Which trace gas in the atmosphere plays a significant role in the greenhouse effect?

  1. Oxygen
  2. Nitrogen
  3. Carbon dioxide ✓
  4. Argon

Explanation

Carbon dioxide traps heat in Earth’s atmosphere. It acts like a blanket. More CO₂ means warmer planet.

Oxygen and nitrogen are common but don’t trap heat. Argon is an inert gas. Only greenhouse gases like CO₂ and methane trap heat.

Remember: CO₂ levels are rising from burning fossil fuels. This increases the greenhouse effect.
