Essay On Climate Change
Essay on Ozone Layer is to understand the ozone layer, it might be useful to understand the various layers of the atmosphere. Lots of human activities like gas balloons, climbing, and little craft flights happen in this region. The layer is that the next layer higher than the layer stretching or so fifteen to sixty kilometers. The Essay on Ozone Layer sits within the lower region of the stratosphere from concerning kilometers higher than the surface of the planet. The thickness of the ozone layer is concerning three to five millimeter, however, it just about fluctuates looking on the season and ozone layer essay. This lower region of the layer containing a comparatively higher concentration of ozone is named the ozone layer, ozone layer essay.
The ozone layer is found kilometers nine to twenty-two miles higher than the surface of the world. The concentration of ozone within the ozone layer is sometimes underneath ten components per million whereas the common concentration of ozone within the atmosphere is concerning 0. The thickness of the ozone layer differs as per season and geography. The very best concentrations of ozone occur at altitudes from twenty-six to twenty-eight kilometer ozone layer essay to seventeen miles within the tropics and from twelve to twenty kilometer seven to twelve miles towards the poles, ozone layer essay. The ozone layer forms a thick layer in the stratosphere, ozone layer essay, skirting the planet, that has a great amount of ozone in it.
The ozonosphere protects life on earth from sturdy ultraviolet radiation that comes from the sun. Ultraviolet rays are harmful rays that will approach the danger of deadly disorders like carcinoma, cataracts and harm the system. Ultraviolet rays also are capable of destroying single-cell organisms, terrestrial plants, and aquatic ecosystems. The ozonosphere was discovered in by the French physicists Charles Fabry and Henri Buisson. This method additionally absorbs ultraviolet radiation that is dangerous for many living beings. Ultraviolet radiation may injure or kill life on Earth. analysis scientists have anticipated disruption of inclined terrestrial and aquatic ecosystems because of depletion of ozonosphere.
Ultraviolet radiation may destroy organic matter. Plants and organisms cannot thrive, each acts as food for land and ocean animals, severally. For humans, excessive exposure to UV results in higher risks of cancer especially skin cancer and cataracts. Different ill-effects of the reduction of protecting ozonosphere embrace — increase the incidence of cataracts, sunburns, and suppression of the system Essay on Ozone Layer. It comes as a surprise that equivalent ultraviolet rays form the majority of the ozonosphere. Ozone is a rare reasonably chemical element composed of three oxygen atoms rather than the traditional two oxygen atoms.
Ozonosphere ordinarily develops once a number of varieties of discharge or radiation split the two atoms in an oxygen O2 molecule, which then severally reunites with different forms of molecules to create ozone. People began to worth the importance of the ozonosphere once scientists discharged an inquiry finding suggesting that bound human-made chemicals referred to as chlorofluorocarbons managed to succeed in the layer and depleted the ozone via a profound series of chemical reactions. The results of this analysis study prompted the language of a worldwide pact called the Montreal Protocol in This written agreement helped with the reduction of the assembly of those harmful human-made chemicals.
These targeted efforts have seen the ozonosphere convalescent over the past years. The thickness of the ozonosphere varies vastly on any day and placement. Because of relentless vertical part air circulation in each of the stratosphere and layer, the quantity of ozonosphere shielding humans from sturdy ultraviolet rays is often lesser or larger. Additionally, those residing in higher elevations are in danger of ultraviolet ozone layer essay than those at ozone layer essay elevations. Stratospheric gas plays an enormous role in protecting humans from the harshness of the sun. In some people, it will result in complications in respiratory and infrequently takes place ozone layer essay summer once pollution is rampant in cities wherever the air is static.
Essay on Ozone Layer: Credible scientific studies have supported that the reason for layer depletion is human action, specifically, human-made chemicals that contain chlorine or bromine. These chemicals are widely referred to as ODS, a signifier for Ozone-Depleting Substances, ozone layer essay. The scientists ozone layer essay determined a reduction in stratospheric gas since the early s. Ozone-Depleting Substances are established to be eco-friendly, terribly stable and non-toxic within the atmosphere below. This is often why they need gaining quality over the years. Once up there, ODS is well dampened by the sturdy ultraviolet light and therefore the resultant chemical is chlorine and bromine, ozone layer essay.
Chlorine and bromine are renowned to consume the layer at supersonic speeds. They are doing this by mere removal of an atom from the gas molecule. One chlorine molecule has the potential to interrupt down thousands of ozone molecules. Ozone-depleting substances have kept and can continue to stay within the atmosphere for several years. The chief ozone-depleting substances embrace chlorofluorocarbons CFCsozone layer essay, hydrochlorofluorocarbons HCFCs and methyl radical chloroform. Halons, generally called brominated fluorocarbons, conjointly contribute mightily to ozone depletion, ozone layer essay. Studies suggest that top levels of ultraviolet Rays cause non-melanoma carcinoma and plays a ozone layer essay role in skin cancer development.
