Consider the following statements.1. The rate at which ozone is being ...
The equilibrium between the formation and destruction of ozone, has been upset by the influx of several substances into the atmosphere which reacts with ozone and destroys it.
  • The rate at which ozone is being destroyed is much faster than the rate at which it is being formed.
  • It implies that there is a significant decrease in the concentration of ozone in a particular region of the atmosphere, hence the name ‘Ozone Depletion’.
  • The best example of such an Ozone Depletion is the atmosphere over the Antarctic which has only about 50 per cent of the ozone that originally occurred there. The actual realization of ozone-depletion came only in 1985.

Consider the following statements.1. The rate at which ozone is being ...
Explanation:

1. Rate of Ozone Destruction:
- The statement is correct as the rate at which ozone is being destroyed is indeed much faster than the rate at which it is being formed.
- Ozone depletion is primarily caused by human-made chemicals like chlorofluorocarbons (CFCs) and halons, which break down ozone molecules in the stratosphere.

2. Ozone Depletion over Antarctic:
- The statement is also correct as the best example of ozone depletion is the ozone hole that forms over the Antarctic region.
- The Antarctic ozone hole is a severe depletion of the ozone layer above Antarctica that occurs during the Southern Hemisphere spring (September-November).
- The ozone hole is characterized by extremely low ozone concentrations, with levels dropping to about 50% of their pre-1980 levels.

Conclusion:
- Both statements are correct as they highlight the significant issue of ozone depletion, especially over the Antarctic region where ozone levels have been drastically reduced. This depletion has serious implications for human health and the environment.
