The craters on all of the moons except Io, Mercury, and most of the ones on Mars are from impacts.
The kinetic energy of the impacting meteorite or asteroid is converted into heat, sound, and mechanical energy---the projectile explodes on impact.
(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.
For every 100 K-40 atoms that decay, 11 become Ar-40.
Cosmic rays enter the earth's atmosphere in large numbers every day.
One out of every 10,000 Potassium atoms is radioactive Potassium-40 (K-40).
These each have 19 protons and 21 neutrons in their nucleus.
Some of them have orbits that cross the orbits of the planets and moons.
When they get close enough to a planet or moon, they will be pulled in by the large body's gravity and strike the surface at a speed of at least the escape velocity of the planet or moon, i.e., faster than a bullet.
Geologists have used this method to date rocks as much as 4 billion years old.
It is based on the fact that some of the radioactive isotope of Potassium, Potassium-40 (K-40) ,decays to the gas Argon as Argon-40 (Ar-40).
By comparing the proportion of K-40 to Ar-40 in a sample of volcanic rock, and knowing the decay rate of K-40, the date that the rock formed can be determined.
Potassium (K) is one of the most abundant elements in the Earth's crust (2.4% by mass).
For example, every person is hit by about half a million cosmic rays every hour.Tags: Adult Dating, affair dating, sex dating
