Answer 1

particles, particles, in the sky. Oh i wonder how stupid is that guy?

Answer 2

This is about the millionth time this question has been asked on here. Your mother is wrong. It appears blue because as sunlight enters the atmosphere a process called Rayleigh scattering occurs which affects the different colors of sunlight to differing degrees. The shortest wavelengths, blue and violet, are scattered the most. They bounce around and those that reach our eyes appear to be coming from all over the sky.
IT IS NOT THE REFLECTION OF THE OCEAN.

Answer 3

The white light from the sun is a mixture of all colours of the rainbow. This was demonstrated by Isaac Newton, who used a prism to separate the different colours and so form a spectrum. The colours of light are distinguished by their different wavelengths.

A clear cloudless day-time sky is blue because molecules in the air scatter blue light from the sun more than they scatter any other light.

Answer 4

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. Whichever direction you look, some of this scattered blue light reaches you. Since you see the blue light from everywhere overhead, the sky looks blue.

As you look closer to the horizon, the sky appears much paler in color. To reach you, the scattered blue light must pass through more air. Some of it gets scattered away again in other directions. Less blue light reaches your eyes. The color of the sky near the horizon appears paler or white.

Answer 5

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.

Answer 6

This is one of those eternal questions, like why are some people so stupid? You could teach the answer in school forever and some people would still ask. On the other hand, stupid questions are way better than believing stupid answers just because they're taught in school. Or church. Or on the street. Or on TV.

Answer 7

ok, everyone who answered is wrong. the air is mostly filled with hydrogen and methane. when either of these gasses are compressed very , very tightly they turn blue. they are blue gases. when they are compressed, only then will they turn blue. the earth is filled with these gases and therefore turned the sky blue. back in prehistoric time however, the sky was actually very,very light blue, almost white. eventually gases filled up and changed the colour. this is also why neptune and uranus is also blue.

Answer 8

Its the reflection of the sunlight on the atmosphere.

Answer 9

the sun reflects off the ocean's surface.
