Why is the presence of ozone in the stratosphere beneficial for Earth?
Answer and explanation
Correct answer: Because it absorbs harmful ultraviolet rays
The governing concept is atmospheric protection. Stratospheric ozone absorbs a substantial part of the Sun’s harmful ultraviolet radiation, especially UV-B, before it reaches Earth’s surface. This reduces risks to living organisms, including skin and eye damage and harm to plants. Therefore option C is correct. Ozone does not increase nitrogen, convert dust into soil, or destroy every cloud; those claims are unrelated to its protective role.
