Why was sky are blue

Answer» 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.
And another is a large part of earth is covered with water and it is in blue colour so light reflected from it colours blue that\'s why sky appear blue
Because blue colour is the less dispersible colour in refraction of atmosphere
