Description
Global air volume. Conceptual computer artwork of the total volume of air within the Earth's atmosphere, seen as a sphere, centred over North America. It dramatically shows how finite the available air supply actually is. The sphere measures 1999 kilometres across and weighs 5140 trillion tonnes. Although the atmosphere extends hundreds of kilometres above the Earth's surface, its density decreases progressively. Half of all the air in the atmosphere lies within the first 5 kilometres. Air is a mixture of gases that includes nitrogen (78%) and oxygen (21%). The reminder is made up of argon, carbon dioxide, neon and helium.
