|
because nitrogen and oxygen molecules scatter blue light more than the other colors
|
|
|
because the ocean reflects its blue color to the sky
|
|
|
because nitrogen and oxygen molecules scatter red and oranges away during the sunrise leaving blue for the day time

Detailed explanation-1: -Blue light is scattered in all directions by the tiny molecules of air in Earth’s atmosphere. Blue is scattered more than other colors because it travels as shorter, smaller waves. This is why we see a blue sky most of the time.
Detailed explanation-2: -In the lower atmosphere, tiny oxygen and nitrogen molecules scatter short-wavelength light, such blue and violet light, to a far greater degree than than long-wavelength light, such as red and yellow.
Detailed explanation-3: -Air molecules, like oxygen and nitrogen for example, are small in size and thus more effective at scattering shorter wavelengths of light (blue and violet). The selective scattering by air molecules is responsible for producing our blue skies on a clear sunny day.
