Answer:
Niagara Falls, although are not the highest in the world, are famous for their breadth and flow, in addition to serving as a natural border between the United States and Canada, in the eastern part of North America.
The American side of the falls is located in New York with the "American Falls" and the smaller ones, the "Bridal Veil Falls", while the Canadian side is in Ontario with the "Canadian Falls" also known as "Horseshoe Falls".
It should be noted that these impressive waterfalls were formed in the last Earth glaciation and the water that flows through them comes from four large lakes and then flows down the Niagara River to Lake Ontario, following the St. Lawrence River to empty into the Atlantic Ocean .
