why is the sky blue?

Answer 1

because the grass is pink

Answer 2

The sky is blue because of the scattering of light as mentioned before, apparently. Blue light is scattered more than other colours so its refracted down here, or its the other way around, lol.
Thats why people are finding out the sky on mars, viewed from the surface is also blue, aperantly. Unless theres a sandstorm, or the colours used in processing are not correct, then it appears red.

Answer 3

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 4

On a clear sunny day, the sky above us looks bright blue. In the evening, the sunset puts on a brilliant show of reds, pinks and oranges. Why is the sky blue? What makes the sunset red?

To answer these questions, we must learn about light, and the Earth's atmosphere @ http://www.sciencemadesimple.com/sky_blue.html

Answer 5

Have you got the doubt that why sea is also blue?

Most part of the earth contains water rather than land actually sky is black it appears to be blue because of the radiation of sun light which falls on the water and appears in such a way

Answer 6

The sky is blue due the scattering effect of light. As Sunlight travels through the earths atmosphere, it gets scattered by large no. of molecules present. It basically represents change in direction.

Rayleigh, a scientist said intensity of scattered light is inversely proprtional to fourth power of its wavelenght. Since BLUE colour HAS MINIMUM WAVELENGHT IT SCATTERS THE MOST giving sky its color. need more ?http://en.wikipedia.org/wiki/Rayleigh_scattering

Answer 7

Water in the seas and oceans absorbs all color except blue. This blue color is reflected upward. The atmosphere then reflects it back to earth. That's why we see the sky as blue.

Although when my lady asks me that question, I always say, "To match the blue in your eyes."

Answer 8

when i was in school...some 18 years before, the same question i asked from my teacher and she replied. that there are allot of dust, water and gases in the air /space about earth and all that combination gives a blue shad.. that's why sky look blue from earth.
