It's not just a coincidence or a random choice by nature. The blue color of the sky is actually due to the way sunlight interacts with our atmosphere. As sunlight enters the Earth's atmosphere, it collides with molecules in the air, scattering the light in different directions. Blue light, with its shorter wavelength, is more easily scattered than other colors, giving the sky its characteristic blue hue. So next time you look up at the sky, remember it's not just a pretty color, but a fascinating scientific phenomenon.
