If a layer has abundant ozone, how does it protect life on Earth?
Answer and explanation
Correct answer: By blocking harmful ultraviolet radiation
The governing concept is atmospheric absorption of radiation. Ozone, especially in the stratosphere, absorbs a large part of the Sun’s harmful ultraviolet radiation before it reaches Earth’s surface. This lowers damage to skin, eyes, plants, and other organisms, so option A is correct. Earthquakes, volcanic gases, and sea salts are unrelated to ozone’s protective function.
