Question

Carbon dioxide causes global warming as it traps .

• A. heat
• B. nitrogen
• C. water vapour

Answer 1

The correct option is A heat

Global warming is the rise in the average temperature of Earth's climate, over a long time period. This is mainly caused by various greenhouse gases present in the atmosphere.

Greenhouse gas absorbs the infrared radiations from the Sun and traps heat, thereby increasing the temperature of the Earth. Carbon dioxide being a greenhouse gas traps heat. Hence, it contributes to global warming.
