A level physics carbon dating

Familiar to us as the black substance in charred wood, as diamonds, and the graphite in “lead” pencils, carbon comes in several forms, or isotopes.

One rare form has atoms that are 14 times as heavy as hydrogen atoms: carbon-14, or C ratio gets smaller.

However, open-air nuclear testing between 1955–1980 contributed to this pool.

The different isotopes of carbon do not differ appreciably in their chemical properties.

So, we have a “clock” which starts ticking the moment something dies.

Obviously, this works only for things which were once living.

Many are also unaware that Bible-believing Christians are among those actively involved in radiometric dating.

Radioactivity at 16 level differs from that at 14-16 level primarily in the application of mathematical interpretation that is required.

It is useful to revise the subject at the lower level before beginning this section of study.

We will deal with carbon dating first and then with the other dating methods.

Carbon has unique properties that are essential for life on Earth.
