17. How is ozone different from oxygen?
Ozone is toxic, corrosive and not breathable.
Ozone is easier to breathe than normal oxygen.
Ozone only exists in the upper atmosphere.
Ozone is the same as oxygen .
18. How is stratospheric ozone created?
Ozone created from NOx and VOC gases rise from low altitudes into the stratosphere and form the ozone layer.
Radiant energy from the sun breaks apart oxygen molecules freeing single oxygen atoms that recombine into ozone.
Ozone is formed in when sulfur and nitrogen oxides combine with water in the atmosphere.
When ultraviolet radiation passes through a depleted ozone layer it acts on oxygen at ground levels creating ozone.
