The ozone layer is responsible for absorbing harmful ultraviolet rays, and preventing them from entering the earth's atmosphere however, various factors have led to the depletion and damage of this protective layer learn more about the process, causes, and effects of ozone layer depletion. The latest ozone layer depletion news is included at the foot of the page depletion of the ozone layer: the wearing out or destruction of the ozone in the stratosphere the ozone layer is a belt of the naturally-occuring gas 'ozone' that sits at an altitude of between 15 and 30 kilometers above the earth. The ozone layer is a belt of the naturally occurring gas ozone it sits 93 to 186 miles (15 to 30 kilometers) above earth, and serves as a shield from the harmful ultraviolet b (uvb) radiation. Natural causes of depletion of ozone layer: ozone layer has been found to be affected by certain natural phenomena such as sun-spots and stratospheric winds 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.
Causes of ozone layer depletion the primary reason behind the reduction of the ozone layer is the use of hydro- chloro-fluoro-carbons (hcfcs) and chloro-fluoro-carbons ( cfcs) they are compounds of chlorine, fluorine, and carbon such as cf 3 cl, chcl 2 f etc. This website addresses stratospheric ozone issues, including the science of ozone depletion, epa's regulatory approach to protecting the ozone layer, epa-approved alternatives to ozone-depleting substances, and sun safety. Chlorofluorocarbons (cfcs) have been found to cause the depletion of the ozone layer the ozone layer prevents ultraviolet radiations of the sun from coming on the earth this article describes the process of damaging effects of cfcs.
The easy answer is ozone layer protects us from ultraviolet light but what you never hear ultraviolet reacts with oxygen and creates ozone ozone neutralizes vocs and kills mold germs bacteria and viruses all of which can lower your immune sys. What is the ozone hole a decrease in 1% of ozone layer can cause 5% increase in cases of skin cancer depletion of ozone layer and increase in uv rays can also cause dna damage which can also be catastrophic aquatic plants and animals are not even safe uv rays can penetrate through water and can kill small plants and animals. The causes, mechanism and bio-effects of ozone layer depletion on humans were addressed it is revealed that introduction of chlorof-lourocarbons (cfcs) in the environment is the most rated cause.
In 1985, joe farman, brian gardiner, and jon shanklin discovered depletion of the ozone layer over antarctica by as much as 70% in austral spring scientists suddenly realized that ozone depletion was a much bigger problem than had been thought. Ozone depletion occurs when the natural balance between the production and destruction of stratospheric ozone is tipped in favour of destruction although natural phenomena can cause temporary ozone loss, chlorine and bromine released from man-made compounds such as cfcs are now accepted as the main cause of this depletion. Ozone depletion is a major cause of concern for the entire world the main factor responsible for causing the depletion of the ozone layer is an increase in the levels of free chlorine and bromine in the upper atmosphere of the earth. The connection between ozone layer depletion and uvb radiation reduced ozone levels as a result of ozone depletion ozone depletiona chemical destruction of the stratospheric ozone layer beyond natural reactions stratospheric ozone is constantly being created and destroyed through natural cycles.
The layer of ozone helps prevents the harmful ultraviolet rays away from entering the earth’s atmosphere ozone layer depletion over the years has resulted in ozone hole formation through which harmful radiations can now enter the atmosphere. Ozone layer depletion facts ozone is a form of naturally occurring gas – and 90% of our planet’s ozone is in the stratosphere it is constantly being renewed and destroyed. The ozone layer is a layer of ozone gas (o3) in the stratosphere of the earth’s atmosphere that lies around 10 to 30 miles (16 to 48 kilometers) over the surface of the earth ozone (o3) resembles general gaseous oxygen (o3) with an additional oxygen molecule appended to it.
Ozone depletion describes the observed loss of ozone in the stratosphere over the past 50 years it encompasses both a steady thinning of the ozone layer at mid-latitudes and its catastrophic. Causative agents of ozone layer depletion some of the humans’ activities are the prime cause of depletion of ozone layer due to industrialization and rapid technological advancements, the amount of greenhouse gases has been exponentially increasing.
Causes of ozone depletion in the stratosphere studies have argued that the influence of 7,500 tons of chlorine from cfc amounting annually to the stratosphere is minimal compared to 600 million tons of chlorine and fluorine (other aggressive gas) like salts escaping oceans as aerosols. Ozone depletion is primarily caused by human activities the main effect of ozone depletion is an increase in uv-b rays reaching the earth's surface causes: chlorofluorocarbon (cfcs), halons, and other compounds deplete the ozone layerthese chemicals are found in cleaning agents, aerosols, insulating foam, and refrigerants. Ozone layer depletion, is simply the wearing out (reduction) of the amount of ozone in the stratosphere unlike pollution, which has many types and causes, ozone depletion has been pinned down to one major human activity.
