Can you renew the ozone layer once it is lost?
The ozone will be formed but it will be next to impossible. The layer forming would be difficult.
The ozone is a finite resource. It once destroyed, that molecule is lost.
Chlorofluorocarbons (e.g. freons - as once used in spray cans, refrigerators, freezers, and air conditioners). They rise through the atmosphere to the ozone layer where UV decomposes them, releasing the chlorine gas which catalyzes the destruction of ozone in that layer. These chemicals have been phased out as much as possible, replaced by hydrochlorofluorocarbons (which decompose nearly completely in the lower atmosphere, never reaching to ozone layer) or fully fluorinated fluorocarbons (which contain no chlorine… Read More
no it comes from us and goes to the ozone Answer: Studies downwind of the Rockies in ALberta show that stratospheric ozone can be downwashed to the surface (troposphere), once at that level ozone is a pollutant.
Chlorofluorocarbon gases (CFCs) eat the ozone layer alive where we use it everyday for industrial processes although the ozone layer can repair Itself. Another answer: The number one reason ozone thins in our atmosphere is due to a lack of sunlight. Without this energy, ozone naturally will decay into oxygen molecules. This is why the hole in the ozone layer only appears over the poles and then only at the end of the winter months… Read More
recently it was discovered that the ozone layerwas getting depleted. various man-made compounds like CFC's (carbon compounds having both flourine and chlorine which are very stable and not degraded by any biological process) were found to persist in the atmosphere. once they reached the ozone layer, they would react with the ozone molecules. this resulted in the reduction of the ozone layer and recently they have discovered a hole in the ozone layer above the… Read More
Pollution is not a ozone layer issue. The "hole" in the ozone layer is a thinning of the layer (mostly above the South Pole) that occurs each year for a short period (about 4 months total cycle) because the sun is unable to hit the layer. Ozone is a very unstable element and with energy from the sun it degrades into simple oxygen (O2). The layer is normally about 3 mm thick and once a… Read More
Ozone is continually made and destroyed by the Sun. If we'll quit messing with it by making inert molecules with chlorine or bromine, and stop dumping large quantities of water vapor at high altitude, the ozone layer will recover. It will still have an ozone hole, once a year, when it is late winter / early spring at a pole. That's Nature.
The ozone layer is not small. The large concentration of ozone is destroyed by ozone hole. It will thus take time to heal.
Still Peru once a year, or any of the countries on the equator year round.
No, you won't. You can't carry an umbrella all time.
Excessive ozone in the ozone layer will decay rapidly to near current levels. It is unstable and breaks down with time. It would take a catastrophic event to make too much more than we currently do. If the ozone layer stayed where it was, and got twice as thick, then we'd have less UV-B striking Earth's surface, fewer cataracts, fewer melanomas, probably higher crop yields. We would also face extreme global warming as ozone is… Read More
because everything is based on a limted contact, once it expires, netflix aims to renew right away.
The ozone hole first appeared when the ozone layer first appeared. The only variable is the "size" of the hole, and the ozone concentration in the "hole". The pole of the Earth that is experiencing winter receives none of the UV that makes ozone (for like a month or more), and ozone naturally decays with time. TThe ozone hole is a normal feature of our ozone layer. It appears each year when it is winter… Read More
There is no connection between the two issues. The thinning of the ozone layer that we see over each pole during their winters is an event caused by CFCs and other halogen gases releasing chlorine and bromine, as well as a lack of sun hitting that layer. Once the daylight returns, the hole gradually fills up.
CFC is lighter than air just like hot air. Once freed, it rises readily to the upper atmosphere at the level of the ozone layer where it can react with the extra atom of oxygen in the ozone.
First of all, ozone is made up of three oxygen atoms. The function of this ozone is to keep out the most harmful of the Sun's rays. When struck by these rays the ozone spilts. The atoms fly around until they encounter other free atoms. Once three combine, new ozone is formed. Thus the ozone is self-sustaining.
The ozone hole is a natural occurrence. You cannot prevent it. You might keep it from starting sooner, have more ozone in it, or from lasting longer.... but you cannot stop it from forming once a year at each pole when it is late winter / early spring there.
Ultra violet radiation is bad, but once it goes through the ozone layer in the stratosphere is it harmless if a little hits you.
Why air pollution that was once blamed for global cooling is now considered responsible for global warming?
Air pollution that was once blamed for global cooling is responsible for warming because it has depleted some ozone some pockets of the ozone layer which were responsible for preventing harmful UV rays from penetrating it.
It turns into a meteorite once it enters the ozone layer, sometimes even breaking up in to hundreds ofpieceshence"meteor shower"
The sun maintains the levels of ozone in our atmosphere by creating O3 molecules out of O2 molecules that are in the air naturally. When the sun is unable to hit this layer, as it does each year at both poles, you get a thinning of this layer we refer to as the hole in the ozone layer. This hole lasts for about the same time as this solar nights at each pole and it's… Read More
The hole in the ozone layer only occurs over the poles during the end of the winter at each pole. The only large thinning area occurs in the Antarctic. This is because of the long winter nights preventing the sun from making more ozone. Once the polar night ends, the hole repairs itself. The Arctic hole is referred to as the dimple by NASA because of the small thinning that occurs over that pole.
It get's colder as you travel up into the atmosphere because the ozone layers block away a lot of heat. But once you get to the tropsphere layer te temperature is about 1,600 degrees because the sun goes throught that layer first, and that layer is about 500 kilometer's thick.
there is no black hole, but a thinning of the ozone levels over the Antarctic every winter. This has been happening for centuries due to a lack of sunlight hitting the oxygen in the area. Because ozone decays so quickly, sunlight must hit oxygen to create more ozone or the thinning occurs. The hole disappears once sunlight hits the area.
