User: Why is the water from the American side of the falls colder than the water from the Canadian side?
Assistant: The reason is that the American side is closer to the equator than the Canadian side. The water in the Niagara River flows from the Great Lakes to the Niagara River. The water from the Great Lakes is colder because the water in the Great Lakes is not as salty as the water in the Atlantic Ocean. The water from the Atlantic Ocean is colder because it is moving faster, and the water from the Great Lakes is moving slower.
