What similarity between carbon dioxide and water vapour is most important in climate study?
Answer and explanation
Correct answer: Both are linked with the greenhouse effect
Carbon dioxide and water vapour both absorb and emit infrared radiation, so both participate in the natural greenhouse effect that helps regulate Earth’s surface temperature. Their roles are not identical: carbon dioxide is a longer-lived, externally influenced forcing agent, while water vapour is highly variable and often acts as a feedback linked to temperature. Option A states the valid similarity; the other options incorrectly call them inert permanent gases or restrict them to the exosphere.
