The sun's rays hit the Earth's atmosphere, where the light is scattered by nitrogen and oxygen molecules in the air. The blue wavelength of this light is affected more than the red and green wavelengths, causing the surrounding air to appear blue.
When sunlight travels through the atmosphere, blue light scatters more than the other colors, leaving a dominant yellow-orange hue to the transmitted light. The scattered light makes the sky blue; the transmitted light makes the sunset reddish orange.

This exhibit is a model showing why the sky is blue. This is a phenomenon called Rayleigh scattering. A clear tube is mounted in front of a light source with the light shining into the end of the tube. The light scattered by the tube looks blue near the projector and get progressively yellower further down the tube.
