Does the ozone layer trap carbon dioxide in the atmosphere?
It doesn't. The ozone layer has *nothing at all* to do with trapping CO2.
Above the level of the ozone layer, intense radiation breaks CO2 down, so you get fooled into thinking the ozone layer had something to do with "trapping".
How can you save the ozone layer for kids?
# Minimize high altitude aircraft flights (oxygen reduction and water vapor deposition) # Minimize rocket flights (water vapor deposition) # Encourage growth of plants that produce oxygen, discourage deforestation # Decrease / control releases of high temperature steam / moisture to the atmosphere # Eliminate production and release of known ozone depleting chemicals (such as CFCs and HCFCs) where remotely possible. Subsidize production of safer alternatives where possible. # Establish controls to assure that new compounds to be used in high volume, are surveyed for effect on ozone. CFCs and other compounds have been identified as compounds that catalytically break down ozone. Many countries have stopped using most of them (aerosol cans, industrial pollution etc..), and so they will eventually move out of the "ozone layer," where they can do little harm.
The ozone hole is an area where ozone concentrations are lower than normal. It occurs because of various factors: # If there is little UV light to make new ozone -- when winter comes to the poles where the ozone holes form, the ozone decays with time if for no other reason. We can't do much about this. # If there is little oxygen to make ozone. # If there are compounds (many inadvertantly produced by humans) that consume and deplete oxygen and/or ozone. # If there are compounds that catalytically convert ozone back to oxygen. We can't 'fix' the hole per se, but we can do things to PREVENT it from getting bigger. Note that there is a 10-20 year "delay" between CFC emissions and ozone depletion -- we are experiencing the effects of CFC emissions from the '70s and early '80s. The laws/regulations that have been passed are to compensate and prepare for future increases in ozone depletion due to our past, present, and future actions concerning pollution and CFC emissions. Actions an indivdual can take (see the link below for more): * Try to use products which are labeled "Ozone-Friendly" * Ensure technicians repairing your refrigerator or air conditioner recover and recycle the old CFCs so they are not released into the atmosphere. * Vehicle air conditioning units should regularly be checked for leaks. * Ask about converting your car to a substitute refrigerant if the a/c system needs major repair * Help start a refrigerant recovery and recycling program in your area if none already exists. * Replace halon fire extinguishers with alternatives (e.g. carbon dioxide or foam). * Suggest school activities to increase awareness of the problem and to initiate local action.
#1:stop using aerosol cans
#2:dont drive cars
#3:stop water vapor
#4:something to do with CFC's{chlorofluorocarbons}
#5:something about tetrachlorie and methyl-chloroform
That's all I know
we can start using electric cars or hybrids and stop using hair spray
1. Don't use cars that use gas and try to buy cars that use electricity.
2. If your a/c in your car is leaking take it to a repair shop quickly or CFC will go in the air and that is bad because CFC hurts our ozone layer.
3. Plus you shouldn't use aerosol cans.
4. You should tell your school about earth's ozone layer so people will help us save the ozone layer.
5. Buy refrigerators with lower watts.
6. Stop using CFC's. CFC means "Chlorofluorocarbon". CFC's are a type of chemical that is used in spray cans to make them spray and in refrigerators to make stuff cold.
What are the advantages of ozone layer?
Brand new organisms will get to starve for lack of food, as all the species mutate. Plenty of cancer to go around. If the organisms have eye structures similar to humans, they will get more cataracts that will let them be preyed on more easily
Nominally reduced moderation of Earth's surface temperature.
New Species will develop or evolve and the earths atmosphere will be distorted. We will be forced to live maybe on Mars. Or we could evolve rapidly as well.
What layers contains the ozone layer?
Ozone is naturally formed and found in the atmosphere. It can also be found at ground level, but this is considered to be the "bad" ozone because it comes from pollutants. The atmospheric layer that has the highest concentration of ozone is the stratosphere. The ozone layer is mainly located in the lower portion of the stratosphere from approximately 10 km to 50 km above Earth's surface, though the thickness varies seasonally and geographically.
How does the ozone benefit living things on earth?
Ozone present in the stratosphere is helpful as it blocks the harmful ultraviolet radiations from the sun. This ozone present in the atmosphere as ozone layer acts as a shield for earth against these harmful radiations.
Is methane destroying the ozone layer?
Methane has no effect on the ozone layer. Ozone cannot get to the carbon atom, so they coexist happily.
However, oxygen in the stratosphere does experience a chemical reaction with methane. Emissions of methane are transformed into water, according to the formula CH4 + 2O2 --> CO2 + 2(H2O). Ozone is O3, so it is unaffected.
