The o-zone layer importance of water
Like a spongethe ozone layer absorbs bits of radiation hitting Earth from the sun. With less ozone there is less heat released, amplifying the cooling in the lower stratosphere, and enhancing the formation of ozone-depleting polar stratospheric clouds, especially near the South Pole. Retrieved October 3, The stratosphere increases in warmth with elevation because ozone gas es in the upper layers absorb intense ultraviolet radiation from the sun. The thickness of the ozone layer varies worldwide and is generally thinner near the equator and thicker near the poles. The ozone layer lies approximately kilometers miles above the Earth's surface, in the stratosphere. They contain micro-organisms, animals and plants that provide us with half of the oxygen we breathe and much of the food we eat.
The ozone layer or ozone shield is a region of Earth's stratosphere that absorbs most of the If all of the ozone were compressed to the pressure of the air at sea level, it would be only 3 millimetres (1⁄8 inch) thick.

Although the concentration of the ozone in the ozone layer is very small, it is vitally important to life because it. Most ozone resides in the stratosphere (a layer of the atmosphere As long as water is poured into the bucket at the same rate that water is.
In particular, the ozone layer protects us from the UV radiation, known as UV-B, The most important are chlorofluorocarbons (CFCs), which at one time were Car dash boards, insulation foams in our houses and office buildings, water.
CFCs and halons cause chemical reactions that break down ozone molecules, reducing ozone's ultraviolet radiation-absorbing capacity. Although the Montreal Protocol was designed to phase out the production and consumption of ODSs, some replacements of these substances, known as hydrofluorocarbons HFCshave proven to be powerful greenhouse gases.
Depletion of this layer by ozone depleting substances ODS will lead to higher UVB levels, which in turn will cause increased skin cancers and cataracts and potential damage to some marine organisms, plants, and plastics. Dobsonwho developed a simple spectrophotometer the Dobsonmeter that could be used to measure stratospheric ozone from the ground.
WMO expresses concern about radio frequency decision. The majority of ozone is produced over the tropics and is transported towards the poles by stratospheric wind patterns.

NASA Ozone What is it, and why do we care about it
The thin layer of ozone that surrounds Earth acts as a shield, protecting the As long as the tap adds water as fast as the drain removes water, the water level in the tub remains constant.
The most important CFC's for ozone depletion are. The ozone layer, primarily known today for its role in shielding us from ago by the splitting of water molecules by the sun and more significantly, through the.
The Ozone Hole and Global Warming Union of Concerned Scientists
Nations that signed the Convention — called the parties — agreed to research and monitor the effects of human activities on the ozone layer and to take concrete action against activities that are likely to have adverse effects on the ozone layer. Warm air remains in the upper stratosphere, and cool air remains lower, so there is much less vertical mixing in this region than in the troposphere.
Countries who ratify the Kigali Amendment commit to cut the production and consumption of HFCs by more than 80 percent over the next 30 years.

The o-zone layer importance of water
|Greenhouse gases absorb heat at relatively low altitudes and warm the surface--but they have the opposite effect in higher altitudes because they prevent heat from rising.
Once released, these ozone-destroying molecules do their dirty work, breaking apart the molecular bonds in UV radiation-absorbing ozone. Large-scale increases in UV-B can alter the way carbon dioxide is exchanged between the atmosphere and the biosphere.

The residual effects of CFCs accumulating within the atmosphere lead to a concentration gradient between the atmosphere and the ocean. Healing the ozone layer is a major accomplishment, but it also proves something important as we look to the future, how to deal with other global environmental challenges. A working group between scientist among organizations with significant scientific capacity along with those from organizations with a need for significant increase in scientific capacity should be established to allow continued and enhanced scientific capacity among all parties of the Montreal Protocol.
Beginning January 1,only recycled and stockpiled CFCs were available for use in developed countries like the US.
