What is natural ozone's part
Uv radiation, most absorbed by ozone layer
1 of 12
How does human interferance effect ozones part
Less ozone due to pollutants, more Uv gets to earth surface
2 of 12
What us UV A
Safest, allows vitamin D to form, longest wavelength
3 of 12
What us UV B
Dangerous, Splits ozone
4 of 12
What is UV C
Most Dangerous, Shortest wavelength, Splits ozone and o2
5 of 12
How do humans change ozone by CFC production
CFC reach stratosphere, UV light splits Chlorine from CFC, Chlorine reacts with O3, takes 1 oxygen atom, creates ClO, leaves behind o2, Can drop oxygen an gain more, process repeats, this allows more uv B and C to pass through to earth
6 of 12
Consequences of Ozone depletion on human life
Skin cancer- mutation within cells, Blindness- cataracts in eye
7 of 12
Consequences of Ozone depletion on plant life
Damage plant tissue, knock on effect for gasses in atmosphere and food for other species
8 of 12
other Consequences of Ozone depletion on human life
Fading of materials like car tyres, window frames
9 of 12
What is a Method to reduce CFC production + details/dates
1987, Montreal protocol, Banned use of CFC's in developed countries, NIC's didnt sign up
10 of 12
Replacement material than can be used instead of CFC for fridges
Use of HCFC's in fridges, (Hydro-Chlorofluorocarbons), shorter life, dont reach as far up and shorter lifespan
11 of 12
Replacement materials that can be used to Reduce CFC production
convection currents for cooling buildings, trigger spray/roll on/ butane, cardboard packaging
