The largest waterfall in North America is Niagara Falls, which straddles the border between the United States and Canada. It consists of three waterfalls: the Horseshoe Falls, the American Falls, and the Bridal Veil Falls. Niagara Falls has an impressive height of about 167 feet (51 meters) and a massive flow rate, with millions of gallons of water cascading over the edge every minute. It is a popular tourist destination, attracting millions of visitors each year who come to witness its breathtaking beauty and listen to the thundering roar of the water. The falls have also been harnessed for hydroelectric power.
