Study Notes
Ozone Hole
- The main cause of the ozone hole is the accumulation of ozone-depleting substances (ODS) in the stratosphere.
Ozone Depletion
- The phenomenon referred to as the ozone hole is the thinning of the ozone layer in the stratosphere, resulting in a decrease in total ozone.
Ozone Depletion Trends
- Since the late 1970s, there has been an observed decrease in total ozone in Earth's atmosphere.
Ozone-Depleting Substances (ODS)
- Ozone-depleting substances (ODS) are primarily transported into the stratosphere by atmospheric circulation patterns.
Ozone Depletion Mechanism
- The process of photodissociation releases atoms from the halogen group in the stratosphere, leading to ozone depletion.
