Explanation:
The ozone layer is a layer of ozone gas (O3) present in the Earth's stratosphere, which is about 10-50 km above the Earth's surface. It plays a critical role in protecting the Earth from the harmful ultraviolet (UV) radiation emitted by the sun.
Importance of Ozone Layer:
- It protects living organisms from harmful UV radiation.
- It is responsible for maintaining the Earth's temperature and climate.
Reason for Ozone Layer depletion:
The ozone layer is being depleted due to the release of human-made chemicals, such as chlorofluorocarbons (CFCs), which break down ozone molecules.
Effects of Ozone Layer depletion:
- Increased risk of skin cancer and eye damage in humans.
- Harmful effects on marine life and ecosystems.
- Changes in weather patterns and climate.
Measures to protect the Ozone Layer:
- Phasing out the use of ozone-depleting substances, such as CFCs, halons, and methyl chloroform.
- Promoting the use of alternative technologies and substances that are ozone-friendly.
- Educating people about the importance of the ozone layer and its protection.
Therefore, the ozone layer is present in the Earth's stratosphere, which is about 10-50 km above the Earth's surface.
