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 else can I help you with?
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.
How long does it take for chlorofluorocarbons to reach the stratosphere?
Chlorofluorocarbons, also called CFC, go into the stratosphere. Air is lighter than the CFC and they can take about 2 to 5 years to travel in the stratosphere.
What is the middle layer of earths atmosphere?
OZONE Layer
What is second major layer of earths atmosphere?
The second major layer of Earth's atmosphere is the stratosphere. It extends from about 10 to 50 kilometers above the Earth's surface. The stratosphere is characterized by the presence of the ozone layer, which absorbs much of the Sun's ultraviolet radiation.
The layers of the earths atmosphere from top to bottom are the?
In descending order: exosphere, thermosphere, mesosphere, stratosphere, troposphere.
What reduction is caused by CFCs in the stratosphere?
clouds
What is the earths second layer of earths atmosphere?
STRATOSPHERE
What percent of the sources of chlorine in the stratosphere are CFCS?
Over 80% of the chlorine found in the stratosphere comes from chlorofluorocarbons (CFCs). These compounds can break down in the upper atmosphere, releasing chlorine atoms that can then participate in ozone depletion reactions.
What is the strongest evidence that cfcs are in the stratosphere?
Satellite measurements of light passing through the atmosphere
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
Cfcs break down in the stratosphere under the influence of?
Light , release Cl which damages ozone .
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.
In which layer of the atmosphere can you find the earths weather?
Stratosphere
What is the effect of ozone layer on stratosphere?
Ozone layer is present in stratosphere. It does not cause it any effect.
What depletes ozone in stratosphere?
Chemicals such as chlorofluorocarbons (CFCs) and other ozone-depleting substances released into the atmosphere can break down ozone molecules in the stratosphere. These chemicals react with ozone, causing it to break apart and reduce the overall levels of ozone in that layer of the atmosphere.
How does CFC reach the stratosphere?
CFCs are released into the atmosphere from human activities like air conditioning and refrigeration. Once in the atmosphere, they are carried up into the stratosphere by wind and air circulation. In the stratosphere, CFCs can remain for many years, allowing them to break down ozone molecules through chemical reactions.
