Q1 5.9 Chemistry of the atmosphere

Earth’s surface absorbs radiation and emits infrared radiation. How do greenhouse gases contribute to warming?

  1. They prevent all sunlight from reaching Earth.
  2. They absorb and re-emit some outgoing infrared radiation.
  3. They convert infrared radiation into oxygen.
  4. They remove heat by reflecting every wavelength into space.
Show the answer and explanation

Answer: B. Greenhouse gases absorb and re-emit infrared radiation, reducing the rate at which energy escapes to space.
