Gases such as CO₂ and methane are considered greenhouse gases.This is because A)they are the most common in the atmosphere allowing them to trap more heat than the other gases. B)they form covalent bonds and hence can easily act as a shield for heat. C)the vibrational modes of the molecules are in the infrared region which imply that they readily absorb radiant heat thus preventing it from escaping into space. D)the gases are formed by human activity resulting in offsetting the natural balance in the gas concentrations. E)None of the above statements is correct.

Question

Quizplus · Accepted Answer

The vibrational modes of molecules of greenhouse gases such as CO₂ and methane are in the infrared region. This means that they can readily absorb radiant heat, preventing it from escaping into space. This is what leads to the warming effect often associated with greenhouse gases.
