What is the reason for the sky being blue? If its because of the water, what about the land not near water?

Answer 1

That is the way God made it.

Answer 2

The atmosphere is the mixture of gas molecules and other materials surrounding the earth. Visible light is the part of the electromagnetic spectrum that our eyes can see.

Light travels through space in a straight line as long as nothing disturbs it. As light moves through the atmosphere, it continues to go straight until it bumps into a bit of dust or a gas molecule.

The blue color of the sky is due to Rayleigh scattering. As light moves through the atmosphere, most of the longer wavelengths pass straight through. Little of the red, orange and yellow light is affected by the air.

However, much of the shorter wavelength light is absorbed by the gas molecules. The absorbed blue light is then radiated in different directions. It gets scattered all around the sky.

Which explains why the sky is blue.

Answer 3

The blue color of the sky is due to Rayleigh scattering. As light moves through the atmosphere, most of the longer wavelengths pass straight through. Little of the red, orange and yellow light is affected by the air.

Answer 4

This has to do with the scattering of light. It is a diffficult optics principle, but in a nutshell, light of the blue part of the ROYGVIB spectrum is scattered by airborne molecules more than red light, that gives sky its blue color. It is called Rayleigh scattering.
