Which of the Following Are Reasons of Ozone Depletion

Reactions explaining how ozone depletion occurs. Cause effects and solutions on Business Standard.

Ozone Layer Depletion Causes Affecting Factors Ozone Hole Etc Ozone Layer Ozone Depletion Ozone

The main effect of ozone depletion is an increase in UV-B rays reaching the earths surface.

. The ozone layer depletion is also caused due to some natural processes such as stratospheric winds and. NATURAL CAUSES OF OZONE LAYER DEPLETION Ozone layer has been found to be affected by certain natural phenomena such as Sun-spots and stratospheric winds. O3 UV --- O2 O.

Technological Technical Criteria. Which disease is caused in human beings. Natural decomposition of ozone.

For example chlorofluorocarbons CFCs once used in almost all refrigeration and air conditioning systems eventually reach the stratosphere where they are broken apart to release ozone-depleting chlorine atoms. CF 2 Cl 2 UV light CF 2 Cl Cl. CFCs generally dont react but only react with sunlight when it breaks down to release chlorine.

ODS include chlorofluorocarbons CFCs hydrochlorofluorocarbons HCFCs halons methyl bromide carbon tetrachloride hydrobromofluorocarbons chlorobromomethane and methyl chloroform. Human activity is the major factor in tipping that natural balance mostly from releasing artificial chemicals known as ozone-depleting substances ODS to the atmosphere. Causes of Ozone Layer Depletion.

Stratospheric chlorine is at present the major catalyst of ozone depletion. 65 rows ODS A compound that contributes to stratospheric ozone depletion. Ozone depletion occurs when the natural balance between the production and destruction of ozone in the stratosphere is tipped in favor of destruction.

These chemicals are widely known as ODS an acronym for Ozone-Depleting Substances. CFC reacts with ozone layer and it results in the depletion of ozone layer. The correct option is C CFC.

Chlorofluorocarbon CFCs halons and other compounds deplete the ozone layer. There is more than sufficient evidence for significant CFC-caused ozone depletion. The main causes of ozone depletion or formation of ozone hole are manufactured chemicals especially halocarbon refrigerants solvents propellants and foam-blowing agents chlorofluorocarbons CFCs HCFCs halons referred to as ozone-depleting substances ODS.

Since this area is considered a little more contriversial I have referenced it more heavily. CFCs are the main reason for the Ozone hole or depletion of the Ozone layer. On World Ozone Day have a look at the various causes effects and solutions of.

The simultaneous rise of CFCs and free chlorine in the stratosphere coupled with a corresponding decrease in ozone have been. Ozone depletion is primarily caused by human activities. It is also believed that the major volcanic eruptions has also.

Read more about Ozone layer depletion. Decomposition of ozone by free chlorine atom. Large amounts of lab evidence prove a number of pathways by which chlorine and bromine destroy ozone in carefully simulated stratospheric conditions.

Ozone layer depletion is a phenomenon not directly cognizable which is difficult to be simulated inside an educational laboratory. CFCs are generally composed of carbon fluorine and chlorine. Chlorofluorocarbon CFC is an organic compound that contains only carbon chlorine and fluorine.

Personally I have found very little disagreement among atmospheric researchers on major causes of Ozone depletion particularly the role of man-made chlorofluorocarbons in the depletion. These compounds release chlorine and bromine on exposure to high ultraviolet light which. Ozone depletion is a major environmental problem because it.

In the stratosphere the region of the atmosphere between about 6 and 30 miles 10 and 50 kilometers above the Earths surface ozone O3 plays a vital role by absorbing harmful ultraviolet radiation from the sunStratospheric ozone is threatened by some of the human-made gases that have been released into the atmosphere including those known as. Credible scientific studies have substantiated that the cause of ozone layer depletion is human activity specifically human-made chemicals that contain chlorine or bromine. This decrease has been linked to synthetic chemicals like chlorofluorocarbons CFCs which are used as refrigerants and in fire extinguishers.

The other reasons for ozone depletion are a wide range of industrial and consumer applications mainly refrigerators air conditioners hydrochlorofluorocarbons HCFCs and fire extinguishers. What are the causes and effects of ozone depletion. This radiation release chlorine atoms react with the ozone layer and cause depletion.

This compound does not get degraded by any biological process. They are quite durable and can sustain harsh conditions. The main cause of ozone depletion and the ozone hole is man-made chemicals especially man-made halocarbonrefrigerants solvents proplellants and foam-blowing agents chlorofluorocarbon CFCs HCFCs halons referred to as ozone-depleting substances ODS.

The government bans those products which contain CFCs. Up to 24 cash back These chemicals break apart when they reach the stratosphere and release chlorine atoms that react with ozone and start the destruction that depletes the ozone layer. These compounds are transported into the stratosphere.

CFCs are man made chemicals that are very stable in the atmosphere. The nitrogenous compounds are also the reason behind the depletion of the ozone layer such as NO NO2 and N2O. It is the depletion in ozone molecules as chlorine and bromine atoms come.

ChloroflourocarbonsCFC are the big dog as far as causes of ozone depletion are concerned. But this has been found to cause not more than 1-2 depletion of the ozone layer and the effects are also thought to be only temporary. The amount of ozone in the atmosphere began to drop sharply in the 1980s.

These gases bring chlorine and bromine to the stratosphere which cause depletion of the ozone layer. One of the major causes of ozone layer depletion is the chemical chlorofluorocarbons or CFCs. Finally the teaching of ozone layer depletion can break the boundaries of science courses as it demands an interdisciplinary approach based in physics chemistry and biology.

Ozone depletion gradual thinning of Earths ozone layer in the upper atmosphere caused by the release of chemical compounds containing gaseous chlorine or bromine from industry and other human activities see also Air PollutionThe thinning is most pronounced in the polar regions especially over Antarctica.
