Fact sheet on air
What?
Air contains 78 percent nitrogen and 21 percent oxygen. The remaining one percent comprises the noble gas argon, and carbon dioxide.
_____________________________
From where?
With the help of sunlight Cyanobacteria produced the first oxygen 2.5 billion years ago using the large quantities of CO2 available in the earth's early atmosphere.
_____________________________
How high?
The atmosphere ends at a height of 100 kilometers, which is where space officially _____________________________
begins. But life can only be found up to heights of 10 kilometers.
_____________________________
How much?
Some 5,000 trillion tons. That's a figure with 21 zeros! Three quarters of that mass can be found in an 11 kilometer-wide radius around the earth. That's because air density decreases with height.
_____________________________
How surprising!
Today, almost a fifth of the air is made up of oxygen. Seventy million years ago, it was more than a third!
