why is the sky blue???? i have the real answer to see if your right.?

Answer 1

My sister says it's the reflection of the ocean.
I think it is because when poeple need something to look to, they look at the sky. The sky is calming because it's blue. Blue is a calm color.

Answer 2

The sky is (roughly) that part of the atmosphere or of outer space visible from the surface of the earth (or any other planet; see Skies of other planets). Birds, airplanes, and kites are often considered to fly in the sky. It is difficult to define precisely for several reasons. During daylight the sky has the appearance of an opaque blue surface, but this is the result of the air scattering sunlight. [1]There is no "blue object" above the earth in any normal sense, so it is hard to say what object the sky is. The sky is thus sometimes defined as the denser gaseous zone of a planet's atmosphere. At night the sky has the appearance of a black surface or region scattered with stars. But if we then say that the sky is the entire visible universe, it would not be the same thing we see during the day. The color of the sky is a result of diffuse sky radiation. On a sunny day the Earth sky usually looks as a blue gradient — dark in the zenith, light near the horizon (due to Rayleigh scattering). It turns orange and red during sunrise and sunset, and becomes black at night.

Answer 3

Here is something interesting to think about: When you look at the sky at night, it is black, with the stars and the moon forming points of light on that black background. So why is it that, during the day, the sky does not remain black with the sun acting as another point of light? Why does the daytime sky turn a bright blue and the stars disappear?

The first thing to recognize is that the sun is an extremely bright source of light -- much brighter than the moon. The second thing to recognize is that the atoms of nitrogen and oxygen in the atmosphere have an effect on the sunlight that passes through them.

There is a physical phenomenon called Rayleigh scattering that causes light to scatter when it passes through particles that have a diameter one-tenth that of the wavelength (color) of the light. Sunlight is made up of all different colors of light, but because of the elements in the atmosphere the color blue is scattered much more efficiently than the other colors.

So when you look at the sky on a clear day, you can see the sun as a bright disk. The blueness you see everywhere else is all of the atoms in the atmosphere scattering blue light toward you. (Because red light, yellow light, green light and the other colors aren't scattered nearly as well, you see the sky as blue.)

Answer 4

The sky is blue partly because air scatters short-wavelength light in preference to longer wavelengths. Where the sunlight is nearly tangent to the Earth's surface, the light's path through the atmosphere is so long that much of the blue and even yellow light is scattered out, leaving the sun rays and the clouds it illuminates red, at sunrise and sunset.

God didn't do anything to the sky.

Answer 6

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.

The earth has a protective blanket of gases, water and dust called an atmosphere. The blue color of the sky is a result of sunlight passing through and interacting with the atmosphere.
If you look at sunlight through a prism, you will find that "white" sunlight is actually composed of a rainbow of colors.

Light can be described as a wave, and different colors of light correspond to different wavelengths. For example, red light has a long wavelength compared to blue light. As sunlight passes through the atmosphere, the atmosphere selectively filters blue light using a process called scattering. An example of scattering can be seen in a smoke-filled room. When light enters the room, the smoke particles scatter the light, resulting in shafts of visible light. The smoke particles, however, have little effect on the color of the scattered light.

Selective scattering (preferential scattering of one color of light over other colors) occurs when light scatters off particles that are much smaller than the wavelengths of the colors. In the case of our primarily nitrogen filled atmosphere, the shorter wavelengths (blue) are scattered much more strongly than the longer wavelengths (red). Thus, as sunlight passes through our atmosphere, blue light is preferentially scattered, and becomes visible to the eye

Answer 7

The sky is blue because the atoms in the sky scatter blue light in the atmosphere. That's for keeping it simple.

Answer 8

As light comes in from the sun, and hits the atmosphere, it diffuses, the blue rays fan out the furthest while all the others stay relatively closer together, except at sunset, which is because there's much more interference from denser air and air pollution, which makes EVERYTHING spread out the most, giving you the red and purple horizon.

Answer 9

this was taught in school when i was younger. im not so sure how it goes scientifically, but i remember it's cause of the color of the sea (which is blue) is reflected unto the sky and so the color of the sky is blue.

some smarta*s: so why does it turn orange at sunset/sunrise?
well, that's cause the sun is near. i dont know..

Answer 10

good question,
ive ask this quetion to myself many times and then took it upon myself to find the answer.

the sky is blue bcoz in the prism colors, blue refratcts the easiest. there for when the suns rays hit the earths atmosphere in its light is the prism. simple light refraction.

Answer 11

Well I'm not sure If I'm right or not, but a science teacher once told me, that there are different colors of light and the blue color is just the first ones to hit the earths atmoshphere.
