A Little Astronomy and Geology 



forms, and thus the process of sedimentation began. Dur- 

 ing all of these millions of years of grinding, washing and 

 leveling of the earth's surface, it was being prepared for the 

 greatest event that has ever occurred since the universe 

 began — -namely, the creation of the first "Life Spark." All 

 the forces of Nature were at work — the electrons, the 

 atoms, the molecules, gravitation, adhesion, cohesion, light 

 and heat waves, chemical and magnetic forces, putting all 

 things in order for the coming "Life Spark." The poisonous 

 gases from the Innumerable volcanoes were being purified 

 and were now forming into an atmosphere composed mostly 

 of oxygen and nitrogen, the elements necessary to support 

 life. The atmosphere of today like all other things, has 

 passed through an evolutionary process. The original 

 atmosphere was squeezed out of the materials of which the 

 earth is formed, and its component parts were far different 

 in the early history of the earth from what it now is. 



The original oceans were composed mostly of fresh 

 water but throughout the centuries of erosion of the earth's 

 surface, the soluble salts were dissolved and carried by the 

 rivers into the oceans where they are now carried in solution. 

 The original oceans covered many portions of what are now 

 land and the present oceans now cover much land that was 

 once parts of the continents. The drilling for oil and gas in 

 Oklahoma and Kansas has furnished proof that great moun- 

 tain ranges and mountain peaks lie buried beneath the sedi- 

 mentary deposits of the grassy plains of these two states. 



The temperature of the earth had cooled, the atmos- 

 phere had been purified, the earth's elements had been com-
