What part of the world can we find the biggest hole in the ozone layer?

Answer 1

Antarctica has the largest ozone hole

Answer 2

Antartica region has the biggest hole in the Ozone Layer

Answer 3

The so-called ozone hole in Earth's atmosphere, observed over Antarctica in September 2000, was as large as any ever seen.
The area of the hole in September 2000 was 11.4 million square miles.


The second largest hole formed in 2003 and covered 11.1 million square miles.
Those big ozone holes covered all of Antarctica and beyond to the southern tip of South America. By comparison, the area covered was three times the size of the United States without Alaska, or the continent of Australia.

Years of data. The first satellite measurement by satellite of ozone over Earth was recorded by NASA in 1979.

1998. A very large ozone hole in September 1998 covered some 10.5 million square miles. It was the record size before 2000.


2000. The mammoth Antarctic ozone hole in September 2000 reached across about 11.4 million square miles. It was the largest ever recorded. That area would be roughly three times the size of the United States. Later, the 2003 ozone hole covering 11.1 million square miles would be second largest.

2001. In September 2001, the Antarctic ozone hole covered about 10 million square miles. That was smaller than 2000, yet larger in area than the United States, Canada and Mexico combined.

2002. The ozone hole receded and in September 2002 was the smallest since 1988. Not only was the 2002 hole over Antarctica much smaller than in 2000 and 2001, but it had split into two separate holes. The small size may have been due to unusually warm conditions and the split may have been due to peculiar stratospheric weather patterns.

2003. The 2003 ozone hole covered 11.1 million square miles, making it the second largest ever recorded. The year 2000 was largest. Its growth was helped by calm winds and very cold weather.

2004. In September 2004, the ozone hole was 9.4 million square miles. That was smaller than 2003, possibly due to a relatively warm Antarctic winter.

2005. The winter hole in the ozone layer above Antarctica appears to have grown from last year but is still smaller than in 2003, when it was at its largest, according to the World Meteorological Organization. The 2005 hole will cover about 10 million square miles. WMO weather data showed that winter 2005 was warmer than 2003, but colder than 2004.

Answer 4

The hole in the ozone layer over Antarctica has grown to its greatest size yet, the US space agency says.

Nasa says this year's hole in the ozone layer - an annual event around September and October - measures 28.3 million square kilometres (11 million square miles).

That is three times the size of the United States. The previous record was 27.2 million square kilometres (10.5 million square miles), two years ago.

Answer 5

Anatarica every spring (September and October). In the 1970's a huge hole was devloping over the Arctic that extended till Southern Canada. This was caused by CFC's and the ozone appears to be recovering slowly.

Answer 6

Well... the ozone layer is thinning at the polar regions more rapidly than any other regions.The harmful CFC (Chlorofluorocarbon) emitted by several home appliances,i.e.refrigerators,AC machines etc. are causing thinning of ozone layers over big metropolises and industrial areas.

Answer 7

hii

i think the ozone layer is getting thinner at the poles especially at the soth pole due to which the glaciers are melting very quickly. which may result in wide spread flooding of the coastal areas around the world in the near future.

Answer 8

actually they r not holes...but the ozone layer is geting thinner which allows the UV rays of the sun to enter into the earth..
it is mainly taking place near the polar zones...as a effect of that ice caps r getting dissolved...the global warming is also a effect of this

Answer 9

Australia

Answer 10

Over the most industrialised nation where CFC is was widely used before the RIO DE GENERIO conference. I think its america but recently i read in newspaper that scientist have witnesed that the layer is slowly coming to normalcy after the world over ban on usage of CFC .
