Hi! Welcome back to the Kids Answers magazine blog, where we answer your big questions about God’s Word and God’s world.

How are you today? We hope you’re not feeling blue!

Have you ever wondered why the sky is blue and not orange, green, or some other color?

Light travels from the sun in colorful waves. The waves are all the colors of the rainbow—red, orange, yellow, green, blue, indigo, violet. The waves of light hit gases and particles as they travel through our atmosphere, causing the waves to scatter. Blue light travels in short, choppy waves and gets scattered more than the other waves of light. This is why the sky looks blue! If all the waves of colored light scattered evenly, the sky would appear white to our eyes.

God’s creative handiwork is on display everywhere—even way up in the brilliant blue sky on a sunny day.

What About Clouds?

Clouds are made from water droplets and ice particles. When the waves of light from the sun hit these particles in clouds, they scatter evenly, causing the cloud to look white. Clouds thicken before a storm and sunlight is blocked from traveling through the cloud. That’s why rain clouds look gray.
