Why do holes in the ozone layer appear mainly in the polar regions?
The hole in the ozone layer over planet earth is caused by the interaction of man-made gasses -- CFCs or chloroflurocarbonswith sunlight which destroys ozone.Late winter/ early spring -- August in Antarctica -- is the coldest period over the continent, because of the lack of sunrises since fall. The sunlight situation in spring over the continent is called the circumpolar vortex and the result is the lack of ozone in the lower atmospheres, because the stratospheric air cannot penetrate the cold. (Stratospheric air contains more ozone.)Once sunrises occur and sunsets don't occur, the lower atmospheres begin to recover making September and October the prime periods during which there is a 'hole in the ozone layer' above the continent.The source of this material is WeatherQuestions dot com.
What is good ozone?
Ozone is an unstable form (activated, allotrope) of oxygen that is contained the air, in fact is a gas that is generated in natural form in the atmosphere, product of diverse climatic and environmental conditions, and has a scent similar to the one of the "wet earth".The highest levels of ozone in the atmosphere are in the stratosphere, in a region also known as the ozone layer between about 10 km and 50km above the surface (or between about 6 and 31 miles). This layer surrounds earth and protects it from the dangerous solar rays. Ozone its mostly produced from ultraviolet rays reacting with oxygen, and is the only substance in the atmosphere that can absorb the dangerous ultraviolet (UV) radiation that would be harmful to most form of life in earth.Industrially it is generated applying an electrical tension sufficient to excite oxygen turning it ozone , by means of ozone generators (known also like: ionizes, purifying ozone, etc.)See "What is ozone?" in the "Related Questions" section below.
