why is the sky blue?

Answer 1

It's red here on Mars.

Answer 2

The air in the atmosphere helps to scatter the light coming from the Sun. Colours with long wavelengths (like red) are barely scattered and just pass through, but those with shorter wavelengths (like blue) are reflected toward the earth's surface. When the Sun is close to the horizon, the long wavelengths can pass straight to the surface, while the shorter ones are reflected. Although the shortest wavelength colour is violet, the sky is not violet as our eyes are not tuned enough to see violet in the presence of longer wavelengths like blue.

Answer 3

Dr Jeep as it.
Molecules of air etc, tend to scatter all wave lengths of light to differing degrees: the amount of scattering depends on the fourth power of the frequency of light involved. Blue, indigo and violet light is scattered to a greater extent than the rest. The net affect of the combined light being scattered is the pleasant sky blue colour.

Answer 4

The sun reflects off the sea to make the sky blue and off the sky which makes the sea blue. The blueness of the sea also depends on the currents which churn up the sand and cuase waves - hence the caribbean being so clear as opposed to the African coast.

Answer 5

because at the height the sun is to the Earth, the light is slowed by the air to show us mainly the blue of the colour spectrum and that why it appears orange and red as the sun is setting in the horizon as there is a greater distance through the air and the light slows slightly more.

It does not reflect off the sea, have you ever run a tap, water is clear!!

Answer 6

Because of an effect called 'Rayleigh scattering'. Blue is a high frequency colour, therefore it scatters more than other colours giving you the blue sky you see on a clear day. Basically.

Answer 7

i think the different layers of the earth's atmosphere causes some kind of a spectrum allowing the the colour blue with the lowest wavelength to shine through which probable accounts for the fact why the colour red shines through when the sun is setting because of it's highest wavelength of the spectrum. (forgive me if I'm wrong)

Answer 8

the sky is blue because of the water quantity on the earth which reflect the ray of light which is blue because if we did not have blue colors we would see black and white because of the sun and the stars and the moon

Answer 9

Reflection of the sea! You cannot seriously believe this!

Its caused by refraction (not reflection) of light, similar to how rainbows are caused. the light emitting from the sun is 'bent' by entering the atmosphere of earth from the vacuum of space and the product of this refraction is the blue scale of the light spectrum.

Answer 10

Depressed.

Answer 11

why is the sky called SKY?
