The Niagara River in Niagara Falls connects two of the five Great Lakes of North America, Lake Ontario and Lake Erie, and because of the huge gap between the two lakes, the Niagara River handles this gap directly and simply and crudely with cliffs, So Niagara Falls was formed. The huge currents flow from Lake Erie to Lake Ontario, separated by the Niagara River by Goat Island on one side of the United States, forming two waterfalls, the United States Falls in the United States and the Horseshoe Falls in Canada. More than 90% of the currents roar down from the Horseshoe Falls on the Canadian side, forming a huge water mist, and the close look is awe-inspiring. The American Falls have less than 10% of the currents, but they are also spectacular. In the United States, Niagara Falls can only be viewed from the side, and only from Canada can the entire view of the two major falls be seen at a glance.
