Sky
From Wikipedia, a free encyclopedia written in simple English for easy reading.
The sky is what you see if you look up when you are outside. On earth, the sky usually looks blue when it is sunny, but it sometimes is orange, pink, red or grey and it is black at night. Some of the things people see in the sky are clouds and rainbows. Lightning can also be seen in the sky during storms. Birds, airplanes, and kites fly in the sky. At night, you can see beautiful stars that glow in the distance.
The sky also contains particles of dirt or dust, that float in the air. When the sun's light hit these particles, it would bounce off, so light wouldn't always be straight. The color blue from the sun is the color that bounces into many directions when it hits the gases in the air, such as oxygen and carbon. There is so many of them that it turns the sky blue, during the bright, sunny days.
The sun is in the sky. Because of the sun's light, the sea looks blue as well.
