Why is the sky blue????

Question

i meen why cant it be orange, red or green???

Answer 1

With pollution and global warming, it may be orange someday!

Answer 2

It's a little more complex than this, Jeff, but basically, the answer is this: Light contains the total spectrum of colors that can be seen by the human eye -- red, orange, yellow, green, blue, indigo & violet. Sometimes the sky will appear red, orange or yellow during sunrise or sunset, but appears blue during most of the daylight hours. This is because the atmosphere of the Earth filters out all colors during mid-day except one -- blue. During sunrise & sunset, the sun is seen at a sharper angle, and allows the red, orange & yellow to come through. Any help?

Answer 3

This question is asked at least 100 times a week on Y!A, and it is getting kind of old. Sixty years ago when I was in grammar school, we learned about why the sky was blue in about the third grade.

So go and find out for yourself. If your teacher does not know, (s)he needs to be kicked or something.

And it is not because the sky reflects the ocean. If the sky reflected the ocean it would be gray. All the people who post answers that say that the sky is blue because it reflects the ocean need to be boiled for about four hours. The sky is not reflective.

Answer 4

The sky is blue because the primary make-up is nitrogen which absorbs the other colors in the light passing the colors in the blue color frequencies. Oxygen is only about 18% of the atmosphere and passes green light green. The remaining gasses do not make up enough of the atmosphere to affect the color significantly. The color is determined by the amount of light in a particular frequency that reaches your eye.

Answer 5

the sky is really white,(think of a rainbow) when the sun hits the earth the blue rays reflect off particles in the sky causing it to be blue, when you see a sunset the sky can be orange red etc this is because shorter rays hit the particles making it orange etc.

Answer 6

The sky is blue because the sun reflects off the water in all the oceans and lakes and is a blue reflection.

Answer 7

The sky is blue, because the matter (including gases) that make up our atmosphere absorb the red end of the visible spectrum and scatter the shorter-wavelength blue end of the spectrum

.

Answer 8

A clear sky is blue from the ozone in the upper atmosphere.

That's the reason, These other guys are just shooting from the hip.

Hope you have lots of ozone in your upper atmosphere, not too much water or turbulence in the air between it and you, and a ground level temperature which you find amenable for light activity.

Answer 9

Because there are many particles of water and other materials in the air.

Wavelengths of light are colored according to how long they are. Because the sky has so many particles for wavelengths to bounce off of, the color of the sky is a short wavelength: blue.

Answer 10

Sometimes it IS th colors tht youve mentioned. It has to do with the time of day and dispersion of the visible light specturm throughout the course of the day. Blue light is refracted the most due to the earth's positioning.

Answer 11

The reflection of the ocean by the sun and since the ocean is red or anything like that the sky cannot be either
