World Ozone Day 16 September 2021

🤔 How it works ……..

How Ozone Layer is Depleting

“Ozone layer depletion is the gradual thinning of the earth’s ozone layer in the upper atmosphere caused due to the release of chemical compounds containing gaseous bromine or chlorine from industries or other human activities.”

Causes of Ozone Layer Depletion : The ozone layer depletion is a major concern and is associated with a number of factors.

Chlorofluorocarbons or CFCs are the main cause of ozone layer depletion. These are released by solvents, spray aerosols, refrigerators, air-conditioners, etc.

The molecules of chlorofluorocarbons in the stratosphere are broken down by the ultraviolet radiations and release chlorine atoms. These atoms react with ozone and destroy it.

Unregulated Rocket Launches
Researches say that the unregulated launching of rockets result in much more depletion of ozone layer than the CFCs do. If not controlled, this might result in a huge loss of the ozone layer by the year 2050.

IMPORTANCE OF THE DAY
==========================
16 September – World Ozone Day

On this day in 1987, the Montreal Protocol was signed. Since 1994, World Ozone Day is celebrated which was established by the United Nations General Assembly. This day reminds people about the depletion of the Ozone Layer and to find solutions to preserve it.

😳Why❓❓❓

Why the danger signals are red in colour?

Because the red colour is scattered the least by air, water or dust molecules. So, red light is used as a danger signal as it is able to travel the longest distance through the fog, rain, etc. without being scattered or faded away.

colour which will be visible from a very far way so that any mishap can be avoided. The colour which is used must not fade away with distance.

💁🏻‍♂️ GK TODAY

The ozone layer is the common term for the high concentration of ozone that is found in the stratosphere around 15–30km above the earth’s surface. It covers the entire planet and protects life on earth by absorbing harmful ultraviolet-B (UV-B) radiation from the sun.

Ozone is a molecule made up of three oxygen atoms, often referenced as O3. Ozone is formed when heat and sunlight cause chemical reactions between oxides of nitrogen (NOX ) and Volatile Organic Compounds (VOC), which are also known as Hydrocarbons.

IDIOMS & PHRASES : BOIL THE OCEAN:
Taking up an almost impossible or overly ambitious project

Did you know ?
Rice water is also good for acne since it reduce redness and clear blemishes, and the starch in the water is said to soothe the inflammation of eczema.

Rice contains natural antioxidants like vitamin C, vitamin-A, phenolic and flavonoid compounds, which may minimize free radical damage from age, sun and environment.
