Answer 1

ozone hole is the area with ozone covering is depleted ..

Answer 2

Ozone is a form of oxygen that helps protect the Earth from some damaging ultraviolet radiation at high altitudes in the atmosphere. At lower altitudes it is a pollutant associated with smog. In the 1980s scientists first became aware of the existence of an ozone hole over Antarctica. Depletion of the ozone layer un the upper atmosphere allows more ultraviolet light to penetrate the atmosphere raising the risk of getting skin cancer and cataracts and other problems. It may also harm crop yields and sea life. Scientists who first raised warnings in the early 1970s about ozone damage won a Nobel Prize.

The ozone hole over Antarctica is usually more pronounced on the South American side of the frozen continent. Countries that are affected by it the most are Argentina, Chile, South Africa, New Zealand and Australia.

The largest ozone hole ever observed in the Antarctic was reported by NASA in September 2000. The hole spread out over 28.3 million square miles, more than three times larger than the United States. The ozone hole reached near-record size in 2003 and 2005, raising doubts about whether measures to combat ozone depletion were working.
