The following site explains in detail:

FYI the sky isn't blue because of light reflecting off the oceans. The blue color of the sky is due to Rayleigh scattering. As light moves through the atmosphere, most of the longer wavelengths pass straight through. Little of the red, orange and yellow light is affected by the air.

However, much of the shorter wavelength light is absorbed by the gas molecules. The absorbed blue light is then radiated in different directions. It gets scattered all around the sky. Whichever direction you look, some of this scattered blue light reaches you. Since you see the blue light from everywhere overhead, the sky looks blue.

Answer 2

Actually the color of sky is black. Sun light get reflected on dust particles in enviorenment, overall it produces sky blue color.

Answer 4

Becasuse its too far away from the earth. The radiation of the atmospheric pressure and the vapoour of the water makes feel that the sky is blue.

Answer 5

Light scatters at different wavelengths, creating the colors of the rainbow that we can see.  Green has one wavelength, while blue has another.  Since the atmosphere is gas molecules, when light enters the atmosphere, longer wavelengths pass through, but blue has a short wavelength and is therefore absorbed by the gas molecules.  The blue light then scatters everywhere you see except closer to the horizon, where it looks less blue and this is because the light has to go through more air to reach you.

Answer 6

sun light is consist of many colors . Earth is covered of moisters & watar   molecules when sunrays go through this atmosphere, its consistence get spilt .And blue color amongs them shows max. vizuility, which gives certain results.

  

Answer 7

Water in the air reflects light from the sun, so it looks blue.
