What is the strongest evidence that CFC are in the stratosphere?
Satellite measurements of light passing through the atmosphere
What depletes ozone in stratosphere?
The depletion of ozone in stratosphere is due to the continues usage of CFCs. These cfc contribute to the depletion of ozone molecules.
What makes it possible for CFCs to travel up to the ozone layer and destroy ozone?
CFCs are swirled around the world by the global winds. This can take up to ten years for them to reach the lower stratosphere but when there they are still effective at destroying ozone. CFCs in fact have a lifespan in the atmosphere of between 50 and 75 years.
Can rain demolish CFCs?
CFCs are neither soluble in water or reactive with it. Rain has no impact on CFCs
True or false a main cause of the thinning of the ozone layer is global warming?
False. The main cause of the thinning of the ozone layer is the presence of halogen atoms in the stratosphere from man-madeHalocarbon refrigerants (CFCs, freons, halons).
What is the strongest evidence that CFC's are in the stratosphere?
Satellite measurements of light passing through the atmosphere

What reduction is caused by CFCs in the stratosphere?
clouds
What percent of the sources of chlorine in the stratosphere are CFCS?
The answer is 69 %
What layer of the atmosphere is most affected by fluorocarbons?
The ozone layer, which is part of the stratosphere, is the most affected by fluorocarbons. When chlorofluorocarbons or CFCs are released into the atmosphere, they migrate from the troposphere to the stratosphere after about 3 to 5 years. These CFCs destroy the ozone layer.
Where is wind strongest?
in the stratosphere

The depletion of ozone in stratosphere is due to the continues usage of CFCs. These cfc contribute to the depletion of ozone molecules.
Cfcs break down in the stratosphere under the influence of?
Light , release Cl which damages ozone .

What effect do CFCs have on the Earth's stratosphere?
CFCs (Chlorofluorocarbons)What type of substance is it?CFCs are a class of man-made chemicals, generally non-toxic, non-flammable, chemically unreactive, colourless liquids or gases that evaporate easily. They are a group of ozone depleting substances. They damage the Earth's ozone layer, which protects the earth's surface from harmful ultra-violet radiation. CFCs are also powerful greenhouse gases which contribute to global warming.How is it released?Release to the atmosphere is primarily from CFC-containing aerosols, refrigeration equipment and some foams. There are no natural sources of CFCs.
What causes chlorofluorocarbons?
Chlorofluorocarbons (CFCs) are synthetic compounds created as a byproduct of industrial processes, such as refrigeration, air conditioning, and aerosol propellants. They are made up of chlorine, fluorine, and carbon atoms, which make them particularly harmful to the ozone layer.
Why the ozone produced at ground level in large urban environments does not simply make its way to the stratosphere to replace the ozone that has been destroyed by CFCs?
Ozone at ground level is pollutant. It is bound by gravity.
