Learn about the causes and effects of ozone depletion. This is a school project on the ozone layer made by my daughter aakanksha. Ozone (o3) is a stratospheric layer that plays important role in providing support to humans for their survival it is an essential factor for many global, biological and environmental phenomena the ultra-violet (uv) rays emitted from sun are captured by ozone and thereby provide a stable. 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 what is it. The ozone (o3) filters about 99% of ultraviolet radiation reaching us from the sun and necessary for the life on the earth.
The ozone layer is important because it filters harmful ultraviolet radiation as it travels from the sun to the surface of the earth these ultraviolet rays can harm both plant and animal life after observation of a depletion of the ozone layer from the addition of chlorofluorocarbons and other man. Depletion of the ozone layer causes of ozone layer depletion effects of ozone layer depletion ozone layer depletion facts. 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 sun renews the ozone and natural chemicals in our atmosphere destroy it. Ozone depletion: ozone depletion, gradual thinning of earth's ozone layer caused by the release of chemical compounds containing gaseous chlorine or bromine from industry and other human activities the thinning is most pronounced in the polar regions, especially over antarctica. Ozone layer depletion and its harmful effects - just watch it | powerpoint ppt presentation overpopulation - ozone layer depletion ozone function: block uv radiation from sun problems: 1) cfcs destroying ozone molecules in atmosphere 2. Know about ozone layer depletion causes, effects and solutions to save this layer is explained here.
Ozone and uv: where are we now the stratospheric ozone layer absorbs most of the harmful ultraviolet b (uvb) radiation (shortwave uv rays measuring 280-315 nanometers, or nm) emitted by the sun because of ozone depletion. Read about the importance, preparation, structure, and properties of the ozone layer understand the reasons for ozone layer depletion and how it can be counteracted. Ozone depletion is a crucial environmental problem on earth the growing concern over cfc production and the hole in the ozone layer is causing alarm among scientists and citizens. The evolution of ozone layer depletion, its impact on climate change, health and the environment.
This presentation gives a brief knowledge of what is a ozone layer , where is ozone layer, its importance and how and why it is depleting.
Ozone layer depletion1 2 3 why the hole in the atmospheric ozone layer above us what has been done about this why should i w. Kids learn about the depletion of the ozone layer how cfcs have cause a hole in the ozone for teachers and students. On this day of september 16, marked as the ozone layer day, let use try to know some of the basics of ozone layer like what it is, its importance, how it gets depleted, effects of its depletion, how to prevent depletion of ozone layer, montreal protocol, our role in preventing ozone layer etc. Ozone gas, formation of the layer, location, role and smog the information you provide through this survey is collected under the authority of the department of employment and social development act (desda) for the purpose of measuring the performance of canadaca and continually improving the.
How ozone depletion affects uv levels depletion of the ozone layer has consequences on humans, animals and plants this typically results from higher uv levels reaching us on earth. Efforts to heal the hole in earth's ozone layer over antarctica appear to be paying off, according to a new, first-of-its-kind study. 1 the ozone layer serves as an umbrella or protective shield of the troposphere and saves the earth's surface from most of the ultraviolet solar radiation by absorbing ultra-violet rays as results of ozone depletion, the increased ultraviolet solar radiation in turn would raise the. Ozone depletion and climate change as lay people feared a depletion of the ozone layer (ozone shield) risked increasing severe consequences such skin cancer, cataracts, damage to plants, and reduction of plankton populations in the ocean's photic zone. Ozone layer depletion - causes, effects and solutions ozone layer depletion is one of the most serious problems faced by our planet earth it is also one of the prime reasons which are leading to global warming ozone is a colourless gas which is found in the stratosphere of our upper atmosphere.
