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 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.
Layer of earths atmosphere with no outer limits?
The Stratosphere
What is the middle layer of earths atmosphere?
OZONE Layer
Is all the radiation absorbed in the earths atmosphere absorbed in the stratosphere?
true
What is the atmospheric layers in order from farthest away from the earths surface to the closest to the earths surface?
exosphere,thermosphere, mesosphere, stratosphere, troposphere
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 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 is the earths second layer of earths atmosphere?
STRATOSPHERE
What is the strongest evidence that cfcs are in the stratosphere?
Satellite measurements of light passing through the atmosphere
Cfcs break down in the stratosphere under the influence of?
Light , release Cl which damages ozone .
What will be the effect on radiation received at earths surface of a decrease of ozone in the stratosphere?
Decrease of ozone in the stratosphere could cause UV to enter the surface. These could cause skin cancer and the immune system to weak.
Which earths atmosphere is below the stratopause?
The Stratosphere
In which layer of the atmosphere can you find the earths weather?
Stratosphere
Layer of earths atmosphere with no outer limits?
The Stratosphere
What is the effect of ozone layer on stratosphere?
Ozone layer is present in stratosphere. It does not cause it any effect.
