The Ozone layer is the the atmospheric region called the stratosphere, and shields us from harmful ultraviolet B radiation that comes from the sun.
Which are best answers?
No - Ozone holes can be hole-shaped. - Actually the ozone holes are not actually holes, but an area where the ozone has been depleted or thinned.
Yes - Ozone holes allow ultraviolet light to reach the Earth's surface. - When ozone levels decrease, it allows UVB radiation to pass through and our surface is exposed.
No- Ozone holes don't have any ozone in them. - Ozone holes have lower levels of ozone in that area of the stratosphere.
Yes - Chlorofluorocarbons make an ozone hole larger. This is called the greenhouse effect. When we warm the earth's surface with these types of gases, they can trap energy from the sun. This makes it warmer on earth's surface. There has been a scientific link between CFC gasses and ozone depletion.
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.
