Plants absorb that carbon through photosynthesis, and animals via plants.When they die, however, the radioactive carbon decays at a known rate.An examination of sedimentary rocks worldwide shows a striking consistency with the unimaginably massive Flood that wiped out whole environments.It caused massive sedimentary layering and sorting and fossilizing of the creatures buried therein.

In fact, the very concept of strata representing long ages does not come from the rock strata themselves.Why does the lava dome provide an opportunity to test the accuracy of radioisotope dating? First, radioisotope dating methods can be used mainly on volcanic (igneous) rock, such as dacite.(Fossil-bearing sedimentary rock cannot be directly dated radioisotopically.) Second, the date of formation of the dacite is known.And today we know through lab experiments and natural disasters (such as the eruption of Mt. Helens) that major layering of rock strata can happen catastrophically in a short period of time.Young-earth creation geologists have long held that most sedimentary strata resulted from waterborne deposits during Noah’s Flood.
