What does the ozone layer help protect the Earth from?

• A. Carbon monoxide
• B. Harmful ultraviolet radiation
• C. Greenhouse gases
• D. Particulate matter

Answer: (B)

The ozone layer plays a crucial role in protecting life on Earth by absorbing the majority of the sun's harmful ultraviolet (UV) radiation. This layer is located in the stratosphere, approximately 10 to 30 miles above the Earth's surface, and consists of high concentrations of ozone (O3) molecules. UV radiation can lead to various health problems, including skin cancer, cataracts, and other serious effects on biological organisms. While other atmospheric pollutants like carbon monoxide, greenhouse gases, and particulate matter impact air quality and climate, they are not directly related to the protective function of the ozone layer. Thus, the ozone layer's primary and most significant function is its ability to filter out harmful UV radiation, making the answer regarding its protection from this type of radiation the most accurate choice.
