why is the sky blue?

Question

i have herd soooo much on this topic, but witch ones true?

Answer 1

will the earth is covered by approx. 72% water and the light reflecting of the water is what gives the sky its blue color.

Answer 2

this is because 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 3

Light coming from the sun is what's called "white light" White light contains all the colors of the rainbow. When it enters Earth's atmosphere this light is separated into its individual colors by chemical elements in the atmosphere and scattered across the sky. Nitrogen is the most abundant element in our atmosphere, and that element scatters the color blue across our sky more than the other colors. In space, there is no atmosphere to separate colors from the white light and space looks black.

Answer 4

People go day in and day out trying to figure it all out...it doesnt make since to live life asking questions that are unanswerable, such as this one....try to figure out ways to feed our ppor, put our homeless in homes, feed our starving americans not self minded questions...or jsut keep asking why is pink called pink or why is dirt called dirt and not called grass, the easiest answer to your question is becasue you were brought up to look at the sky and say its blue not green so thats why it is blue becasue everyone says it is and becasue until you can prove blue is really green or purple is really orange then these quesitons are senseless.

Answer 5

The sky is clear. No matter where you go, if you bottle up some sky and bring it back with you, it will be clear.

However, looking up to LIGHT through a whole LOT of sky will cause the light to bend through the air particles and appear blue.

Answer 6

as the original beam of sunlight passes through the atmosphere, its intensity decrease as its energy goes into the scattered light. details analysis of the scattering process shows the intensity of the light scattered from air molecules increases proportional to the fourth power of the frequency.thus the intensity ratio for the two ends of the visible spectrum is (700nm/400nm)^4=9.4.roughly speaking,scattered light contains nine times as much blue light as red, and thats why the sky is blue.

Answer 7

Because if it was green we wouldn't know where to stop mowing! Just kidding, it is the refraction of light and the absorbsion of the blue part of the spectrum by oxygen that does it.

Answer 8

The sky is blue b/c the water in the ozone layer reflects blue color so we see it as blue.

Answer 9

All the gasses in the sky mix together to make a bluish color. =^.^=

Answer 10

The atmosphere makes it blue.
