Why is the sky blue?

Answer 1

the ocean makes it blue

Answer 2

The colour of the sky is a result of diffuse sky radiation and the fact that air is actually a very transparent blue color[1]. On a sunny day the Earth sky usually looks as a blue gradient — dark in the zenith, light near the horizon (due to Rayleigh scattering). It turns orange and red during sunrise and sunset, and becomes black at night.

Sky luminance distribution models have been recommended by CIE (the International Lighting Commission) for the design of daylighting schemes. Recent developments relate to “all sky models” for modelling sky luminance under weather conditions ranging from clear sky to overcast sky[2].

The color of the sky appears to be blue because the atmosphere scatters shorter wavelenght light (blue and violet) more than longer wavelength light (red), and thus we see more of the scattered blue light.

So it isn't actually blue its just how we see it due to how the atmosphere deals with light. That is also why at sunset it can seem red, yellow or orange or various other colours. Or why at night when there is no light it seems to be black.

Oh and that thing about reflecting of the ocean... Well then why does it change colour as mentioned at sunset etc? And why is it blue thousands of miles inland where there is no ocean or large water mass for it to reflect off?

The ocean thing is something adults tell children as they cant be bothered to explain it properly.

Answer 4

Atoms of nitrogen and oxygen in the atmosphere have an effect on the sunlight that passes through them.

There is a physical phenomenon called Rayleigh scattering that causes light to scatter when it passes through particles that have a diameter one-tenth that of the wavelength (color) of the light. Sunlight is made up of all different colors of light, but because of the elements in the atmosphere the color blue is scattered much more efficiently than the other colors.

Answer 5

according to rayleigh's scattering law,the wavalength of blue is ideal for refracting and blue colour gets refracted more than any other color and the sky appears blue for us

Answer 6

The light from the sun is refracted in the Earth's atsmophere, the same way you can see a rainbow refracted in a prism. But since blue is the strongest color of that refraction that is the color we see.

or something like that.

Answer 7

the sky isnt actually blue.
it is just a reflection of the ocean. 70% of the world is full of water and it covers most of the earths surface so therefore it reflects the ocean. also, the rain, when it is about to precipitate the clouds are grey which actually shows its full of liquid water. when the clouds are white, they show theyre no longer dragged by water. hope that answers your question.

Answer 8

the sky actually is not blue . its appears to be blue because that is as far as your eyes can see . you are not seeing anything ,

Answer 9

It wont be blue when it rains or at night. So it's blue because of the sunlight and even then, only when there are no clouds.

Answer 10

it reflects off the ocean.
