What do chemicals released into the atmosphere break ozone down into to?
CFC's are released into atmosphere. They break the ozone into oxygen molecules.
Chloroflurocarbons may be harming the ozone layer by?
Chlorofluorocarbons (CFCs) were emitted during the 20th century from aerosols, refrigerators and other appliances. When CFCs reach the ozone layer (up to ten years later) the chlorine molecules separate and destroy ozone molecules. The chlorine survives and lives to fight again. CFCs can remain in the atmosphere for up to 75 years. CFCs are no longer being emitted to the atmosphere and scientists hope the ozone layer will have repaired itself by 2060.
What are 3 chemicals that can cause ozone molecules to break down in the ozone layer?
Water vapor, chlorofluorocarbons, and bromofluorocarbons.
What is the role of CFC in ozone destruction?
CFC's have the major role. They are the ones that deplete the ozone.
What is ozone layer depression?
The ozone depletion is the lowering of ozone molecules. It is the depletion of the molecules due to the depleting substances used. Freons are one such depleting substances.
What allows ozone to form easily?
Pollution containing Oxygen, and Solar radiation. The Solar radiation from the Sun causes the Oxygen molecules in pollutants to bond and the carbon molecules to break away, causing Ozone (O4) to form.

What are the groups of pollutant gases which break up the ozone molecules?
CFC's are the group of pollutant gases. They break up the ozone layer.
What is the material that causes the destruction of the ozone layer?
The destruction of ozone layer is caused by chlorofluorocarbons. These compounds initiate a chain reaction in the ozone layer which destroys these molecules.
What are 3 chemicals that can cause ozone molecules to break down in the ozone layer?
Water vapor, chlorofluorocarbons, and bromofluorocarbons.
What is the role of CFC in ozone destruction?
CFC's have the major role. They are the ones that deplete the ozone.
CFC's may cause ozone depletion by?
CFC's may cause ozone depletion by reacting with ozone. They react and decompose them to form other chlorine and fluorine compounds thus depleting the ozone layer.
Can ultraviolet radiations decompose oxygen molecules resulting from chlorofluorocarbon compounds erosion of the ozone layer?
Yes they do. It is the process that happens during ozone depletion.
What is the pollutant believed to be causing damage to the ozone layer?
The pollutant that is beleived to be causing damage is CFC. It is a synthetic chemical that might lead to ozone depletion.
What are ozone layers confined of?
Ozone layer is confined of ozone molecules. These molecules form a huge pool of ozone molecules.
Is freon a danger to the ozone layer in the stratosphere?
Freon is a brand name, and covers many compounds / molecules that have fluorine bonded into them. Fluorine itself is more powerful than ozone, so the fluorine provides no challenge to ozone in terms of accelerating its decay, or blocking its production. There are several of these molecules that also contain chlorine or bromine, and they *do* provide an accelerated decay path for ozone. These molecules are referred to as CFCs in general. Additionally, some of these molecules contain hydrogen, and this also provides a challenge to ozone. These molecules are referred to as HCFCs, and tend to break up before they make it all the way up to the ozone layer (a trip of many months). So... just being "freon" does not make it a danger to the ozone layer, nor does it prevent it from being a danger to the ozone layer. It depends on the formulation.
