Atmosphere

Breathing Room

Take a breath! You've got a piece of the atmosphere in your lungs. We breathe about 20 times a minute. Our lives and the lives of most living things depend on the atmosphere that encircles the earth.

Our atmosphere is just the right pressure and makeup for supporting life. Nitrogen gas accounts for most of the air. One-fifth of the air is oxygen, upon which all life depends. There is a small amount of carbon dioxide (0.03%).

Changes in the amount of carbon dioxide and several other gases can affect the temperature of the planet's surface. Vehicles, factories, and volcanoes are some of the major producers of carbon dioxide. An increase in these gases might one day lead to global warming.
