A clear cloudless day-time sky is blue because molecules in the air scatter blue light from the sun more than they scatter red light. When we look towards the sun at sunset, we see red and orange colours because the blue light has been scattered out and away from the line of sight.

Blue light waves are shorter than red light wave and bend more when passing through our atmosphere. Red light waves are longer and don't bend as much. Sunsets are more red because the the blue scatters more through the atmospheric dust.
This is a very simplistic answer. Look up the previous answerer's reference for a more definitive answer.

Sunlight is scattered off the atmosphere. Look up 'Rayleigh scattering'.
It is NOT due to reflection off the ocean.
