why is the sky blue?

Answer 1

Because I like blue and I told God to make it Blue for me.
Plus the other reason it's blue. Water and ice in the edge of space and the sun light hitting it makes it look blue. Or else all you would see was black of space.

Answer 2

Here is something interesting to think about: When you look at the sky at night, it is black, with the stars and the moon forming points of light on that black background. So why is it that, during the day, the sky does not remain black with the sun acting as another point of light? Why does the daytime sky turn a bright blue and the stars disappear?

The first thing to recognize is that the sun is an extremely bright source of light -- much brighter than the moon. The second thing to recognize is that the atoms of nitrogen and oxygen in the atmosphere have an effect on the sunlight that passes through them.

There is a physical phenomenon called Rayleigh scattering that causes light to scatter when it passes through particles that have a diameter one-tenth that of the wavelength (color) of the light. Sunlight is made up of all different colors of light, but because of the elements in the atmosphere the color blue is scattered much more efficiently than the other colors.

So when you look at the sky on a clear day, you can see the sun as a bright disk. The blueness you see everywhere else is all of the atoms in the atmosphere scattering blue light toward you. (Because red light, yellow light, green light and the other colors aren't scattered nearly as well, you see the sky as blue.)

Answer 3

The sky is blue because of the water in the air. It is not a reflection from the ocean because 1) What is reflecting it back? and 2) Why would it be blue even over the areas like the desert?

Answer 4

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.

Answer 5

looking at some of the answers i feel so bad but most people say that the solar winds bouncing off the atmosphere and the pollution have made the sky blue

Answer 6

What we have been taught, is to see the word blue when we look at the sky. What each person perceives as blue is and always will be a mystery.

Answer 7

The sky is blue because it reflects off the water.

Answer 8

The ozone layer, surronding the earth above the sky, is a shade of blue.

Answer 9

Because of diffuse sky radiation.

Sky radiation-->Diffuse sky radiation is solar radiation reaching the earth's surface after having been scattered from the direct solar beam by molecules or suspensoids in the atmosphere. Also called skylight, diffuse skylight, or sky radiation.

Answer 10

first you must understand that there is no sky only space.

the earth is a bubble protected by the atomosphere. When the sun shines on this it "lights the space in view through our "tinted" lenses known as ozone there for space looks blue
