What is air made of?
More than 99% of air is made of three gases: nitrogen, oxygen, and argon. Air contains other gases in very small quantities, including gaseous water, which is called water vapor. Air also contains solids and liquids. Solids in air include pollen, dust, and soot.

How many elements are in the air?
Different Elements That Make Up Air The molecules of two different elements, nitrogen and oxygen, make up about 99 percent of the air. The rest includes small amounts of argon and carbon dioxide. (Other gases such as neon, helium, and methane are present in trace amounts.) Oxygen is the life-giving element in the air.

Is the air made of carbon?
What’s in the Air? By volume, the dry air in Earth’s atmosphere is about 78.08 percent nitrogen, 20.95 percent oxygen, and 0.93 percent argon. A brew of trace gases accounts for the other approximately 0.04 percent, including the greenhouse gases carbon dioxide, methane, nitrous oxide and ozone.

How air is created?
As Earth cooled, an atmosphere formed mainly from gases spewed from volcanoes. It included hydrogen sulfide, methane, and ten to 200 times as much carbon dioxide as today’s atmosphere. After about half a billion years, Earth’s surface cooled and solidified enough for water to collect on it.
