17 Δεκ 2016 · Air is a mixture of gases that forms the Earth's atmosphere. It is composed primarily of nitrogen (78%) and oxygen (21%), with trace amounts of other gases like carbon dioxide and water vapor. Air is essential for supporting life on Earth, as oxygen allows for burning and respiration to occur.
