Answer 2

The colour of sky is blue due to scattering of blue light most by the air particles . As blue light has an optimum wavelength so is scattered most.

The water of sea is salty because water reaches the sea after travelling various surfaces which contains many types of mineral salts some of which sweep away with the running water making it salty.
