I have a small waterfall and a pond in my backyard. In the summer, it helps cool the temperature of the pond, but in the winter, even when the pond is mostly frozen, the waterfall is not. If the energy from the moving water is keeping it from freezing (I assume...), why does it cool in the summer? Is it because the air around it is actually cooler than the water in the summer? If so, why is the water in summer warmer than the surrounding air? :) Thanks!
