10 Astonishing Facts About Why the Sky Looks Blue (And Sometimes Red!)

3. Atmospheric Particles - The Role of Dust and Pollution

The presence of dust, pollutants, and other particles in the atmosphere can significantly alter the sky's color. These particles scatter light differently than the gases responsible for Rayleigh scattering, often enhancing the reds and oranges seen during sunrise and sunset. In areas with high pollution levels, the sky can take on a more muted or even brownish hue. Conversely, after a rainstorm or in pristine environments, the absence of these particles can lead to more vibrant blues. The interplay between atmospheric particles and light scattering underscores the delicate balance required to produce the sky's ever-changing colors, highlighting the impact of human activity on this natural phenomenon.
