Download Solution PDFThe correct answer is three.
Key Points
- Ozone is a molecule composed of three oxygen atoms.
- It is chemically represented as O3.
- Ozone is crucial in the stratosphere for absorbing the majority of the sun's harmful ultraviolet (UV) radiation.
- Ground-level ozone is a major component of smog and can be harmful to human health.
Additional Information
- Formation of Ozone
- Ozone in the stratosphere is formed when UV light strikes oxygen molecules (O2), splitting them into individual oxygen atoms (O).
- These oxygen atoms then combine with O2 molecules to form ozone (O3).
- Ozone Depletion
- Ozone depletion is primarily caused by human-made chemicals such as chlorofluorocarbons (CFCs).
- The Montreal Protocol was established to phase out the production of ozone-depleting substances.
- Ozone Layer
- The ozone layer is a deep layer in the stratosphere, encircling the Earth, that contains a high concentration of ozone.
- The ozone layer is essential for protecting life on Earth from the sun's harmful UV radiation.
- Health Impact of Ozone
- While stratospheric ozone protects life on Earth, ground-level ozone can cause respiratory problems and other health issues.
- Exposure to high levels of ground-level ozone can lead to conditions such as asthma, bronchitis, and other lung diseases.
