The sky appears blue due to a phenomenon called Rayleigh scattering. 🌌

Here is the quick 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 is scattered more strongly than other colors, making the sky look blue to our eyes. ☀️💙

The sky appears blue due to a phenomenon called Rayleigh scattering. 🌌

Here is the quick breakdown:

• Sunlight: Sunlight is made up of all the colors of the rainbow. 🌈
• Atmosphere: As sunlight reaches Earth's atmosphere, it collides with gas molecules and scatters in all directions.
• Wavelengths: Blue light travels in shorter, smaller waves, so it gets scattered more strongly than other colors, reaching our eyes from every part of the sky. 🔵

When the sun is low (sunrise/sunset), the light has to travel through more atmosphere, scattering away the blue and leaving the longer red and orange wavelengths to reach us! 🌅
