I've always wondered...

Question

...why is the sky blue?

Answer 1

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.

Rayleigh Effect

Answer 3

reflection of the ocean on the gases in the atmosphere

Answer 4

a chemical compound in the atmosphere makes the sky blue ( I have no idea wat the chemical coumpound is)
