Expert Answer
Ozone (O3) is composed of three atoms of Oxygen. Environmental scientists classify ozone into Good ozone and Bad ozone.
Good ozone is present in the upper Stratosphere. It is called so because it protects living beings from the harmful UV rays of the Sun.
Bad Ozone is found in the troposphere or at ground level. This gas does not exist naturally but is formed when hydrocarbons and Nitrogen oxide react with each other in the presence of sunlight. It contaminates the air and results in the formation of smog or haze.
