Question

It is snowing outside and i have a question: why is snow white if water is colourless?​

Answer 1

hey mate..
This is your answer--

There’s a scientific reason that snow is white. Light is scattered and bounces off the ice crystals in the snow. The reflected light includes all the colors, which, together, look white. 

Hope it helped:-):-):-)

Answer 2

I believe the difference is that snow is made up of a bunch of small water crystals where big blocks of ice are not. All the crystals in the snow would tend to reflect the light in all sorts of directions with the net effect that a lot of the light that hits a pile of snow is reflected, making the snow look white. With ice, more of the light is transmitted through which makes the ice seem colorless.
