Answer 1

The ozone hole is the largest over Antarctica.

Explanation:

In the 1980s, scientists discovered a large hole in the ozone layer over Antarctica, which is as big as the USA. The depletion of ozone is most severe over Antarctica compared to other parts of the world. This is caused by chemicals like chlorofluorocarbons (CFCs) that break down the ozone molecules. Although ozone depletion also occurs near the North Pole and other regions, the hole over Antarctica is the largest and most well-known.
