Moisture content
More in the winter and less in the summer.

They have both done the same amount of work. But the snow blower has more power and does the same job in less time.
Yes with Snow tires ( if you live in a region with snow during winter ) but with no more then 2 inches of snow or less you will get stuck or have no traction
Since you are at a higher elevation the suns rays are more intense, this is why you will get sun burnt. Snow blindness happens because the light reflects of the snow and makes it more bright.
It is better to have less friction because it will be easier to get out.
All natural water is more or less acidic.
Yes, because the snow has more mass. One gram of water will turn into one gram of snow -- there is no mass lost or gained by the conversion. (OK, maybe a little because of movement... relativity and all that stuff that is not yet measurable. Anyway, relativistically speaking, the snow would have a smaller mass because it moves slower.)

More than average but less than last year
It is better to have less friction when a car tire gets stuck in mud or snow because less friction allows the tire to spin more easily and gain traction to get out of the obstacle. Increasing friction in these situations can worsen the situation by making the tire more likely to dig into the mud or snow.
Yes but it is not very predictable. Sereral years of heavy snow in the winter might be followed by serveral years of no snow at all. Generaly there is more snow in the North and less in the South. Some of the highest peaks in Scotland may see snow on them all year round. The whole of Scotland as a whole has more snow than the rest of the UK.
