why is the sky blue?

Answer 1

Nitrogen in the atmosphere.It's the correct answer. I've answered this question before and someone always gets picked as the best answer. This is the correct answer. Google it if you don't believe me.

Okay I'm tired of this you people are giving me thumbs down for a correct answer. Please people try and do some research on your own before sticking me with the thumbs down.

Go here and read what they say about nitrogen in the atmosphere. There oxygen molecules as well but we have a larger % of nitrogen in the atmosphere. If there were some other gas in the atmosphere the sky would be a different color.http://isaac.exploratorium.edu/~pauld/physics/why_is_sky_blue.html

Answer 2

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 3

the sky is blue because the sunlight reacts with the layers of the atmosphere and makes it look blue. That is why when the sunsets the sky turns black since there is no more light to turn it blue.

Answer 4

The sky is blue because the sunlight reflects the color of the ocean into the sky causing the sky to be blue

Answer 5

The refractive index of our atmosphere bends the sunlight.
For most of the daytime, we see only the blue beams.
At sunrise & sunset we travel first forward & then backward
through red, orange, yellow, green, blue, & purple.

The sky on Mars is red in the daytime; because their
atmosphere has less water & more dust.

Answer 6

Because blue light gets scattered more by the atmosphere.

Answer 7

This question is asked at least once a week here in YA, and there are a lot of good answers already written (if you search YA you'll find them).

Answer 8

Hi
I´m from ARgentina,
Well, the sky is blu because atmosphere has got ozone that to be in contac with ultraviolet radiation it makes a chemical reaction

Answer 9

the sky is blue from the eracction from the water:)

Answer 10

Sky is blue because it is natural.
