Sky
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. People also say that birds, airplanes, and kites fly in the sky.This article is a stub. You can help Wikipedia by adding to it.
