the sky is blue because of the way light refracts off of our ozone layer.Just saw a special column in Discover magazine yesterday about this very subject.Leonardo Da Vinci was actually the first person to come up with the answer on why it was blue.

Answer 3

B/c blue has a shorter wave length than red but a longer wave length than purple. So it is difused by the earth's ozone shield. Making the sky appear blue.

Answer 4

The light from the sun is composed of "every color in the rainbow". But with our atmosphere, most get scattered, except the blue light, which comes in the strongest.

As the sun get closer to the horizon, more and more blue light gets scattered, and the reddish lights shine through.

Rayleigh scattering. I don't know what it means even after learning about it numerous times.

Wikipedia will tell you more than you would ever want to know about the topic.
