Its the same effect as shining light through a prism. Its all about wavelength and refraction

Here is something interesting to think about: When you look at the sky at night, it is black, with the stars and the moon forming points of light on that black background. So why is it that, during the day, the sky does not remain black with the sun acting as another point of light? Why does the daytime sky turn a bright blue and the stars disappear?
The first thing to recognize is that the sun is an extremely bright source of light -- much brighter than the moon. The second thing to recognize is that the 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.
So when you look at the sky on a clear day, you can see the sun as a bright disk. The blueness you see everywhere else is all of the atoms in the atmosphere scattering blue light toward you. (Because red light, yellow light, green light and the other colors aren't scattered nearly as well, you see the sky as blue.)

Idon't have a certain answer, but it's something about the sun and things like that.
but what i'm sure about is that it's not reflection of water. because the water is the one who reflects the sky, water is originally transparent but at the day it appears blue and at night it appears black, so it reflects the sky.
and the sky can't reflect anything because it's not a surface that can be reached, it's just the universe but we see it straight.
hope this helps in choosing the right answer.

On a clear cloudless day the 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.

The light rays of the sun Penetrates to the atmosphere. The blue light is more seen on days so the sky we see on day is blue. Thats why we see redish pink sky on midnights. Red is more seen at that time.
Hope this helps you..

The sky reflects off the waters of the ocean and that's why the sky is blue.

Oh and the sea reflects the sky not the other way around!

The sky is not actually blue it only apears that way it is a reflection of the water.
