ATMOSPHERE |
The earth's atmosphere is a mixture of several different gases. Clean, dry air has the following composition by volume; Nitrogen 78%; Oxygen 21%; Argon 0.93%; Carbon Dioxide 0.035%; other gases 0.035%. From the perspective of creation, this distribution of gases is not accidental but shows planning and design. People and animals utilize the oxygen portion of air. The abundant nitrogen is simply breathed in and out with no effect. However, there is a reason for this. If oxygen were the dominant gas in the atmosphere, spontaneous fires would break out world wide. Oxygen is extremely flammable, while nitrogen is not. It appears that nitrogen has been provided to safely dilute the oxygen. Calculations show that an atmosphere with 25% oxygen would be explosive. At the other extreme, a reduction to 15% oxygen would be suffocating for all air-breathing life on earth. Therefore the 21% figure for oxygen is an optimum value, planned for our well being. |
