Because The Snow is freezing up and because the snow is getting ice on it.
Snow is caused by freezing temperatures.
Sometimes the snow can reflect light to your eyes that make you see the snow sparkle.
Like a river- a catchment area (for snow) Unlike a river- constantly freezing, or near-freezing temperatures
Moisture. Wet snow contains more water in liquid form, which allows it to bond and "stick" with other snow. This type of snow is common when snow falls at temperatures near freezing. Dryer snow does not stick together because it is almost entirely ice crystals, and this type of snow falls at colder temperatures.
snow is shiny because the ice inside it is shiny
Snow is caused by freezing temperatures.
Combine snow with freezing temperatures with wind, and you get a blizzard.
When it is 80 degrees outside there will be no snow. In order for it to snow and stay around is for temperatures to be below freezing.
Freezing temperatures solidify airborne vapor particles.
Sometimes the snow can reflect light to your eyes that make you see the snow sparkle.
freezing rain
Snow in the shade potentially hasn't melted or metamorphized yet, if temperatures are below freezing. In the sun, the additional heat from radiation will be enough to melt the snow on the surface, which then refreezes because the temperature is below freezing.