What chemicals are causing the ozone layer thinning?
CFC's cause hole in ozone. They react with ozone and deplete it.
Does smoking affect the ozone layer?
Smoking cigarettes does not directly affect the ozone layer. Ozone layer depletion is mainly caused by chemicals like chlorofluorocarbons (CFCs) used in refrigerants and aerosols, as well as pollutants from industrial activities. However, smoking can contribute to air pollution, which in turn can have broader effects on the environment.
How much percent part of sun's ultraviolet rays is absorbed by ozone layer?
98% is filtered, 2% gets through. See the link below.
All UV-C is gone, most of the UV-B is gone, leaving the UV-A pretty much alone.
Why is ozone harmful in troposphere?
There is normally no life that breathes in the stratosphere. In the troposphere, both plants and animals suffer when significant amounts of ozone are present.
How do cfc's breakdown the ozone?
CFCs break down ozone in the atmosphere when they are exposed to ultraviolet radiation. This causes the CFC molecules to release chlorine atoms, which then react with ozone molecules, leading to the destruction of the ozone layer.
Where is the thinnest layer of ozone?
The thinnest layer of ozone is at the poles. It is because the depletion is abundant at the poles.
What cause damage to the ozone layer?
Ozone depletion is the process where ozone holes are created in the ozone layer. It is caused due to the action of chloro-floro-carbons on the ozone molecule to break it down to oxygen.The substances that are causing ozone layer depletion are freons, CFC's etc..
These are called as ozone-depleting substances (ODS).
What does earths ozone layer filter?
The Earth's ozone layer filters out harmful ultraviolet (UV) radiation from the sun, particularly UVB and UVC rays. This helps protect living organisms on Earth from the damaging effects of excessive UV radiation, such as skin cancer, cataracts, and harm to marine ecosystems.
How is ultraviolet radiation from the sun affected by the ozone layer?
Ozone is made in all parts of the atmosphere. It is at its highest concentration in the lower part of the stratosphere. Below the "ozone layer", UV-B intensity is greatly diminished, which will decrease the available energy for certain ionizations of gases. The ozone layer is able to couple radiatively in the infrared, so it can tap heat energy of oxygen and nitrogen. The atmosphere doesn't really care what sort of gases it contains. So it is really hard to arrive at some sort of "effect" that would be interesting / significant...
How can the destruction of the ozone layer affect living organisms (including humans)?
The effect of ozone destruction is skin cancer. It also causes eye cataract.
How does stratospheric ozone absorb ultraviolet radiation?
Nitrogen breaks down into atoms when it absorbs UV-C or more energetic radiation.
Oxygen breaks down into atoms when it absorbs UV-C or more energetic radiation.
Ozone breaks down into atoms when it absorbs UV-B or more energetic radiation.
Was ozone present in the early atmosphere?
2.3 billion years ago marks the Great Oxidation Event (before life is expected to have climbed onto land). At this time, there would have been an ozone layer. yes, the ozone is needed for life
In which level of the atmosphere is ozone concentrated?
Ozone is concentrated in the stratosphere, which is the second major layer of Earth's atmosphere. This concentration of ozone in the stratosphere forms the ozone layer, which plays a key role in absorbing the sun's harmful ultraviolet radiation.
How are ozone and greenhouse gas alike?
They are both composed of oxygen atoms. Oxygen is O2, whereas ozone is O3.
The only layer below the stratosphere is the troposphere. The layer below this is the lithosphere, and it is already opaque to all light. Dirt is like that. Ozone concentrations equivalent to those found in the stratosphere, even adjusted for pressure: # Would be long-term fatal to all life on Earth, # Would require additional sources of power to make ozone, which would come from burning fossil fuels (even if all life did not die), # And would rapidly decay since ozone is quickly destroyed by the moisture in the air we breathe, and the temperatures we breathe it at. So lots of ozone production "stations" would be required. Ozone in the "ozone layer" is made when oxygen molecules are broken apart by UV-C, and UV-C is completely absorbed by the time the Sun's light reaches the bottom of the ozone layer. So UV-C cannot make an ozone layer deeper in the atmosphere. Ozone in concentrations of 10 ppm are the norm in the ozone layer. Concentrations of 0.08ppm cause breathing problems, and higher than 1ppm causes damage to vegetation even in short duration doses. Additionally, the temperatures and humidity of the lower atmosphere would rapidly decay the ozone, so we'd have protection shortly before noon, until late afternoon... by morning... we'd be unprotected from UV-B.
Harmful UV rays were always there. But we were protected from them by ozone layer.
Ozone layer does. It has a special property of absorbing CFC's.
