Radiometric dating reveals that volcanic rock samples are older if they have a
The assumption that the geologic column is a base from which to calibrate the C dates is not wise. With a half-life of only years, carbon dating has nothing to do with dating the geological ages! Whether by sloppiness or gross ignorance, Dr. Hovind is confusing the carbon "clock" with other radiometric "clocks.

Hotspot geology , Hawaiian — Emperor seamount chain , and Evolution of Hawaiian volcanoes Tectonic plates generally focus deformation and volcanism at plate boundaries. Tuzo Wilson proposed the hotspot theory to explain these zones of volcanism so far from regular conditions,  a theory that has since come into wide acceptance. Wilson proposed that mantle convection produces small, hot buoyant upwellings under the Earth's surface; these thermally active mantle plumes supply magma which in turn sustains long-lasting volcanic activity. This "mid-plate" volcanism builds peaks that rise from relatively featureless sea floor, initially as seamounts and later as fully-fledged volcanic islands. The local tectonic plate in the case of the Hawaii hotspot, the Pacific Plate slowly slides over the hotspot, carrying its volcanoes with it without affecting the plume.

Radiometric Dating and the Geological Time Scale
Nonetheless, our solar system and Earth take on great importance to our understanding of the universe because they were produced by the same processes that formed other stars and planets. The planet we live on is an accessible product of the evolution of a star; by studying it and our neighbors, the Sun and planets, we can learn much about the mechanics of planet formation and evolution. At the outset, it is important to note that we assume that the physical and chemical laws that govern nature are constant. For example, we use observations about how chemical reactions occur today, such as the combination of oxygen and hydrogen at specific temperatures and pressures to produce water, and infer that similar conditions produced the same results in the past. This is the basic assumption of all sciences.
Consider also the most popular explanation offered for the photo right , that a concretion formed around an s-era hammer as minerals precipitated out of the surrounding limestone. From Adam until Real Science Radio , in only generations! Another paper, in the American Journal of Physical Anthropology Eugenie Scott 's own field on High mitochondrial mutation rates , shows that one mitochondrial DNA mutation occurs every other generation, which, as creationists point out , indicates that mtEve would have lived about generations ago. That's not so old! As our List of Not So Old Things this web page reveals, by a kneejerk reaction evolutionary scientists assign ages of tens or hundreds of thousands of years or at least just long enough to contradict Moses' chronology in Genesis.
