Greenhouse Gas Science

Describe the electromagnetic spectrum and distinguish between short-wave solar radiation and long-wave infrared radiation emitted by Earth; explain how greenhouse gas molecules (CO2, CH4, N2O, H2O) absorb and re-emit infrared through molec…

Question 1 of 3

A scientist draws a simple electromagnetic spectrum with three wavelength sections: 1) 0.2 µm – 0.5 µm 2) 5 µm – 15 µm 3) 30 µm – 100 µm She needs to label each section as either “short‑wave solar radiation” (radiation coming from the Sun) or “long‑wave infrared radiation emitted by Earth.” Which label sequence is correct?

Question 2 of 3

You have six cards, each labeled with a gas: CO₂, CH₄, N₂O, H₂O, O₂, and N₂. Which answer correctly puts all gases that can absorb Earth’s infrared radiation in one group and the gases that cannot in the other group?

Question 3 of 3

Which statement best reflects the scientific evidence about the Earth's climate cycle?
