When was the massive hole in the ozone layer over the Antarctica first discovered?
The ozone hole first appeared when the ozone layer first appeared. The only variable is the "size" of the hole, and the ozone concentration in the "hole". The pole of the Earth that is experiencing winter receives none of the UV that makes ozone (for like a month or more), and ozone naturally decays with time. TThe ozone hole is a normal feature of our ozone layer. It appears each year when it is winter at one of our poles. So it first appeared when the ozone layer appeared. We first noticed the ozone hole in 1985, above Antartica. One forms over the Arctic pole too when it is winter there. They heal closed again once sunlight reaches the pole. Its not so much the presence or absence of an ozone hole, but its size that is important. It is important to look out for the ozone hole
What else can I help you with?
Where is the hole in the ozone layer situated and when was it first discovered?
The ozone hole is mostly over Antarctica. It was first discovered in 1984.
What was the first country to get a hole in the ozone?
Antarctica was the first. It was because of the low temperature.
When was the year when you discovered the ozone layer disappearing?
In 1985, we discovered. It was done by Dr Farman.
The hole in the ozone layer of the earth was first discovered over what area?
Ozone layer formation was a natural process in which oxygen was converted to ozone by UV radiations. It is located about 20 to 30 kilometres (12 to 19 mi) above Earth, though the thickness varies seasonally and geographically.
In 1985 a hole in the ...was discovered over Antarctica.?
yes, and it was the "antarctic ozone hole"ozone layer

When was the massue hole in the ozone layer discovered?
The massive hole in ozone is discovered in 1985. It was discovered by Dr. Farman.

When was the first hole in the ozone layer found?
The first hole in the ozone layer was discovered in 1985 over Antarctica by British scientists using data from satellite observations. This led to the establishment of the Montreal Protocol in 1987, an international treaty aimed at phasing out the use of ozone-depleting substances.
When was the ozone layer first discovered?
1913
Who discovers that the ozone layer was already damage?
Dr Joseph Farman discovered Ozone depletion. He noticed it over Antarctica.
Where was an “ozone hole” discovered in the 1980s?
The ozone hole was discovered over Antarctica.
Above which region scientists discovered a hole in the ozonosphere in 1977?
Scientists discovered a hole in the ozone layer above Antarctica in 1977. This hole was primarily caused by the release of chlorofluorocarbons (CFCs) and other ozone-depleting substances into the atmosphere.
When was the hole in the o zone layer discovered?
The hole in the ozone layer was discovered in the 1980s by scientists monitoring atmospheric levels of ozone over Antarctica. It was first reported in a scientific paper in 1985 by British Antarctic Survey researchers. Subsequent research determined that the hole was caused by human-made chemicals, primarily chlorofluorocarbons (CFCs), released into the atmosphere.
