Niagara Falls

Niagara Falls is a famous area of waterfalls. It is one of the most beautiful natural wonders of North America. It is on the Niagara River, about halfway between Lake Erie and Lake Ontario. The Niagara River forms part of the border between Canada and the United States. At Niagara Falls, Ontario, Canada is on one side of the river, and the U.S. state of New York is on the other side.
Niagara Falls really has two waterfalls. The Horseshoe Falls are in Canada, and the American Falls are in the United States.
The Niagara River drops into a steep gorge or canyon, at the falls. Most of the water flows over the Horseshoe Falls. They are not as high as the American Falls, but they are 2,600 feet (792 metres) wide–about 0.5 mile (0.8 kilometre). The American Falls are about 1,000 feet (305 metres) wide.
Beyond the falls are the Whirlpool Rapids. There, the powerful swirling water has carved a bowl out of the rock.
At night, coloured lights shine on the thundering falls. About 10 million people visit Niagara Falls each year.
