Study Notes
Ozone Depletion
- The primary cause of ozone depletion in the stratosphere is the release of chlorofluorocarbons (CFCs) and other halogenated gases, which contain chlorine and bromine atoms.
Ozone Formation
- Ozone (O3) is formed in the stratosphere when oxygen molecules (O2) are split by ultraviolet radiation, resulting in oxygen atoms that react with other oxygen molecules to form ozone.
Ozone Depletion Process
- When chlorine and bromine atoms come in contact with ozone, they catalytically destroy ozone molecules, breaking them down into oxygen molecules, leading to ozone depletion.
Function of Ozone Layer
- The ozone layer in the stratosphere acts as a shield, absorbing most of the sun's ultraviolet-B radiation, protecting life on Earth from its harmful effects.
Biodegradable Substances
- Biodegradable substances are materials that can be broken down naturally by microorganisms, such as bacteria, fungi, or yeast, into simpler substances like carbon dioxide, water, and biomass.
