Sep 20, 2016 · This seminar presentation summarizes Ozone layer depletion. It introduces ozone and the ozone layer, how ozone depleting substances like CFCs react with ozone leading to its destruction. The consequences of ozone layer depletion include increased skin cancer and other health issues.
Apr 6, 2014 · The document also explains that chlorofluorocarbons deplete stratospheric ozone, causing seasonal ozone holes over Antarctica, and outlines the health and environmental impacts of ozone layer depletion and how to protect the ozone layer and ourselves from UV radiation.
Mar 7, 2017 · The document discusses the ozone layer, its formation and depletion over time. Some key points: - The ozone layer is found 20-30km above the Earth's surface and absorbs UV radiation. - Depletion is caused mainly by CFCs and halogen gases, which are broken down by UV rays to release chlorine atoms that destroy ozone.
ozone are increasingly being observed in rural areas as well. Stratospheric ozone, in contrast, plays a highly beneficial role. It absorbs most of the sun’s biologically damaging ultraviolet radiation and only allows a small amount to reach the Earth's surface. The ozone layer screens out almost all the harmful
Ozone layer depletion is the thinning of the ozone layer that protects the earth from the harmful UV radiations. Explore the causes, effects, and solutions to ozone layer depletion only at BYJU'S.
The ozone layer keeps about 95% of the sun’s harmful UV radiation from reaching the earth’s surface. Chlorofluorocarbon (CFCs) have lowered the average concentrations of ozone in the...
What caused ozone depletion? By free radical catalysts Emissions from jumbo jets and civil aircraft increased concentrations of chlorine and bromine, nitrogen oxides, and hydrogen liberated by the action of ultraviolet light initiate and catalyze a chain reaction. Slide 6 - How the ozone layer is destroyed?
Nov 6, 2023 · Ozone layer depletion is the decline of the ozone layer in the upper atmosphere. This occurs when ozone molecules come into touch with and are destroyed by atoms of chlorine and bromine found in the atmosphere.
Apr 2, 2020 · Ozone layer depletion means the thinning of the ozone layer present in the upper atmosphere. That is harmful to nature and the atmosphere. Ozone layer depletion is one of the major problems for the atmosphere and also for all the living beings including the flora and fauna of this earth.
5 days ago · The Ozone layer is a layer of oxygen gas with the atoms put together in a special way. It is found about 19-30km up in the stratosphere. The Ozone layer is often in the news because humans are damaging it and we, plants and animals would die without it.
