Salt for Snowy Conditions

Today, I talked over the phone with my friend from Siberia. We were discussing the difference in the weather in our countries, and I asked him what does he do when they get heavy snow storms (we don't get snow from where I come from).  He said that something very useful is to throw salt on the snow and ice so that it melts. The reason why this works is because salt lowers the freezing point of water, interrupting the change in phase. After the salt touches the snow, the snow's freezing point decreases causing the snow to freeze at lower temperatures. Therefore, after the snow melts, it will no longer refreeze unless it goes through an even lower temperature. I'll be sure to talk lots of salt with me if I ever visit him in Russia during the winter time!
