Normally, an oxygen molecule contains 2 oxygen atoms. But in the upper atmosphere, there exists an oxygen molecule which contains 3 oxygen atoms. This molecule is called ozone. The ozone molecules form a layer around the earth called the ozone layer. This layer absorbs the sun's harmful ultraviolet radiation and thus, protects us.
But a time came, when the production of human-made chemicals like chlorofluorocarbons or CFCs increased a lot. These CFCs began to break more and more and more oxygen molecules, thus thinning or depleting the ozone layer. This depleting ozone layer is termed as ozone hole.
However, now a days due to awareness, the production of CFCs has reduced to a significant amount. As a result, the ozone layer is slowly but surely getting replenished.