Permanent exposure to ultraviolet rays can even cause weakening of the response of the system and even permanent injury to a system in some cases. Aging of the skin ozone layer essay yet one more drawback which will cause you to look older than what you actually are. Intensive exposure to ultraviolet rays will cause the acceleration of the aging method of your skin. EFFECTS ON PLANTS: Plants become another casualty by radiation effects of ultraviolet rays. The physiological and biological process of plants also is severely affected aside from the expansion. Other changes that are caused by ultraviolet include the method plants type, ozone layer essay, temporal order of development and growth, ozone layer essay, however, nutrients are distributing inside the plant and metabolism, ozone layer essay, etc.
It badly affects the planktons that form the inspiration of aquatic food webs. The plant grows near the surface of the water and plays a very important role within the organic phenomenon ozone layer essay oceanic carbon cycle. Changes in ultraviolet levels is recognized to have an effect on each orientation and motility in the plant. This reduces the survival and rate of those organisms. UV rays also are famous to have an effect on the event stages of fish, shrimp, crab, amphibians, and different marine animals. once this happens it affects the whole marine organic phenomenon as animals within the higher organic phenomenon that kills these fishes also are affected. Changes in ultraviolet levels would contribute to biosphere-atmosphere feedbacks that mitigate or amplify the region concentrations of those ozone layer essay. Desist from Using Pesticides: Pesticides are nice chemicals to rid of your farm of pests and weeds, however, they contribute tremendously to ozonosphere depletion.
The surefire resolution to induce eliminate pests and weeds is to use natural ways. Simply weed your farm manually and use different eco-friendly chemicals to alleviate pests. Discourage Driving of Personal Vehicles: The easiest technique to reduce ozone depletion is to limit the number of vehicles on ozone layer essay road. Ozone layer essay vehicles emit plenty of greenhouse gases that eventually form air pollution, a catalyst within the depletion of the ozonosphere. Utilize Environmentally Eco-Friendly Products: Most home improvement merchandise is loaded with harsh chemicals that realize thanks to the atmosphere, ozone layer essay, eventually conducive to degradation of the ozonosphere.
Use natural and environmentally friendly improvement merchandise ozone layer essay arrest this example. Skip to content Essay. ctet 0 Comments. You May Also Like.

Ultraviolet light splits the relatively unstable Omolecules into O and atomic O. Most of the time, the O atom created by Ozonebreakup recombines with one of the plentiful O molecules to re-form O. ThisOzone-creation process is constantly at work producing more ozone. In general, biologists and healthprofessionals recognize that life on earth enveloped under the protection of anozone layer thick enough to remove much of the UV-B solar radiation known todamage cellular organisms. Accordingly, various organisms—including humans—may have difficult adjusting to the higher UV-B levels resulting from a thinnerozone Layer.
Medical studies have quantified some of the expected effects ofincreased UV-B levels, based on real-life information form people exposed togreater than average UV-B levels—populations living at high altitudes and inthe tropics, where the average ozone layer is thinner and the sunlight moredirect. The most serious medical effects include increased incidence ofcataracts and skin cancer, as well as evidence of weakened immune-systemresponse. Ecological research indicated that some crop yields will decrease anddisruption in marine food chains may occur. A weakened ozone layer may also case climatological effects. Thestratosphere warms with altitude because the splitting of stratospheric ozone iscaused by ultraviolet photons, which contain much more energy than that requiredto break the O-O bond.
This extra energy is converted to heat. Ozone can be destroyed by chemicals that react directly with it, or bythose that react with the oxygen atom temporarily freed whenever an o moleculebreaks apart. In the last few years, various human activities have released ozone -destroying chemicals into the atmosphere. Of Particular importance are halogenatoms — chlorine and bromide. Chemicals release into the ozone by industrialparticles include chlorocarbon compounds such as CCL and CHI CL ,chloroflucarbon compounds CFCs and halon compounds. Chlorocarcon compounds are used primarily as industrial solvents,degreasing compounds, and CFC precursors.
The CFCs are used as working fluidsin refrigeration and air conditioning units. Aerosol propellant agents. TheHalons are used as fire suppressants. Once in the stratosphere, all thesechlorine and bromine containing compounds are broken apart by solar ultravioletradiation, releasing their Cl or Br atoms. These atoms start the process ofOzone destruction. Each Chlorine of Bromine atom that starts the destructioncycle can destroy , ozone molecules. There are on the other hand naturalozone depletes such as volcanic eruptions. A hole in the Ozone has emerged because of all of the depletion.
