Q:

why is the sky blue

A:

The sky is blue because of a phenomenon called Rayleigh scattering. 🌌

Here is the breakdown:

  • Sunlight is made up of all the colors of the rainbow.
  • As sunlight reaches Earth's atmosphere, it hits gas molecules and scatters in all directions.
  • Blue light travels in shorter, smaller waves, so it gets scattered more strongly than other colors, making the sky appear blue to our eyes. 💙

Fun fact: During sunset, the light has to travel through more of the atmosphere, scattering away the blue and letting the longer red and orange wavelengths through! 🌅
