Ozone Layer

Ozone at the ground level is a pollutant. It makes harder to breathe.

It is ozone. It is present as the ozone layer.

The proper term used for a shallow zone near a shore is a littoral zone. This zone is the shallow waters between the land and the open water areas.

The CFC's molecules are ODS. They react with ozone to deplete it. The Chlorine and Fluorine are main atoms.

Montreal protocol was signed. It aims at protecting ozone layer.

If the CFC are not stopped, ozone will deplete. The hole will grow more bigger.

The amount of ozone has reduced. It is due to CFC.

Ozone day is celebrated to mark the saving of ozone layer. It is celebrated on 16 September.

because its melting the glaciers and rasing the ocean level also its making earth warmer Ground level ozone is a major component of smog and is responsible for respiratory tract and eye irritations. Exposure to high levels of ground level ozone may result in chest tightness, coughing and wheezing. People with respiratory and heart problems are at a higher risk. Ozone causes leaf damage to many plants and trees. People sometimes incorrectly assume that ground level ozone is the same as the atmospheric ozone that is thought by some to be a contributor to global warming.

Chloroflourocarbons were first created in 1928 and first marketted in the 1930's. They grew in popularity as non-toxic refrigerants, so about by 1988 consumption was a billion kg a year. Stratospheric ozone levels have been measured since 1956. In 1974 M.J.Molina and F.S.Rowland published a paper indicating that ozone and the chlorine from CFCs could interact to destroy the ozone if UV light was present. In May of 1985 Farman, Gardinar and Shanklin. published a report in Nature showing that ozone levels had dropped to 10% below normal January levels for Antarctica. Reworking old data indicated that there was evidence for the global ozone depletion as far back as 1976. In 1989 Anderson, J.G., W.H. Brune, M.H. Proffett, published in the Journal of Geophysical Research that ClO had been detected in the atmosphere, showing that CFCs were contributing to ozone depletion.

These here is not specified. What do what do to the ozone layer?

Ozone works in space that is our atmosphere. It protects us from harmful UV's.

Ozone production is very important. It is because the more ozone is produced the thicker will be the ozone layer.

Ozone *is* a greenhouse gas.

Some ozone is found in all layers of the atmosphere, but it does reach its peak cocentration in the lower stratosphere.

Note that the glass of a greenhouse is not down next to the plants...

EARLY ATMOSPHERE have humidity

The CFC's are used in almost all refrigerants. They provide cooling effect.

Propellants in aerosol cans, such as hydrocarbons like propane and butane, are not inherently carcinogenic. However, prolonged exposure to high concentrations of these propellants may cause health issues. It is important to use aerosol cans in a well-ventilated area and as directed.

Ozone is an isotope of oxygen. It acts as a filter to the earth.

Various natural activities also cause ozone depletion. Volcanic eruptions being the highest of them.

There are no objects in ozone. It contains just the ozone gas.

CFC's are responsible for depletion of ozone. They react with ozone to deplete it.

Ozone is very important to people. It protects them from harmful UV rays of the sun.
