Have you ever wondered why the sky looks blue? Let's find out step by step!
1. The Sun Sends Light to Earth
The light from the Sun looks white, but it's actually made up of many colors all mixed together, like a rainbow.
2. Earth's Atmosphere
Our Earth is surrounded by a layer of air called the atmosphere. This atmosphere is filled with tiny gas molecules.
3. Light Hits Air Molecules
When sunlight enters the atmosphere, it bumps into these tiny gas molecules. Different colors of light behave differently when they hit the molecules.
4. Blue Light Scatters More
Blue light waves are shorter and smaller, so they scatter, or spread out, more than other colors when they hit the air molecules. This scattering causes the blue light to spread across the sky in all directions.
5. Our Eyes See a Blue Sky
Because blue light scatters everywhere, when you look up at the sky, you see it as blue!
So the reason the sky is blue is that the blue part of sunlight gets scattered more than other colors by the air around us.
