why the sky is blue?

Answer 1

Since no one has got this right yet...geez. NO ITS NOT REFLECTING THE OCEANS. The blue color comes from a refraction effect called Rayleigh Scattering. Basically when light passes through the atmosphere at higher angles (during the day) the redder spectrums of light are refracted away from the viewers (us), leaving us with more blue lightwaves making it to our eyes, so the sky looks blue. At sunrise and sunset the angles are different, as well as the light has to pass through more atmosphere, and because of this most of the blue light is refracted away from the viewer again, but it results in the nice redder spectrum colors you see at those times of day.

And to Clive: I think it more than explains why...variations in atmospheric thickness for one, viewing angle for another. Maybe you just dont understand how it works.

Answer 2

Light is a kind of energy that can travel through space. Light from the sun or a light bulb looks white, but it is really a mixture of many colors. The colors in white light are red, orange, yellow, green, blue and violet. You can see these colors when you look at a rainbow in the sky.

The sky is filled with air. Air is a mixture of tiny gas molecules and small bits of solid stuff, like dust.

As sunlight goes through the air, it bumps into the molecules and dust. When light hits a gas molecule, it may bounce off in a different direction. Some colors of light, like red and orange, pass straight through the air. But most of the blue light bounces off in all directions. In this way, the blue light gets scattered all around the sky.

When you look up, some of this blue light reaches your eyes from all over the sky. Since you see blue light from everywhere overhead, the sky looks blue.

Answer 3

The sun gives off white light, light is made up of an equal amount of green, red and blue. When light hits our atmosphere the angle in which the light hits it causes red and green to pass through but blue bounces off at a different angle causing the sky to be a stained blue colour. All of the light comes through but blue bounces to a certain extent before coming through the atmosphere.

Answer 4

the blue color of the sky is by Rayleigh scattering. As mild strikes for the time of the ambience, a super sort of the longer wavelengths bypass on the instant by. Little of the purple, orange and yellow mild is laid low with the air. regardless of the undeniable fact that, maximum of the shorter wavelength mild is absorbed by ability of the gasoline molecules. The absorbed blue mild is then radiated in diverse guidelines. It gets scattered all over the sky. Whichever direction you look, a number of this scattered blue mild reaches you. considering the fact which you notice the blue mild from everywhere overhead, the sky looks blue.

Answer 5

The sun's rays hit the Earth's atmosphere, where the light is scattered by nitrogen and oxygen molecules in the air. The blue wavelength of this light is affected more than the red and green wavelengths, causing the surrounding air to appear blue. At sunset, the sun's light passes farther through the atmosphere, deflecting and decreasing the blue in the air. Scattering by dust particles and pollution in the air causes the sunset to appear red.

Answer 6

because the sky is actually just white light that the sun produces. but when the white light hits large bodies of water it would reflect back into the sky which makes the sky appear blue to the human eye.

Answer 7

The sky reflects the colour of the sea; blue ie one of the seven colours of the rainbow with the light given by the sun.. Thats why it is blue. In the night sky there is no sun so we cant make out the colour.

Answer 8

the sun reflects on the oceans and seas at day time, the reflection makes the sky blue. At night there is no sun only moon and the moon is to little to light the sky.

Answer 9

It isnt blue just appears to us to be blue. In fact it is black like on a clear night looking into space, the things that makes it appear blue is the layers above the earth just reflecting the water which covers 2 thirds of the earths surface.

Answer 10

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.
