The sky is blue due to the refraction and reflection within the sky and movement of sunlight through the air. Blue wavelengths are reflected out and our eye picks them up. Light penetrates and "scatters" in the atmosphere, bouncing off of individual particles of atoms, smashing through vapor droplets removing or absorbing the other colors leaving blue to reach our eyes. of course that is only a fraction of the sunlight, most of it makes its way straight down to bound off and be absorbed by other materials depending on what colors those materials absorb and reflect determines what color we see from any given material. Remove the light you remove the color. Although the sun does not stop shining, the earth does turn and the night side is the shadow side from the sun. During the night the shadow prevents sunlight from hitting the atmosphere. On some full moon nights around the moon you can see a slight bluish tint. In this case sunlight bounces off the moon and the reflected light has a much smaller affect on the atmosphere.

sunlight reflect off the water and into then sky or some nonsense...

Certain gases in the atmosphere mix to create the "blueness" of the sky.

The sky is blue because 75% of the world is covered by ocean. The blue that you see in the sky is the reflection of the ocean. The sky is like a giant mirror. The reason why the ocean is blue is because the visible light the sun outputs is every single color when the light passes through the atmosphere blue is filtered through. If you went into space and looked at the sun you would not see yellow but white although you shouldn't because if you think the sun causes eye damage on earth imagine looking at it without a filter.

It's not! It really has no color. The sun bounces off the water molecules in the atmosphere to make it appear blue.

If you get out into the space, you will see the sky black.Because sky is in reality just a space. The reason why it appears blue is based on Rayleigh's scattering law, stated as below: "The amount of scattering is inversely proportional to the fourth power of wavelength" The white light is made of VIBGYOR(Violet,Indigo,Blue,Green,Yellow,Orange and Red) colours and the above statement means that those with smaller wavelengths are scattered more, which in this case is the violet end of the spectrum.(Probably if you know these). So you may argue that the sky should appear violet.But it happens that the wavelength of violet and indigo are too large that it is completely scattered away.So only the blue spectrum reaches our eyes since it is scattered(i.e,spread) more than the other colours.

Tyndall effect. It has to do with the way the atmosphere disperses sunlight. White light contains all colours, but the way it is split my our atmosphere, it is the blue that is most visible. To recreate it, pour a glass of water and add a teaspoon of milk to it. Then turn out the lights and shine a flashlight into the side to the glass. You'll notice a faint bluish glow. The milk in the water acts, on a small scale, the same way the gases and things in our atmosphere do. It's hard to explain, do the experiment and you'll see what I mean.

It is because blue light from the sun strikes the air molecules and scatters and our eyes perceive it as blue.

white light is scattered by the earths atmosphere and the wavelengths scattered the most correspond to those of the colour blue. when the sun is low in the sky it appears more red because the atmosphere at these angles allow longer wavelength photons to be scattered

We all know where you got that question but I'll tell you. It's because light reflects off of the water droplets in the sky.

Because it says so in the book of the bereft

the creator ran out of green :)

because, God ran out of green! (lol)!

Because that's why, now stop bothering me and go play. At least that was what my mother said....

It just looks blue, its really pink and gray.

I find it so much prettier than green

A clear cloudless day-time sky is blue because molecules in the air scatter blue light from the sun more than they scatter red light. When we look towards the sun at sunset, we see red and orange colours because the blue light has been scattered out and away from the line of sight.

It reflects off the sea - if the world were covered mostly in land, the sky would be green - beautiful, isn't it?

What makes you think its blue?

http://www.sciencemadesimple.com/sky_blue.html 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.

The right answer would be because the color of light that filters through all the dust the wave form is what we see as blue... sometimes if you notice you see the sky as gray (when there are clouds) black (when there's no light), orange/varitions of pink) when the sun is angled correctly during sun rise or sun set... the light filters through at a different angle giving different colors... The wrong answer is... the sky is blue because she is sad... Sky goddess Nut, is forced to stay away from her Brother-Husband Geb. She was shown in Egyptian artwork as a dark, star-covered naked woman, holding her body up in an arch, facing downwards. Her arms and legs were imagined to be the pillars of the sky, and hands and feet were thought to touch the four cardinal points at the horizon. Far underneath her lay the earth god, Geb, sometimes ithphallyic, looking up at his sister-wife. She was also described as a cow goddess, taking on some of the attributes of Hathor. Geb was described as the "Bull of Nut" in the Pyramid Texts. As a great, solar cow, she was thought to have carried Ra up into the heavens on her back, after he retired from his rule on the earth. She was even been depicted as sow, or with the teats of a sow, ready for her children to suckle.

because it is dark at night

it's blue? All this time I thought it was pink! crap!

Well, Dude, I believe you just answered your own questionl. Because it reflects the oceans!!

The skys actually black...The earths atmosphere is full of particles like dust which, when the light reflects off them, makes the sky appear blue. When its night, no sun= no light= black sky.

you cants see colour without light so if its dark you cant see blue

because it turns black at night

Black, if there were no reflection or refraction in the air. You would just see outer space. Note that this is the color of the "sky" on the Moon.

probably transparent, like water. if there is dye or particle in water, then it would a ppear a certian color or liquid. but in its pure form, it is transparent

its the reflexion from the ocean.

Rayleigh scattering -- air molecules scatter blue light from the sun, but not the longer wavelengths. That the blue color is related to reflection from oceans is an erroneous myth. [edit] Why not at night? Because there is no light source -- blue or otherwise. In principle a strongly lit moon should scatter a little blue moonlight to give the sky a dark bluish cast.

the sun reflects the sea and at night it dosent

the sky has to be blue in the day if it was at night no one would go to sleep

Colors are either light waves that are being reflected off an object or being reflected onto something from elsewhere. No light - no color; no blue sky, no red apple; nothing. White are all colors and black is not a color - there is nothing being reflected; so how can you see a black object during the day? +5 just because.

The ocean blue color reflects off the sky!!

BECAUSE MY DICK LIKES IT LIKE THAT

Because at night, he gets to go out and have fun.

BECAUSE IS REFLECTS OFF THE BLUENESS OF THE OCEAN!!!! ......AND BCAUSE ITS LIGHT OUT, LOLZ LOLZ LOLZ LOLZ LOLZ LOLZ LOLZ LOLZ LOLZ LOLZ LOLZ LOLZ LOLZ LOLZ LOLZ........AND SO ON IF U GET IT

5-24-2017 Hey, are you the one who shut yourself in an icebox to see if the light went out when the door was closed, and then couldn't tell because it was too dark?

Because blue light is reflected back from the atmosphere during daylight hours when the sun provides the light source.
