Ice and Water are the same thing, except ice is just solidified. Ice itself also doesn't freeze water, but is the transfer of temperature from one to the other. This takes a long time, in water's case, since it's so heavily influenced by its environment's temperature (In other words, water won't freeze form ice or snow unless it's in a naturally cold place, like the arctic).
Imagine a blizzard being fired at the ocean, then imagine a wave of water smashing against a pile of snow. It's plain to see that Water has a natural advantage over Ice, since it has no consistency and can't break, since it's a liquid.
It's mostly a Scientific factor, but really, when you look at it like that, it only makes sense.
