Interesting factors about air

• In addition to oxygen, the air you breathe consists of lots of other gases.
• Just about 21% of the air is made up of oxygen.
• About 78% of the air you intake consists of nitrogen gases.
• Small quantities of other gases, such as methane, argon and carbon dioxide, are also present.
• On Earth in the absence of oxygen, animals and plants can not survive.
• Although air is mostly gas, it contains tonnes of small particles as well. These atmospheric particles are termed as aerosols.
• When the wind blows certain aerosols including dust & pollen are taken naturally. But the air from power plants, car exhaust can also hold smoke, soot & other particles. Those were key contributors to the pollution of the air.
• In addition to sunlight, plants use carbon dioxide gas to generate food and oxygen too. The process is known as photosynthesis.
• The air in our environment is the insulation that prevents the Planet from being too hot or too cold.
• A kind of gas in the air namely ozone safeguards us from many radiations as well.
• The air in the atmosphere will protect us from meteoroids. They rub against the air as meteoroids enter our environment, and are also burned into tiny pieces once they reach Earth.
