Question 22

A scientist investigates how three gases interact with radiation emitted by a warmed surface.

The results are shown in the table.

GasLong-wavelength radiation entering the gas in arbitrary unitsRadiation detected above the gas in arbitrary unitsRadiation emitted by the gas towards the surface in arbitrary units
Gas A1006535
Gas B1007228
Gas C1006040

Use the data to explain why each gas can contribute to keeping Earth's surface warm. Predict what would happen to the average surface temperature if the amount of one of these gases in the atmosphere increased.
