Dancing molecules (How greenhouse gases work)

[Source: All About Climate YouTube channel]

Why do greenhouse gas molecules vibrate with radiation?

(Skip this part if you're in middle school).

How do greenhouse gas molecules deform this way?

Return to the simulation: activate Sign of charges to visualize the signs of partial charges in the molecules, and activate Electric field to visualize electric field vectors ($E$ ) along the electric waves.

Click Play. Then, when the radiation reaches the molecules, Pause and advance step by step (double arrows).
