Why is the sky Blue?

Light passing through a prism is broken up into its spectrum. Light passing through the atmosphere is scattered similarly, all the frequencies being absorbed on their way through the billions of air and water molecules, leaving the particular wavelength that makes you think you are seeing blue.
