WHY IS THE SKY BLUE?
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.
As you look closer to the horizon, the sky appears much paler in color. To reach you, the scattered blue light must pass through more air. Some of it gets scattered away again in other directions. Less blue light reaches your eyes. The color of the sky near the horizon appears paler or white.

What do you mean by dispersion?

Sky is seeing blue because the dispersion of light due to the water of sea.

The water is colorless and also odourless.

I am collapsed with the answer.
Dispersion of light because in some other websites the answer is scattering of light please say which one is correct.

Scattering is the right answer.
But here dispersion may be chosen as no option for scattering.
