Since decades, Antarctica has been a place of intense scientific research. Various countries have established their bases in Antarctica to study the impact of climate change. The ozone hole was discovered in 1985 in Antarctica. Which of the following is true regarding ozone hole?
Ozone hole region in Antarctica is due to thinning of the stratospheric ozone layer. Ozone hole is caused by increasing concentrations of ozone-depleting chemicals in the stratosphere that come from spray cans, refrigerants, and air conditioners.Once they reach the ozone layer, they will react with the ozone molecules.This will result in a reduction of the ozone layer. In the absence of ozone layer, there will be a direct exposure to ultraviolet rays of the Sun which can cause a variety of health-related issues such as cancer, mutations, etc.
