The air gets warm when the Sun shines on Earth. Explain how that happens.
- Some of the Sun's radiant energy is absorbed directly by gas particles. - Radiant solar energy also strikes Earth's surface; soil and water absorb the energy. - Particles in Earth's surface materials increase their motion (they heat up). - Particles of gases in the air come into contact with Earth's heated surfaces. If the surface is warmer than the air, energy transfers from surface to air by conduction; air particles increase their motion (they heat up).
