the source of cfc is mainly from refrigerators n ac's...increase in the emission of cfc may lead to a hole in the ozone layer,the result of which is harmful rays such as ultra violet rays reaching out to people which causes skin cancer

What substitutes for CFCs came into being after scientists discovered that CFCs were harming the atmosphere?
Replacements for CFCs (dependding on use) included:HCFCsNitrogenAirPropane
How do human activities contribute CFC's to the atmosphere?
humans use products containing CFCs which accumulate in the atmosphere.
How do you CFCs illustrate that technical knowledge can be a double edged sword?
1. CFCs help in refrigeration but destroy the ozone layer when released into the atmosphere
What are 3 sources of the CFCs that destroy ozone molecules?
3 sources of CFC's are:Aerosol SpraysRefrigeratorsAir conditioners.
What is the strongest evidence that cfcs are in the stratosphere?
Satellite measurements of light passing through the atmosphere

How are cfcs released?
CFCs or chlorofluorocarbons are released when a device that holds it is leaking. Also some aerosols release CFCs into the atmosphere.
What is the protective layer of the atmosphere destroyed by CFCs?
ozone
What percent of the sources of chlorine in the stratosphere are CFCS?
The answer is 69 %
What kind of effect do CFCs - chlorofluorocarbons - have on the atmosphere?
CFCs (chlorofluorocarbons) destroy the ozone layer allowing harmful radiation to reach the earth.
How do human activities contribute CFC's to the atmosphere?
humans use products containing CFCs which accumulate in the atmosphere.
Humans have greatly increased the level of what in the atmosphere?
carbon dioxide

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.
How are cfcs in the upper atmosphere related to the ozone layer?
They are carried by westerlies. They destroy the ozone.
What is the strongest evidence that cfcs are in the stratosphere?
Satellite measurements of light passing through the atmosphere
