Color in light is actually wavelengths, and the sunlight has different colors of lights. The sky looks blue because of "Rayleigh Scattering." You see, light scatters when it passes through particles that are 10% the diameter of the wavelength. The blue color in the Sunlights wavelenghts scatters better than the other colors. So we see blue.
This is also why the sky is black, because there is no sunlight, so its blue wavelengths aren't being scattered in the atmosphere.

The sky looks blue from earth because of the scattering of sunlight by the atmosphere. Blue light is scattered more and hence sky looks blue.

Rayleigh scattering of course. That is to say more of the blue wavelength is scattered than the rest of the visible spectrum. Since the shorter blue wavelength is scattered the sky appears blue.

Well...the light from the sun coming through our atmosphere is refracted by water crystals and material in the sky. The blue part of the spectrum is absorbed, the color that is radiated is the same color that was absorbed. the rest gets filtered through/reflected and refracted. That's why the sky is blue. =)
And yes, it's called Rayleigh scattering. =)

Because the sunlight is reflecting off the water. Remember that Earth is mostly water.
