Well i know nothing about this but i do know that snow and rain are both forms of water and they both can in difficult situations can be used as a source for hydration though it it is not supposed to be the first choice for hydration. obviously they are different because snow can be shaped into many things if you have patience, skill, and time, but water is a complete liquid and cannot be formed into things. As im typing im forgetting a lot so i hope this was useful and im sorry for not knowing about this stuff yet.
