Ozone layer – Description


We rarely need to imagine the situation in the summers when the temperature crosses 45-degree mark and makes life miserable. Heat strokes in the certain part of India cause many deaths and skin related diseases see multifold increases. When 45° to 50° degree temperature takes the life out of us humans and other living beings; What if the temperature on the Earth touches the range of 5,227 to 5,727 °C.

Well, that is the actual radiation the Sun emanates on a daily basis to the Earth. Then what makes the survival possible for living being on the Earth? Ozone Layer.

What is Ozone Layer?

Two French physicists discover in the year 1913 that Sun sends out the radiation around 5000 °C when it reaches the Earth, which can make life non-existential on the Earth. Charles Fabry and Henri Buisson established the fact that there is something that absorbs almost all the mid-range radiation of the Sun but failed to find out the exact element that absorbs the ultraviolet rays coming from the Sun.

G.M.B Dobson, during his research, established the fact that the element that absorbs almost 97 to 99% of the Sun’s radiation is Ozone. He developed a Dobsonmeter to measure the effectiveness of the Ozone layer from the ground. In his research, he established that the missing radiation that supposed to reach to the Earth matches that of the chemical known as Ozone, which covers the entire Earth and protects human life from the fury of the Sun.

The Distribution of the Ozone Layer

The thickness of the thinness of the Ozone layer is not consistent and is mainly dependent on the greenhouse gases as well the season. In its usual form, the Ozone layer is thin around The Equator and thick near the poles. During the summers you can measure Ozone layer being thin, while in the winters, it is thick. Besides, solar intensity plays the critical role in deciding the effectiveness of the Ozone Layer.

The Ozone Structure

Science sometimes throws unimaginable surprises. Ozone is a structure that is nothing less than an ultraviolet layer similar to the Sun’s UV rays, which is made of the Oxygen only. While the water consists of two Oxygen atoms, Ozone is made of the three Oxygen atoms.

Why Ozone Layer?

Thinking of life on the Earth at the temperature of 5000 °C is an unthinkable thing. This fact itself explains the importance of Ozone layer. Radiation coming out of the Sun would not only destroy the plants and trees but would also kill the living beings from the Earth. Besides, if all the ice will melt in a day or two with such a high temperature, life on the Earth can never be possible. Even a one percent decrease in Ozone could affect the life severely on the Earth. Therefore, we must ensure that we do not eliminate the harmful gases and preserve the environment as much as we should.
