Why We Feel the Sun's Warmth Despite Its Distance
The Sun is 93 million miles away but emits vast electromagnetic radiation (visible light, UV, infrared). Photons travel through space and interact with skin atoms, increasing molecular vibration and generating heat. Factors affecting perceived warmth:
- Radiation intensity
- Time of day (direct overhead = more concentrated rays)
- Weather and atmospheric conditions (clouds, dust scatter radiation)
The Sun's immense power and constant photon stream allow its warmth to reach Earth across vast distances.
