The sky's blue color is caused mainly by the... (multiple choice)?
or
b. scattering of sunlight by gases in earths atmosphere
or
c. refraction of sunlight by earths ionosphere
help thanks
Answer:
b
b.
Rayleigh scattering
c
c
c sounds good
B
b
b...specifically Rayleigh scattering
Technically the sky is blue to humans because it looks blue in the wave length of light that our eyes and brains see. Birds and insects for example see colors differently than humans. Because of this it can be argued that the sky is not blue at all. Just to our eyes.

b is correct, light gets scattered by gas molecules and blue/violet get scattered the most.
c is wrong, refraction is the bending of light when it hits a different medium. The bending of light when moving from different layers of the atmosphere is negligible. And it wouldn't bend different colors by different amounts.
Wow! There are so many "Report Abuse" answers here that i don't know the relation to the question ;=)
My answer is 'B' because I don't think 'C and A' are correct for the following reasons:
On 'A' ,The effect will be dimming of the light because the absorption will affect the intensity of light and not the color.
On 'C', Refraction of light will only shift the entire spectrum of light.
