crystals in igneous rocks form a closed system--nothing leaves or enters the crystal once it is formed.

    --------------------------------------------------- Not a great deal, really. Although the project originally started at UC Davis (hence the name), and it has always been based there, most of the contributors have had little or no connection with this institution.
