What is the primary mechanism of the 'Greenhouse Effect' in terms of molecular physics?
AGas molecules reflecting all sunlight
BVibrational/rotational modes of triatomic molecules matching infrared frequencies
CThe high density of greenhouse gases
DThermal conduction between gas molecules
✓ Correct Answer: B — Vibrational/rotational modes of triatomic molecules matching infrared frequencies
Molecules like CO2 and H2O have 3 or more atoms and can vibrate/rotate in ways that absorb infrared photons.
