why is the sky blue during the day on the earth but always black on the moon?

Answer 1

the Moon has little or no atmosphere, which is needed to make a blue sky.

Answer 2

Its caused by the diffusion of light waves through nitrogen in the earths atmosphere. Since the atmosphere is mainly nitrogen (79%) that is why the sky on earth is blue. There is no atmosphere on the moon so the light travels directly to the surface.

Answer 3

The short answer is that the moon has no atmosphere, but the earth has. The longer answer is that reflected light from dust particles in our atmosphere, favors blue light rather than the other colors in the spectrum. The full answer on why this is so runs to four pages on ask.com

Answer 4

Its caused by sunlight passing through the molecules in the air. The blue part of the spectrum gets spread causing the blue hue. There's no air on the moon so no molecules.

At dusk, the angle of the sun causes light to refract though the red part of the spectrum.

It was thought the colours were caused by moisture in the air but this has recently been disproved.

Answer 5

The blue shade of the sky, as considered from earth, is a results of sunlight passing in the path of the earth's surroundings. The result's termed "scattering". easy has distinctive wavelengths (i.e. crimson easy has long wavelengths, blue easy has short wavelengths). Selective scattering happens whilst the debris (subsequently, debris in the earth's surroundings, it is made out of gasses, airborne dirt and dust, and water) are smaller than the wavelengths's hues. In Earth's surroundings, blue easy scatters and could become seen to the attention. issues like pollutants, and prefer airborne dirt and dust debris from volcanic eruptions, can exchange this "scatter" and reason the sky to look distinctive hues.

Answer 6

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 7

The moon has no atmosphere. Our air reflects the blue wavelength of light back to us, but there's no atmosphere to reflect anything back to the moon, so the sky looks black from there.

Answer 8

For the same reason that the world around you looks brown if you wear brown tinted sunglasses or green if you wear bottle green sunglasses. Whatever the air is composed of, a lot of it (air) refract the light with a light bluish colour effect. Other gases would give us a different colour 'sky'. On Mars, the 'sky'; is pinkish even at noon because of its composition.
On the Moon, with the total absence of an atmoshphere, ie. no coloured gases at all, you can see space unaltered reality or... BLACK because black is the absence of all light/colour.

Answer 9

This question comes up every day on Answers-------
Water vapor in Earth's atmosphere captures the long wave BLUE light and then re- emits it --------- the other colors mostly pass right through to the ground.

The moon is a vacuum without ANY atmosphere of any kind.

Answer 10

There's no air for the sun to reflect off like when you see a rainbow the sun shines through water particles around the shape of the earth.
