blue sky is formed from the scattering of light by air particles.
white light consists of many coloured lights, such as red , orange,
yellow , green, blue, etc.... when white light pass through the
earth at an angle, different colour of light scatter differently,
so somewhere in the earth will see blue colour,
somewhere in the earth will see orange colour.
