The earth's atmosphere is divided into several layers, and each layer plays an important role. The first region extending about 10km upwards from the earth's surface is called the troposphere.
  A: Ozone is an allotrope of oxygen, with three oxygen atoms in a molecule. It is a very powerful oxidizer, and absorbs UV-B and some infrared light. Ozone is unstable and decays on its own, the decay rate being a function of temperature and time. Other compounds can accelerate ozone's decay.Ozone is formed in the troposphere (where we are) by combustion and industrial processes, and by light activating combustion products. This ozone is a component of smog. Ozone is formed in the ozone layer when oxygen molecules are shattered by absorbing UV-C from the Sun.UV-C only penetrates to about the lower stratosphere (above where aircraft fly), and this is where the ozone layer is found.
