Why is the sky blue?

Question

Don't come whit answers like:
"Thats the way God made it",or
"Thats the way it should be",
I want detalied answers, and clear because im not very good at English.

Answer 1

The sun sends blue and red razes to earth. The red razes are attracted by the ocean very much, so on the sky (our sky, from earth) remains only the blue razes. I know this from my teacher. Bellow is a site where you will find a lot more about your question.

Answer 2

THE SKY IS BLUE NOT BECAUSE OF THE OCEAN. For those of you who think this, think again and do some more research, using common sense doesnt work all the time. IT comes from the reflection of the sky and the air particles that the sun hits. First of all , light is rainbow, all sorts of colors added together making white light. The sunlight travels a short distance to the earth on noon, and that earth's atmosphere acts like a prism, and only the blue light can get in out of all the colors in the light (since the distance is short and blue has a short wavelength). THATS WHAT MAKES IT BLUE. Then on the sunset/sunrise side, it takes the light longer to get down to earth, because the sunrays are almost horizontal to the earth. When rays are horizontal, it takes them longer to touch the ground, thus, making the light rays long. The color RED/Orange has a longer wavelength so that's why you see a red or orange sunset/sunrise.


Main point: THE OCEAN HAS NOTHING TO DO WITH THIS

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.

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.

Answer 4

Many theories. Mine: particles in the air make the sky appear blue, not the reflection of the ocean.

Answer 5

its simple
see the light spectrum is of seven colurs VIBGYOR
when sunlight ,
1. is yellow in colour
and
2.yellow=blue+green
falls on earth
there is little green the ocean and water body form the bulk area of earth
hence whats left = blue
hence blue ocean reflect blue colour which is reflected by the clouds in the sky

Answer 6

The bonding angle between nitrogen molecules backscatters best at around 470 nm (which is in the blue part of the spectrum).

Answer 7

It is blue because the sun's light reflects of the ocean making the sky blue.

Answer 8

The sky is blue, because of water crystals in the atmoshpere reflect the color of the ocean.

Answer 9

b/c it reflects off of the oceans.

Answer 10
