What happens when a meteor hits the ozone layer?
When a meteor hits the ozone layer, it can cause localized heating and disruption of the ozone molecules. This can lead to a temporary thinning of the ozone layer in that specific area, which may allow more harmful UV radiation to reach the Earth's surface. Over time, the ozone layer can repair itself and return to its normal state.
Why is ozone layer disappearance a problem?
The ozone layer is not disappearing. The ozone layer may or may not be thinning.A thinning ozone layer results in increased rates of cancer and mutation, and reduced crop yields and loss of arable land.
True or false The main cause of the thinning of the ozone layer is global warming?
False. Man MAY be a contributor to the thinning, but the layer has thinned for centuries due to a lack of sun during the long polar nights in the winter. The largest thinning occurred in 1858, before man ever started using fossil fuels or CFC's
Chloroflourocarbons may be harming the ozone layer by?
CFC's may be harming the ozone layer. They do it by depleting the ozone, decomposing into single atoms.
How big was the hole in the ozone layer in 1880?
It is thought that the hole in the ozone layer was not present in 1880 as it is a result of human activities releasing chemicals like CFCs into the atmosphere over the 20th century. The hole started to be detected in the late 1970s and has been monitored since then.
Are holes in the ozone layer caused be burning fuels?
Not at all. The major source for the thinning area that we call a hole, which occurs over Antarctica during it's winter months is primarily due to a lack of energy (sunlight) on that area. No reputable science group and no scientist disagrees with this. We know the "hole" has been occurring for centuries. What some people believe is that the use of solvents and certain chemicals may have a negative affect on this layer and helping thin this area more in recent years. There are two holes which each occur annually. One over the Antarctic during their winter and the same in the Arctic during it's winter. These have happened since well before man made any chemicals. The items blamed for the hole by some is heavier then air and is only found in the ozone layer in extremely low volumes. There is no thinning over most of our planet, including areas where humans actually live and use CFC's. Burning of fossil fuels is blammed (by some) for the 0.2 degrees of warming we have seen the past 200 years. We have seen 11 degrees of warming though over the past 6000 years.
How can you help ozone layer depletion?
Ozone depletion is predominantly a natural event. the largest thinning occurred in 1858 due to solar activity and before CFC's were in use. Man may be contributing to the issue by using cfc's. These have been banned for many years now. The situation, if man induced, should take care of itself.
Are CFC's creating a hole in the ozone layer?
CFCs were produced to be refrigerants and propellants. They served a need of modern society. They were relatively cheap and easy to form. No one knew they damaged the ozone layer (to whatever extent they do). They know to check now. 3rd world countries still produce them, because they are still relatively cheap and easy to form.
What are the dangers related to the destruction of the ozone layer?
The thinning of the ozone layer annually is a very natural event and has been occurring for generations. Well before man invented CFC's or even walked upright. The impact that man may be having on this event is not fully understood. What is know though is that without this layer of protection, no life would exist in the planet.
What is the effect of CFCs on the ozone layer?
The CFCs are broken down, releasing chlorine in the process. The chlorine then breaks down the ozone in the stratosphere to form oxygen. When the ozone is broken down at a quicker rate than it can reform, holes in the ozone layer may appear. This allows more UV radiation to reach the surface of the earth and it is an issue in the southern hemisphere.CFC's react with ozone layer. This reaction causes their decomposition.
What can lead to the depletion of the ozone layer of earth?
Ozone layer depletion is the depletion of ozone. It has very bad affect on environment,
Why is ozone considered a pollutant in the ozone layer?
Ozone in the ozone layer is not at all a pollutant but it is something without which no ozone layer may have existed. Ozone can be considered as a pollutant in the stratospheric region but in the stratosphere or the ozone layer it is of full or complete use. No harms there.
