   ozone
   A molecule made up of three atoms of oxygen. In the statosphere, it occurs naturally and it provides a protective layer shielding the Earth from ultraviolet radiation and subsequent harmful health effects on humans and the environment. In the troposphere, it is a chemical oxidant and major component of photochemical smog.

   Ozone
   A molecule made up of three atoms of oxygen. In the stratosphere, it occurs naturally and provides a protective layer shielding the Earth from ultraviolet radiation and subsequent harmful health effects on humans and the environment. In the troposphere, it is a chemical oxidant and major component of photochemical smog. Ozone is an effective greenhouse gas especially in the middle and upper troposphere and lower stratosphere.

   Ozone
   is a form of oxygen that is produced when atmospheric oxygen is electrically charged. Oxygen is usually found as two atoms together as O2, whereas ozone is when there are three - as O3. It is found at ground level, created from exhaust gases, where it is dangerous and at levels high in the sky where it is protective.

    Ozone
    Allotropic form of oxygen containing three atoms in the molecule. The stratosphere ozone layer, which is a concentration of ozone molecules located at 10 to 50 kilometres above sea level, is in a state of dynamic equilibrium. Oxygen molecules absorb ultraviolet (UV) light to form ozone which, in turn, decomposes back to oxygen. These processes abso...
