At such speeds, the projecticle explodes on impact and carves out a round bowl-shaped depression on the surface. How can you distinguish an impact crater from a volcanic crater?Volcano craters are above the surrounding area on mountaintops while the craters from impacts are below the surrounding area with raised rims.(Psalm 19:1-3) The heavens do indeed declare the glory of God, but some people choose to believe that the heavens appeared by random chance out of nothing—a stance for which they are “without excuse.” Paul so forcefully points out in Romans -20 that can be understood “by the things that are made.” These people tend to support their beliefs with various scientific models such as the radioactive dating methods we have been examining in this series.This article will address the uranium-lead (U-Pb) and thorium-lead (Th-Pb) models.Most people think that radioactive dating has proven the earth is billions of years old.After all, textbooks, media, and museums glibly present ages of millions of years as fact.

These each have 19 protons and 21 neutrons in their nucleus.For every 100 K-40 atoms that decay, 11 become Ar-40.Cosmic rays enter the earth's atmosphere in large numbers every day.For example, every person is hit by about half a million cosmic rays every hour.It is not uncommon for a cosmic ray to collide with an atom in the atmosphere, creating a secondary cosmic ray in the form of an energetic neutron, and for these energetic neutrons to collide with nitrogen atoms.
