You would think at "my" age, I would know "why" the sky is blue, but I don't. I'll be right back................................

Okay, I'm back. Well, I asked chicken little, and he said he didn't know either,and "all" he was worried about was that the darn thing was falling! Sorry, I got ahead of myself, and I honestly don't know the answer. Good luck though.

Nearly right, Manny.
The shorter wavelengths are "scattered" by all manner of tiny particles in the atmosphere, not by the gas molecules themselves. This light (& UV) goes off in all directions and some comes back at us. Hence a clear sky is blue and why you can get a suntan from a blue sky.
Remove a little blue from the spectrum of a nearly white source (i.e. our sun) and it appears yellow. Remove a bit more (e.g. at sunrise/sunset when the light travels a greater distance through the atmosphere to reach us) and it appears orange. Add a load of dust in the air, for whatever reason, and the sun appears red and the sky is a more intense blue.

The sky is blue, because sunlight is diffused in the atmosphere. Blue light has has a shorter optical path length (around 49 km/30.6 miles) than red light (around 180 km/112.5 miles). Therefore, the diffusion process of blue light is more efficient. On the other hand, sunrise and sunset are red because light has to cover a longer distance through high-density areas within the atmosphere. Blue light is substantially diffused, so the sky turns red.

I may have this the wrong way round but I think it is reflected off the ocean, but its more scientific than that, it's something to do with the light prisim, u know the colours of the rainbow, well for some reason the light that hits the ocean or something results in only they colour blue, im sure someone will tell me thats absolute bollocks though if so sorry, but its what i heard!x

When transmitted light such as sunlight enters our atmosphere it collides with the oxygen and nitrogen atoms. The color with the shorter wavelength is scattered more by this collision. Because violet and blue are the shortest wavelengths the sky appears to be violet / blue. But because our eyes are more sensitive to blue light than they are violet light, we perceive the sky as blue.

because bodies of water are blue and the water reflects on it. the atmosphere and light scattering also make the sky look blue, too.

It's the colour of air. When we look at the sky we look at thick layer of air, which is very slightly bluish.

the sky is blue- because it is the most prominent colour of the spectrum in the athmosphere. it has nothing to do with the colour of the sea, esp as water is not blue!!!!!!!!!!!!!!!

The sky isn't actually blue - it is in fact black - the suns rays reflecting off the ionosphere make it appear so.
