What is Ozone?

Ozone is a colorless gas. Chemically, ozone is very active; it reacts readily with a great many other substances. Near the Earth's surface, those reactions cause rubber to crack, hurt plant life, and damage people's lung tissues. But ozone also absorbs harmful components of sunlight, known as “ultraviolet B”, or “UV-B”. High above the surface, above even the weather systems, a tenuous layer of ozone gas absorbs UV-B, protecting living things below.
