What is the Ozone Layer? On a piece of scrap paper, write down what you think the ozone layer is.
Ozone Gas Consist of 3 oxygen atoms Absorbs UV radiation from sun found in the stratosphere, about 25 km (15 miles) above the earth's surface
Health of our Ozone Layer Is our ozone layer healthy or is it thinning?
CFCs Gases called chlorofluorocarbons (CFCs) damage ozone layer – Propellants in aerosol cans, refrigerator coolant – Most are banned today, however effects linger for a century
How CFCs Hurt In atmosphere they absorb UV radiation Then decompose into chemical products Products react with ozone Ozone becomes regular Oxygen, no UV protection
Air pollution and the ozone hole
