Question
Radiometric dating techniques indicate that the Ear
th is _____________ of times older
than that--approximately ____ ____________________
_____.
However, some Christians suggest that the geologic
dating techniques are
___________, that they are wrongly ____________, or
that they are confusing at best.
Unfortunately, much of the literature available to
Christians has been either
_______________ or difficult to understand, so that
confusion over dating techniques
continues.

over 10
21
(1 with 21 zeros behind) atoms. Even if only one t

in one year, this is still ____________ of decays,
each of which can be counted by a
radiation detector!
All of the half-lives are known to better than abou

_________has been dead_____________.
The half-life for the Berylllium-10 Boron-10 pair
is ____________1.52 million______years.
For example, recall that only one ___gram____ of ma
terial contains
over 10
21
(1 with 21 zeros behind) atoms. Even if only one t
rillionth of the atoms decay
in one year, this is still ____millions________ of decays,
each of which can be counted by a
radiation detector!
All of the half-lives are known to better than abou
t __two___ percent except for rhenium
