Attempt this previous-year question. The correct option stays hidden until you choose.
Consider the following statements:
I. Without the atmosphere, temperature would be well below freezing point everywhere on the Earth’s surface.
II. Heat absorbed and trapped by the atmosphere maintains our planet’s average temperature.
III. Atmosphere’s gases, like carbon dioxide, are particularly good at absorbing and trapping radiation.
Which of the statements given above are correct?
Pick an option to check yourself.
• Correct Answer: C
• Without atmospheric greenhouse effect, Earth's average surface temperature would be ~-18°C, below freezing.
• Atmospheric gases trap outgoing long-wave radiation, maintaining average temperature at ~15°C.
• CO2, methane and water vapour are efficient greenhouse gases absorbing infrared radiation.
