What type of radiation does the ozone layer filter?

• A. Infrared Radiation
• B. Gamma Radiation
• C. Ultraviolet Radiation
• D. Visible Light

Answer: (C)

The ozone layer primarily filters ultraviolet (UV) radiation from the sun. This is crucial for protecting life on Earth, as excessive UV radiation can lead to various health issues, including skin cancer, cataracts, and weakened immune systems, as well as detrimental effects on ecosystems and wildlife.

While other types of radiation, such as infrared and visible light, are part of the solar spectrum, they do not pose the same level of harm to living organisms when compared to UV radiation. Infrared radiation is responsible for heat, and visible light enables sight, both of which are essential and not filtered by the ozone layer. Gamma radiation, on the other hand, originates from radioactive materials and is not significantly affected by the ozone layer. Therefore, the ozone layer's primary role is to absorb and limit the intensity of ultraviolet radiation, making it an essential component for maintaining ecological balance and protecting health.
