Figure 1: The Earth’s atmosphere is a relatively thin and fragile layer of gases- a. an artist’s depiction, b. a satellite image: the thin blue band of gas seen here hovering above the surface of the earth is our fragile atmosphere. Within this band, which is only 50km thick, occur 99.8% of the molecules of gas that support and protect all forms of live on earth. [fn][[nid:1079]][/fn]
