What appliances increase CFCs in the atmosphere?
Refrigerators and air conditioners are common appliances that can contribute to an increase in CFCs in the atmosphere. CFCs are used as refrigerants in these appliances and can be emitted into the atmosphere if not properly contained or disposed of.
How do human activities affect the global warming and ozone depletion?
Humans burning fossil fuels are causing global warming. This is continuing unchecked and is causing climate change. Human production of CFCs (now stopped) was responsible for ozone depletion. The ozone layer is very slowly recovering.
What activities of man contribute to the depletion of ozone layer?
In the 1970s humans released CFCs into the atmosphere. It was used as a gas in aerosol cans, refrigerators and air conditioners. Production of CFCs was phased out after the Montreal Protocol in 1989. Scientists hope the ozone layer will be repaired around 2050.
Does chlorofluorocarbons react with carbon dioxide?
Chlorofluorocarbons (CFCs) do not directly react with carbon dioxide (CO2) under normal conditions. However, CFCs are known to contribute to ozone depletion in the atmosphere, which can indirectly affect the amount of CO2 trapped in the atmosphere and contribute to climate change.
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.
Why is there a hole in the ozone layer?
The hole in the ozone layer is primarily caused by human activities releasing chemicals called chlorofluorocarbons (CFCs) into the atmosphere. These CFCs break down ozone molecules, leading to the thinning of the ozone layer.
What appliances increase CFCs in the atmosphere?
Refrigerators and air conditioners are common appliances that can contribute to an increase in CFCs in the atmosphere. CFCs are used as refrigerants in these appliances and can be emitted into the atmosphere if not properly contained or disposed of.
What are human made pollutants to the atmosphere?
Human-made pollutants include carbon dioxide from burning fossil fuels, methane from agricultural activities and landfills, nitrogen oxides from vehicles and industrial processes, and chlorofluorocarbons (CFCs) from air conditioners and refrigerants. These pollutants contribute to air pollution, climate change, and ozone depletion.

What do you called it destroys the atmosphere that surrounds the earth?
The destruction of the atmosphere that surrounds Earth is often referred to as atmospheric degradation or pollution. This can be caused by human activities such as burning fossil fuels, deforestation, and emissions of greenhouse gases that contribute to global warming and ozone depletion.
What percent of the chlorine in the atmosphere can be attributed to nature?
Approximately 90% of the chlorine in the atmosphere is attributed to natural sources, such as volcanoes and sea spray. The remaining 10% is mostly due to human activities, primarily from the use of chlorofluorocarbons (CFCs) and other industrial processes.
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.
What substance are thought to be main sources of chlorine radicals in the atmosphere?
The main sources of chlorine radicals in the atmosphere are man-made chlorofluorocarbons (CFCs) and other halocarbons. These compounds are released into the atmosphere from activities such as refrigeration, air conditioning, and aerosol propellant use. Once in the atmosphere, sunlight breaks down these compounds, releasing chlorine radicals that can contribute to ozone depletion.
What causes low ozone concentrations in the atmosphere?
Low ozone concentrations in the atmosphere are primarily caused by human activities such as the release of ozone-depleting substances like chlorofluorocarbons (CFCs) and other pollutants. These substances break down ozone molecules in the stratosphere, leading to a decrease in ozone levels.
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.
