Why does it snow?

My daughter asked that question today. It snowed about 3 inches and I was blowing away the snow on the drive way. My kids were excited to come out and play on the snow. They were running around on the lawn covered with the white stuff, making snow man, making snow ball to throw at each other. They always have a blast when it snows. But I have to make sure the drive way is clean so we can get the car out easily.

When I heard that question, in my own geeky way I asked her back the questions, well...why does it rain? why is there an ocean? why do plants grow? why are we here? She looked at me strangely and said, so we don't know any of those? I nodded with a smile. She replied quickly, as if it was pretty obvious to her. "I think it snows so children can play and grownups can get a work out!" She went back to play. That was good enough answer for her! :-)
