Carbon 14 and potassium argon dating methods ontario adult dating

Any scientific study of the past, including the geologic past, relies on the use of dating methods to determine the age of sites, landforms, sediments or geologic events.

A variety of dating methods are available, and the scientist must decide which method will provide the most accurate results in each case.

This gives us the impression that all but a small percentage of the dates computed by radiometric methods agree with the assumed ages of the rocks in which they are found, and that all of these various methods almost always give ages that agree with each other to within a few percentage points.On the surface, radiometric dating methods appear to give powerful support to the statement that life has existed on the earth for hundreds of millions, even billions, of years.We are told that these methods are accurate to a few percent, and that there are many different methods.This is why most people say carbon dating is only good for objects less than 40,000 years old.Nothing on earth carbon dates in the millions of years, because the scope of carbon dating only extends a few thousand years.
