Question

Quizplus · Accepted Answer

Ozone holes are regions where the ozone concentration is significantly lower than normal, and they predominantly appear near the Earth's poles, particularly over Antarctica and to a lesser extent over the Arctic. This phenomenon is largely due to the release of chlorofluorocarbons (CFCs) and other ozone-depleting substances into the atmosphere.
