- The ozone layer
- Troposphere
- harmful effects on the respiratory system
- Stratosphere
- Protects living organisms by preventing harmful UV light from reaching the Earth's surface
- UV-a
- reaches Earth's surface. Doesn't cause much concern.
- UV-b
- Can cause sunburn and sometimes genetic damage which can result to skin cancer.
- UV-c
- Is entirely screened out by the ozone layer.
- Formation of ozone
- Firstly: O2 + (radiation 2O
- O2 + O --> O3 + heat
- How the ozone layer works
- O3 + (radiation < 310nm) --> O2 + O
- O2 + O --> O3 + heat
- Chemical energy released when O and O2 combine is converted to kinetic energy of molecular motion (heat)
- O2 + O ? O3
- Removal of Ozone
- O3 + O --> 2O2
- Troposphere
