It also causes damage to various forms of aquatic larvae and other organisms. Conclusion The Ozone layer is very effective for the earth, which can easily harm to the earth, so it was great thing that all over the world have make the solutions for control the measurement of the ozone layer.
My neighbourhood essay for class 2 world My neighbourhood essay for class 2 world years war essay universalis 4 england winner. It is in this background that the appearance of the ozone hole becomes a matter of great concern. Thus, it is useful in this way.
Ozone concentration differs by about 10 ppm in stratosphere compared to 0. In SeptemberMontreal Protocol was held for control measure of the ozone layer and it was followed by the Kyoto Protocol of Plants are sensitive to UV rays below nm so they are badly affected.
Studies with some plant species have shown almost two-third of them to be susceptible. Some breakdown can be expected to continue because of ODSs used by nations which have not banned them, and because of gases which are already in the stratosphere.
Its concentration is only 10 parts per million parts of air.
In nature O3 is formed in the stratosphere when ultraviolet light strikes an oxygen molecule. It is generated there by the interaction of high energy radiation of the sun on the oxygen in the atmosphere.
In the absence of any other disturbances, O3 settles into a dynamic steady state in which the rate of its formation is equal to the rate of its destruction. It is very useful in saving life from sun radiation.
Depletion of the ozone layer is very dangerous for the earth, because it can affect very harmful hazardous in the atmosphere.
The ultra-violet rays can cause skin cancer. UV-B radiation can be harmful to the skin and is the main cause of sunburn ; excessive exposure can also cause cataracts, immune system suppression, and genetic damage, resulting in problems such as skin cancer.
Control measure of ozone layer There are also the various ways to control measure of Ozone layer, which can save the atmosphere of the earth from depletion.
It is an important chemical species present in the stratosphere. Red line shows surface energy level with 10 percent decrease in ozone Levels of ozone at various altitudes and blocking of different bands of ultraviolet radiation. My neighbourhood essay for class 2 world short note on national food security act summary.
So, if humankind is to continue being able to walk around in the sunshine, then the stability of the ozone layer is essential. It was started for betterment of the earth in all over the world. The prolonged cumulative exposure to UV-B rays causes skin-cancer, basal cell carcinoma, squamous cell carcinoma and malignant melanoma etc.
In spite of being a trace gas, it plays a major role in the maintenance of climate and biology of earth. Since the early seventies, when CFCs came into market, a large quantity has been injected into the atmosphere. It filters out all radiations below A0 UV-B radiations that are biologically harmful, and controls the heat budget of the earth.
This GALEX image of the Cygnus Loop nebula could not have been taken from the surface of the Earth because the ozone layer blocks the ultra-violet radiation emitted by the nebula.
Ozone is also capable of absorbing short wavelength UV radiations releasing oxygen atom. Ozone layer is a protective stratospheric layer, also known as ozone umbrella.
Since then, it has undergone seven revision, which are The plan was held in the London in The plan was held in the Nairobi in The plan was held in the Copenhagen in The plan was held in the Bangkok in The plan was held in the Vienna in The plan was held in the Montreal in The plan was held in the Beijing in The recovering of the ozone layer was expected in as per the International agreement and it was the great believe for control the ozone layer from the earth.
Ozone is formed by photochemical reactions, followed by a three-body reaction: These combine quickly with an oxygen molecule to form ozone. In the northern hemisphere these patterns, known as the Brewer-Dobson circulationmake the ozone layer thickest in the spring and thinnest in the fall.
The reasons for these variations are due to atmospheric circulation patterns and solar intensity. These combine quickly with an oxygen molecule to form ozone. It filters out all radiations below A0 UV-B radiations that are biologically harmful, and controls the heat budget of the earth.
While most of the source gases are of natural origin, others have been introduced in nature by man. If there is a pollution of ozone i. Third body, Such as N, Or 02 The role of third body M is to absorb the excess energy liberated by the above reaction and thereby 03 molecules are stabilized.
Sources[ edit ] The photochemical mechanisms that give rise to the ozone layer were discovered by the British physicist Sydney Chapman in High levels of this ultra-violet radiation are harmful to nearly all forms of life.The ozone layer is one of the most important source of protection that exists on Earth.
It is a region of the stratosphere containing a high concentration of ozone, and it prevents a great amount of ultraviolet and other high-energy radiation from penetrating to the earth's surface.3/5(5).
The Ozone layer or ozone shield is a region of Earth's stratosphere that absorbs most of the Sun's ultraviolet radiation. It contains high concentrations of ozone (O 3) in relation to other parts of the atmosphere, although still small in relation to other gases in the stratosphere.
Here is your essay on ozone layer depletion! Ozone (O 3) is a triatomic form of oxygen. It is found largely in the stratosphere that extends from about 6 km at the poles and 17 km at the equator to about 50 km above the earth’s surface. Essay on Effects of Ozone Layer Depletion.
Article shared by.
The upper layer of the atmosphere surrounded by ozone (15 to 30 Kms) is known as ozonosphere. Ozone layer is a protective stratospheric layer, also known as ozone umbrella.
Ozone is also capable of absorbing short wavelength UV radiations releasing oxygen atom. ADVERTISEMENTS. Short Essay on Ozone Hole Article shared by We know that there is a thick layer (or blanket) of ozone gas in the upper atmosphere which acts as a preventive shield against the harmful ultra-violet rays.
Ozone layer is a protective stratospheric layer, also known as ozone umbrella. Ozone concentration differs by about 10 ppm in stratosphere compared to ppm in troposphere. It acts as a protective shield for the man, animals and plants by filtering out the .Download
