Definition of ozone for English Language Learners. : 1  a form of oxygen that is found in a layer high in the earth's atmosphere. : 2  fresh healthy air especially near the sea.
Ozone is a form of oxygen, the molecule contains three oxygen atoms and has the same chemical structure whether it is found high in the atmosphere or at ground-level. Ozone is unstable and will readily combine with other atoms. High in the atmosphere stratosphere ozone is present, and protects against ultraviolet radiation. In contrast to the good ozone in the stratosphere, ozone can present a problem at certain concentrations at ground-level. It is generated both from certain types of pollution and natural sources, including when atmospheric conditions cause stratospheric ozone down toward the earth's surface.
