Which is most likely an example of a heat source?

1. Lake Ontario on a clear fall night
2. an iceberg in the North Atlantic Ocean
3. a desert waterhole on a sunny summer day
4. a Rocky Mountain glacier in August
 
Lake Ontario on a clear fall night. You want to know why? It's the best answer out of the given, because on a fall night, the water in Lake Ontario would be warmer than the surrounding air. That would force it to give off heat to get to an equilibrium temperature with the outside air. Ten Points Please! :)
