What is Ozone?
Ozone is a mol-ecule
made of 3 atoms of oxy-gen
Ozone is a bluish gas
Ozone helps absorbs harm-ful UV radiation from the sun

What is the Ozone Layer?
Layer of ozone found in the stratosphere
Discovered in 1913 by French physicists Charles Fabry and Henri Buis-son
Ozone layer created by oxygen-ozone cycle

Importance of Ozone Layer
Protects organisms from harm-ful UV rays.
keeps the surface from heat-ing up

UV Rays 3 types of UV
rays UV A rays are
the least harmful
UV B rays can cause skin cancer/genetic problems
UV C rays completely are blocked

What is Ozone Layer Deple-tion?
Deterioration of ozone layer
CFCs are the main agents
Chlorine and Bromine
More UV rays reach the sur-face
![Page 7: Ozone is a molecule made of 3 atoms of oxygen Ozone is a bluish gas Ozone helps absorbs harmful UV radiation from the sun.](https://reader035.fdocuments.us/reader035/viewer/2022062421/56649da65503460f94a91618/html5/thumbnails/7.jpg)
Importance of Ozone Layer Depletion
Without the ozone layer surface heats up
Change climate More UV rays reach Earth Cause more genetic diseases Effect ecosystems

Causes of Ozone Layer Depletion
ODS are Ozone depleting sub-stances
CFC are the main chemical that breaks down Ozone Layer
HCFC and PCB and halons Volcanic Activity, Green House
Gasses, and Sun Spot cycles

Solutions
Decrease the use of products that contain CFC
Planting Trees Avoid Deforestation Check the leakage of vehicle air Decrease emissions of chlorine,
bromine, Raise awareness of ozone layer de-
pletion Help pass laws that regulate emis-
sions of harmful pollutants

the Ozone Layer Montreal Protocol Annual RAD reports Phase-out Management Plans
