Yes - There is always just one ozone hole in the Earth's atmosphere. - The ozone hole forms over Antarctica because its winter allows the atmosphere to get cold enough for nacreous clouds to form in the ozone layer.
No - Ozone holes have more ozone than usual. - Ozone holes are areas where the ozone levels are depleted.
