Ozone is a gas that occurs both in the Earth's upper atmosphere and at ground level. Ozone can be good or bad for your health and the environment, depending on its location in the atmosphere.
Ozone is a natural gas composed of three atoms of oxygen. It chemical symbol is O3. It is blue in color and has a strong odor. Normal oxygen (O2), which we breathe, has two oxygen atoms and is colorless and odorless.Environmental scientists have classified O3 into two: Good Ozone and Bad Ozone. Good Ozone.ven though Ozone is only a small part of the gases in this layer, it plays a vital role because it shields us from the sun's harmful UV rays. It is called Good Ozone, for obvious reasonsâbecause it protects humans, life and animals on earth.
