How does freon destroy the ozone layer? How does climate change affect the lithosphere? How severe is the depletion of the Antarctic ozone layer? How does climate change affect the atmosphere? When will the ozone layer recover? How has Earth's atmospheric composition changed over time?
In 1974, modelling first pointed to increasing levels of chlorofluorocarbons (CFCs, which were often used in aerosol spray cans, foams and cooling devices) as a source of chlorine radicals in the stratosphere that could catalytically destroy ozone5. The dramatic discovery in the mid-1980s of the...

Thinning Ozone Layer– Air pollutants like chlorofluorocarbons (CFCs) have been known to destroy parts of the ozone layer. Located in the stratospheric layer of the atmosphere is the ozone layer. The stratosphere shields the planet from the ultraviolet radiation from the sun. Ultraviolet radiation ha...
formation of polar stratospheric clouds created an environment where chlorine compounds from CFCs could become highly reactive. When sunlight returned to the region in early spring, these reactive chlorine molecules rapidly broke down ozone, leading to the dramatic thinning ...
1) How do CFCs play a role in ozone depletion? Explain and include an equation to demonstrate your answer 2) What are the health effects of ozone in polluted air? Identify at least two pollutants that destroy the ozone layer. Discuss the origination o...
However, as our ozone layer depletes due to use of chlorofluorocarbons (CFCs), UV levels are increasing. This can lead to health effects like skin cancer [source: EPA]. X-rays: X-rays are very high-energy light waves. We're most familiar with their use in a doctor's office, but X...
Let us dig deep into what is ozone layer, how it is formed, causes and effects of ozone depletion and measures to prevent it. Ozone layer is a most important layer for the existence of the earth.Scientists have explored variations and its depletion in la
Hundreds of thousands of tons of CFCS have been left in the higher sky in the last decade which has led to the ozone layer leak above the South Pole that covers an area of that of the United States. Million tons of fuel containing nitrogen and sulphur have been consumed per year, which...
