Which atmospheric phenomenon is caused by the scattering of sunlight by dust particles and gas molecules?

Correct answer: Blue color of the sky

Explanation: ✅ Correct Answer: B) Blue color of the sky 📚 Explanation: This phenomenon, known as Rayleigh scattering, occurs because shorter wavelengths (blue and violet) are scattered more efficiently by atmospheric molecules than longer wavelengths (red). Although violet is scattered even more than blue, our eyes are more sensitive to blue light, making the sky appear blue. During sunrise and sunset, the light travels through more atmosphere, leaving only the unscattered red light to reach our eyes.
