Introduction
We live on a marvelous, beautiful planet and there is no doubt that every day we wake up we have air to breathe and we have water to drink and food to eat, but how does our atmosphere play a part in all of this. We also need to question the things people are saying that somehow don't make sense whatsoever.
Seeing Beyond the Horizon
The atmosphere is comprised of Nitrogen (78%), Oxygen (20%), Water Vapor (1%), Argon (.91%), Carbon Dioxide (.0388%), and a sprinkling of other gases. The oxygen which allows us to breathe, water vapor, and carbon dioxide, are the most essential gases to life.
Oxygen and carbon dioxide keep each other stable in a two-end carbon cycle. This starts off with plants which absorb carbon dioxide, water, and the Sun's energy. With these ingredients plants can conduct photosynthesis, which is a chemical reaction that yields glucose, and oxygen. The oxygen from the plants gives our atmosphere oxygen, now what gives the plants their carbon dioxide and water vapor? And what is glucose?
In the second half of the cycle animals and other oxygen breathing organisms come into play. The animals burn glucose (a fuel for your body, like gasoline is fuel to a car) along with oxygen, this reaction yields carbon dioxide and water vapor. The carbon dioxide is exhaled from your body as an emission because you can't burn exhaust. The water vapor evaporates and condenses with the clouds in our atmosphere.
The Nitrogen in our atmosphere keeps the oxygen present in our atmosphere from exploding, for oxygen is a very flammable gas.
Where Everything Is?
Each gas that comprises our atmosphere has a certain density that will determine its level in our atmosphere, whether it will be present in the troposphere, stratosphere, mesosphere, or thermosphere.
Since each gas in the atmosphere has a certain density it will be found only at a certain range of levels in the atmosphere. Oxygen and nitrogen are the two gases that make up most of our atmosphere; the density of oxygen is 1.429 g/L, and composes 20% of the atmosphere, and nitrogen has a density of 1.251 g/L, and makes up 78% of the atmosphere. If we do the math this results in an average density of 1.26g/L for the majority of the atmosphere. Carbon dioxide has a density of 1.89 g/L, therefore it will be present lower in the atmosphere because it has a higher density. The theory of global warming contradicts the laws of physics when it in it suggests that carbon dioxide is high up in our atmosphere.
