Ozone is a layer that is present in troposphere and protects us from the excessive heat of the sun.

What is the Ozone Layer?
The ozone layer is a region of Earth's stratosphere that contains a high concentration of ozone (O₃) molecules. This layer plays a crucial role in protecting life on our planet.
Importance of the Ozone Layer
- Protection from UV Radiation: The ozone layer absorbs the majority of the Sun's harmful ultraviolet (UV) radiation. This is essential for protecting living organisms, as excessive UV exposure can lead to skin cancer, cataracts, and other health issues.
- Climate Regulation: By filtering UV rays, the ozone layer contributes to climate stability, influencing weather patterns and temperature regulation.
Composition and Location
- Location: The ozone layer is situated approximately 10 to 30 miles above Earth’s surface, within the stratosphere.
- Composition: It consists primarily of ozone molecules, which are formed when UV radiation splits oxygen (O₂) molecules, allowing individual oxygen atoms to combine with other O₂ molecules.
Threats to the Ozone Layer
- Chlorofluorocarbons (CFCs): These chemicals, once commonly used in refrigeration and aerosol sprays, have been responsible for ozone depletion.
- Global Efforts: The Montreal Protocol, established in 1987, aimed to phase out the use of CFCs and other ozone-depleting substances, leading to significant recovery of the ozone layer.
Conclusion
The ozone layer is vital for life on Earth, serving as a shield against harmful UV radiation. Continued global efforts are essential to preserve this protective layer for future generations.
