Why is the sky blue?

Answer 1

The answer to this question is fairly simple. The blue sky is a result of a phenomenon called Rayleigh Scattering. The air molecules scatter the colors of the sun's light differently, depending on wavelength. The blue portion of the solar spectrum predominates in the light we see in the sky.

On Mars, vast amounts of dust in the atmosphere produce scattering of the longer (red) wavelengths of light, rather like a perpetual sunset. That is why the sky looks orange on Mars, while the sky looks blue on Earth.

Answer 2

The sky is blue because of the oxygen which, believe it or not, is sky blue in color.
Now, this may seem to be a bit unbelievable. You can look across the room and see that the other side of the room isn't bluer that the side you are one, and you are right. There simply isn't enough oxygen in the room to look blue.
When you are looking at the atmosphere, there are miles and miles of air that you are looking through, and all of this oxygen when lit up by a really bright light source (the Sun!) looks blue.
If you look straight up on a clear day, you will see that the sky is dark blue, while the edges (towards the horizon) are light blue. When you look up, you are looking at a thinner layer of air than if you looked at the horizon, and it will be less light blue (if that makes any sense), or darker.
This also explains why sunsets are red: all of the blue has been scattered (reflected) by the oxygen and dust in the air, leaving only the reds and oranges to reach you.
Why is oxygen blue? It has to do with its size, and an effect called Rayleigh scattering.
But the bottom line is: "The sky is blue because that's the color of oxygen!"

Answer 3

A clear cloudless day-time sky is blue because molecules in the air scatter blue light from the sun more than they scatter red light. When we look towards the sun at sunset, we see red and orange colours because the blue light has been scattered out and away from the line of sight.
The white light from the sun is a mixture of all colours of the rainbow. This was demonstrated by Isaac Newton, who used a prism to separate the different colours and so form a spectrum. The colours of light are distinguished by their different wavelengths. The visible part of the spectrum ranges from red light with a wavelength of about 720 nm, to violet with a wavelength of about 380 nm, with orange, yellow, green, blue and indigo between. The three different types of colour receptors in the retina of the human eye respond most strongly to red, green and blue wavelengths, giving us our colour vision.

Answer 4

Blue light is more likely to be scattered in the atmosphere than other colours.

Answer 5

cuz sky just had a huge fight with land cuz land seems to be spending all the savings on clothes she doesnt need from Kholes.

2 points!

Answer 6

atmosphere scatters blue colour the most

Answer 7

It is due to the reflective quality of the mix of gases in the atmosphere.

Answer 8

Because God made it that way

Answer 9

because the ocean.
