This picture shows the total volume of air and water (formed into spheres) on Earth compared to the size of the Earth.

Global water and air volume.
Conceptual computer artwork of the total volume of water on Earth (left) and of air in the Earth's atmosphere (right) shown as spheres (blue and
pink). The spheres show how finite water and air supplies are. The water sphere measures 1390 kilometres across and has a volume of 1.4
billion cubic kilometres.
This includes all the water in the oceans, seas, ice caps, lakes and rivers as well as ground water, and that in the
atmosphere. The air sphere measures 1999 kilometres across and weighs 5140 trillion tonnes. As the atmosphere extends from Earth it becomes less
dense.
Half of the air lies within the first 5 kilometres of the atmosphere.
Kind of shocked me to see this comparison, I would have thought that there was more air and water than what this shows.
Makes you realize why we must conserve and protect our resources and the environment.
