Why is the sky blue

The sky appears blue during the day because of the way sunlight is scattered in the Earth’s atmosphere. When sunlight reaches the Earth’s atmosphere, it is made up of different colors of light. The short waves of blue light are scattered in all directions by the gases and particles in the atmosphere, making the sky appear blue to our eyes.