Starting in the spring of , a massive 8. Forthe past 16 years the hole has grown larger. There was a theory that predictedthat the most severe O loss would occur relatively high in the stratosphereabove 30 km. In fact the largestdepletion over Antarctica occurred in the middle range between 13 and 21 km. Atmospheric chlorine and bromine levels are expected to peak around There are currently steps being made to protect the ozone. One suchstep is the Montreal Protocol on substances that harmed the ozone. Ingeneral people are waking up to this serious problem; as well they should. Themore ozone that is destroyed the more UVA rays and UVB rays that reach the earth. It is hypothesized that by the year if depletion continues at the currentrate that no living organism will be able to survive on on earth unless theyare underwater.
Ozone is debatibly the most important thin known man. The survival ofthe human race is really dependent upon the ozone layer. If we keep using thesedangerous chemicals, such as CFC, found in arisol cans, we could ultimatlydestroy the ozone layer. If we destroy the ozone layer then we are reallykillling ourselves. If the ozone layer is destroyed then powerful ultriviolentrays will penitrate the earth and everyone would get skin cancer and eventuallydie. I hope organizations will continue to work to prevent the distruction ofozone because I would like to see man survive for a while. Hi there, would you like to get such an essay?

Cfcs Cause Deterioration Of The Ozone Layer Essay Words 8 Pages. The depletion of ozone comes from chemical emissions, which then react in the stratosphere breaking down ozone. The worst of these chemicals are called halocarbons and include CFC's chlorofluorocarbons but nitrous oxide and methane also deplete ozone. Graedel Here is a graph of the different layers in the atmosphere: Troposphere The troposphere is the atmospheric layer closest to the planet and contains the largest percentage of the mass of the total atmosphere. Garcia It is characterized by the density of its air and an average vertical temperature change of 6 degrees Celsius C per kilometer. Graedel Temperature and water vapor content in the troposphere decrease rapidly with altitude. Water vapor plays a major role in regulating air temperature because it absorbs solar energy and thermal radiation from the planet's surface.
At many kilometers above the earth there is a high level of UV radiation and this lead to photo-dissociating the Oxygen molecules after absorbing ultraviolet photon whose wavelength is shorter than nm. Every oxygen molecule is being dissociated into two free atoms. middle of paper ause ODS work just as catalysts in the process of ozone depletion so they remain in the ozone layer for a long time. Ozone Ozone is an important molecule in maintaining the homeostasis in the environment. Ozone, the molecule O3, makes a layer in the stratosphere, situated 10 to 15 kilometers from the earth's surface. The dioxide molecule, O2 and Oxygen atom O, collide with each other result in the formation of Ozone, O3. In this reaction, the molecule O3 contains an excess of energy.
Once the molecule is formed, it is not stable enough to last long. People should especially avoid going outside during 10 am and 4 pm, as thats when the UV rays are the strongest. Nunas, 8 The ozone layer is depleting due to chlorofluorocarbons, a man made chemical that has other replacements. Due to this depletion, toxic ultraviolet radiation is entering the earth's stratosphere from the sun. UV rays are destroying our plants and the aquatic food chain, as well harming ourselves. UV radiation causes people to be at a higher risk of skin cancer, including malignant melanoma. The tropospheric ozone also plays an important role in the atmosphere. Home Page The Ozone Layer Essay. The Ozone Layer Essay Satisfactory Essays.
Open Document. Essay Sample Check Writing Quality. It contains a high concentration of ozone molecules. If the ozone layer were not present the radiation from the sun would kill most living things and make our planet uninhabitable. The size and thickness of the ozone layer varies by location and the time of year. It is larger towards the poles of the earth and at its thickest during the spring time. The ozone layer was first discovered by Charles Fabry and Henri Buisson in In a network of ozone monitoring stations were established and still operate today. The hole is located in the Southern Hemisphere and during the spring months the ozone layer is reduced an estimated 60 percent from its normal levels.
The current status of the ozone layer is much better than it was is in the past. This is primarily due to the education of the population and government restrictions. By educating the population on what substances we produce damage the ozone layer, the ozone layer has been able to slowly replenish its self. The last scientific asse ompletely heal itself within the next 50 years. As we continue to monitor the status of the ozone layer, we still need to study it as well. Understanding the ozone layer and how it works will aide us in new approaches on how to better take care of this precious shield of the Earth.
As science advances, we will be able to simulate what other variants affect the ozone layer, not just the ones we know are harmful. As new products and chemicals are discovered or made, they need to be tested to gauge what, if any impact they will have on the ozone layer. The Montreal Protocol needs to be an ever evolving agreement. I would suggest an annual meeting with all its participants to re-address the list of banned substances and add new ones as they are discovered. With this knowledge we will be able to ensure that are species as a whole can continue to prosper on this planet.
