Ozone layer

                                          Ozone layer

Nowadays there are often saying of ozone layer. Because of air pollution, ozone layer is vanishing. Ozone layer found around 25-30 meter from the surface of Earth.
The thickness of ozone layer is measured in Douglas Units. Ozone layer protect us from the bas Infrared Rays (IR rays ) of Sun. As it becomes thin, more IR rays will enter into atmosphere . Exposure to IR rays will result in skin cancer and other health problems for humans.
But how will we know the thickness of Ozone layer? It is much above us and we can not take rulers to measure the thickness of ozone layer. For that reason, special satellite named Neo 7 is there. It will measure the thickness of the layer.
Ozone is the isotope of oxygen. Its chemical formula is O3 means 3 atoms of Oxygen. The emission of CO2(carbon di oxide) due to air pollution is hazardous to the layer.
