Which statement correctly analyses the roles of atmospheric gases?
Answer and explanation
Correct answer: Nitrogen, oxygen, carbon dioxide, and ozone have different roles
Atmospheric gases have distinct functions. Nitrogen is important in the nitrogen cycle and dilutes oxygen; oxygen supports respiration and combustion; carbon dioxide is used in photosynthesis and influences Earth’s heat balance; and ozone absorbs ultraviolet radiation. Water vapour also affects clouds, weather, and heat transfer. Therefore option B is correct, while the other statements wrongly treat gases as having identical or unrelated roles.
