Blue sky: a more detailed explanation
Light is made up of electromagnetic waves.
The distance between 2 crests in this wave is called the wavelength.
White light contains all the colors of the rainbow.
The amount of light scattered for any given colour depends on the wavelength of that colour.
All the colors in white light have different wavelengths.
Red light has the longest wavelength.
The wavelength of blue light is about half that of red light.
This difference in wavelength causes blue light to be scattered nearly ten times more than red light. Lord Rayleigh studied this phenomena in detail. It is caused the Tyndall effect or Rayleigh scattering.
Lord Rayleigh also calculated that even without smoke and dust in the atmosphere, the oxygen and nitrogen molecules would still cause the sky to appear blue because of scattering.
When blue light waves try to go straight through an oxygen and nitrogen molecules, its light is scattered in all directions because of this collision.
This scattered blue light is what makes the sky blue.
All other colors (with longer wavelengths than blue light) are scattered too.
Blue light's short wavelength causes it to be scattered the most.
(The shorther the wavelength of the color, the more that color gets scattered by the atmosphere)
Actually, violet has the shortest wavelength of all colors. Violet is scattered even more than blue light. However, our eyes are much more sensitive to see blue than violet, therefore we see the sky as blue.
Very little visible light is absorbed by the atmosphere.

the sky is blue due to the sea (something like that)
space is black because its empty and theres no light, therefore blackness...why black and not pink or something, no one will know.
sun is yellow because it burns
clouds are white because of water vapour

Ok what makes the sun burn
What is its fuel to burn forever
Did Danial J set fire to it in the begining

isn't the sky blue due to there being more nitrogen or some other gas?
and it isn't the reflection of the sea. other way around. although scientists have proven that water is now not clear but has a slight blue tint to it.

we're closer to the centre of the earth which is warm and we are below clouds. clouds keep warm air in. higher up you go, the less clouds

thats because the sun heats the ground and air, and the higher you go the less air there is to heat (and less ground obviously)
edit: and like gold said, clouds too

big ball of gas
Why doesnt it burn itself out
Its been burning for thousands of years - surley it will run out of gas at some point

it does burn out eventually.
when i said big ball of gas... i meant BIG
sommat like another 100 million years to burn out iirc
