How does the ozone layer affect life on Earth? How do CFCs cause the ozone layer to break down? How do wildfires affect the ozone layer? How does burning fossil fuels affect the ozone layer? How do volcanic eruptions affect the ozone layer?
1) How do CFCs play a role in ozone depletion? Explain and include an equation to demonstrate your answer 2) What are the health effects of ozone in polluted air? Explain how pH is maintained in the human body. What could happen if your pH is too high or too low? Answer i...
Chlorofluorocarbon (CFC) is one of the chemical used by humans that cause ozone depletion. CFCs are man-made chemicals which are used as refrigerants, solvents, foam blowing agents, and outside the United States, as aerosol propellants. Since CFCs are volatile and water insoluble, they can ...
–along with CFCs – alsoabsorb infrared radiation, trapping heat inside the atmosphere rather than allowing it to escape back into space, creating a greenhouse effect that warms the planet. How do refrigerants harm the environment? Most refrigerants are known for having a negative effect on the...
Hydrofluorocarbons (HFCs): Solvents, refrigerants, firefighting agents and propellants for aerosols use HFCs as a replacement for ozone-depleting chlorofluorocarbons (CFCs). Perfluorocarbons (PFCs): There are relatively low amounts of PFCs in the atmosphere, but they're hard to get rid of. ...
Chlorofluorocarbons (CFCs) react with the ozone layer, causing a hole that exposes the surface of the earth to stronger UV radiation. Unfortunately, CFCs are also extremely useful for many purposes, and are used in refrigerants, aerosols and solvents.
However, as our ozone layer depletes due to use of chlorofluorocarbons (CFCs), UV levels are increasing. This can lead to health effects like skin cancer [source: EPA]. X-rays: X-rays are very high-energy light waves. We're most familiar with their use in a doctor's office, but X...
In the 1970s, it was discovered that the CFCs then in use are harmful to the ozone layer, so as of the 1990s, all new refrigerators and air conditioners use refrigerants that are less harmful to the ozone layer. A gas refrigerator usesammoniaas the coolant, and water, ammonia and hydroge...

There is still a hole in the ozone layer, but it's shrinking, according to NASA. There has been a 20% decrease in the hole thanks to a ban on chlorofluorocarbons (CFCs). "We see very clearly that chlorine from CFCs is going down in the ozone hole, and that less ozone depletion is...
