Ozone and carbon dioxide are both small in amount yet why are both important?
Answer and explanation
Correct answer: Both play special roles in protection or heat balance
The governing concept is that a gas can have a small concentration but a major environmental effect. Ozone in the stratosphere absorbs much of the Sun’s harmful ultraviolet radiation, while carbon dioxide absorbs outgoing infrared radiation and contributes to the greenhouse effect and heat balance. Hence option B is correct; neither gas is most abundant, water vapour, or the main respiratory gas.
