Find additional lessons, activities, videos, and articles that focus on relative and absolute dating.C) dating usually want to know about the radiometric dating methods that are claimed to give millions and billions of years—carbon dating can only give thousands of years.Obviously, this works only for things which were once living.It cannot be used to date volcanic rocks, for example.In summary, the carbon-14 method, when corrected for the effects of the flood, can give useful results, but needs to be applied carefully.It does not give dates of millions of years and when corrected properly fits well with the biblical flood.One rare form has atoms that are 14 times as heavy as hydrogen atoms: carbon-14, or C ratio gets smaller.
Since the flood was accompanied by much volcanism (see Noah's Flood…, How did animals get from the Ark to isolated places? ), fossils formed in the early post-flood period would give radiocarbon ages older than they really are.
Anything over about 50,000 years old, should theoretically have no detectable C.
That is, they take up less than would be expected and so they test older than they really are.
By dating these surrounding layers, they can figure out the youngest and oldest that the fossil might be; this is known as "bracketing" the age of the sedimentary layer in which the fossils occur.
