Understanding Sky Colors

The video explores why the sky and sunsets display various colors. It explains that sunlight, which is white, is a mix of all colors. As it passes through the atmosphere, particles like gases, dust, and water droplets scatter the light, reflecting some colors and absorbing others. Clear skies appear blue because gases reflect blue light. Dust and moisture can dilute this blue, making the sky paler. Sunsets are red or yellow due to the long path sunlight travels through the atmosphere, which absorbs other colors. The video also includes questions to encourage deeper understanding.