Ozone depletion once considered as something irrelevant is now a days one of the hot topics in the concern of all environmentalists in the modern world. earlier it was thought that the ozone depletion and global warming had no interconnection but studies have proved that these two are highly interconnected as global warming can cause ozone depletion and ozone depletion can cause global warming. Thus without the ozone layer i.e. if ozone depletion occurs at… Read More
Chlorofluorocarbons used to be the propellant of many aerosol sprays. They are no longer used because of the negative impact the chemicals had on the ozone layer.
Chloro Fluro Carbons (also called CFCs) are gases made up of three elements Chlorine, Fluorine and Carbon. They were once widely used as a coolant in refrigerators and as a propellant in aerosol cans. It was discovered in the late 1970s and early 1980s that CFCs from old and damaged refrigerators and old aerosol cans gradually found their way into the upper atmosphere where the they damaged the ozone layer. The ozone layer protects the… Read More
Yes. The holes in the ozone layer only occur at the poles and only at the end of their winters when the sun has been unable to react with oxygen to create this unstable gas. Once the sun returns to the area, the holes quickly disappear until next season.
The ozone layer is pool of ozone molecules. They are present in the atmosphere.
Short Answer: The *hope* is that there will eventually be a significant decrease in UV-B transmitted through to Earth's surface, off the equator where most people live. CFC can (so far) only be permanently be removed by energetic UV, which is found in-and-above the ozone layer. Once we stop adding these (and similar) compounds to the atmosphere, they will eventually degrade and stop whatever contribution they are making to ozone depletion. One symptom of improvement… Read More
To renew BBM (blackberry messenger) you must text the code depending on your once off bundle providers.
No. The ozone layer is self healing, once the megatons of Manmade chemicals are removed from the upper atmosphere. Lofting any sort of "band-aid" solution will cause more damage than the chemicals are currently doing... even water vapor depletes ozone and fuel combustion produces water vapor. The solutions require time: restore forests, reduce high altitude flights, stop using extremely stable chlorine- and bromine-containing compounds without recovery, reclaim ozone destroying compounds from the air.
Don't use items that involve adding harmful gases into the air because they can affectively burning holes into the Ozone layer. Such as: petrol powered lawnmowers, cars as much. To help with this: cut your grass only in the summer once or twice every other month. And to stop using cars as much ride a bike, walk or car share to the shops,work, school, etc.
Accpeting Yeshua as Master and Savior is only done once. Sometimes peope get lost in daily living and fall away, but they need to RECEIVE Him again, they only need to RENEW their relationship with Him.
Basically, A extreme amount of thrust must be first produced for the rocket to reach the excessive hight needed. Once it's reached the speed needed it can easily breach the Earths Ozone layer.
Increased cancers of all sorts. Mutation in all surface organisms. Decreased crop yields. But it is self-correcting. Once all Mankind is dead (or suddenly wises up), and the last of His contributions to depletion are removed / neutralized, Nature can repair the ozone in a matter of days.
It's called the ozone hole, though it's actually more like an extreme thinning of the layer of ozone. Ozone is a molecule with three atoms of oxygen instead two. The oxygen gas is a molecule of two atoms of oxygen. But ozone is not so. These ozone molecules are able to arrest the UV radiations those coming from preferably from the sun and re radiate in some other form of energy which are not harmful… Read More
once every five years
Once a year.
Not at all. Carbon dioxide is a gas that plants use to sustain life. The ozone layer thins each winter over the poles due to a lack of sunlight reaching that area during the long winter nights. Once the sun returns, the thinning area quickly disappears.
Chlorofluorocarbons (CFCs), once described as "miracle chemicals," because of the breakdown of the ozone layer that protects the earth from the sun's ultraviolet (UV) radiation which they caused.
The ozone level drops in winters. It is because depletion takes at cold weathers mainly.
Montreal Protocol was an international treaty signed by the united nation to reduce or stop the manufacture of Ozone depleting substances so that the depletion of ozone layer could be stopped or controlled. And moreover the Montreal Protocol has been successful in attaining its targets. In Countries like India the goals have been achieved around 2 years before the due dates. Montreal protocol has been a huge success in the field of ozone protection and… Read More
You renew annually (once a year)
The ozone hole presents no harm to humans. The ozone hole is a natural phenomenon that occurs once a year at each pole, and has since there has been an ozone layer and Earth has had an axial tilt. Contaminants cause the ozone hole to get larger / deeper, start sooner, and last longer. Contaminants deplete ozone everywhere, not just contributing to the ozone hole. Ozone depletion directly harms humans by: - increasing cases of… Read More
No, because you have to renew the Visa outside the US. The state recommends to renew in the homecountry, but Canada is also possible. Once it is expired there could be several problems to get back in the States.
Ozone once depleted cannot be used again. However new ozone can be formed naturally.
The ozone hole is a natural occurance, that occurs once a year at each pole. The southern polar hole is larger than the northern polar hole due to Earth's current magnetic alignment. The *size* of the hole is what is of concern... and something that the affairs of Man can play a part in. The hole is not really a hole at all, but a thinning of the Ozone layer due to a lack of… Read More
There is no limit to the number of ozone molecules the chlorine from a CFC molecule can destroy, or how long it will stay "up there". Over time, chlorine will find something else to bond to and leave the ozone layer. The hope is that once we stop delivering such compounds to the atmosphere, that can eventually happen. Right now estimations vary from 1 : 10,000 to 1 : 1,000,000 before it leaves the ozone… Read More
yes it does. you have to renew it every once and a while
