Niagara Falls Niagara Falls a complex of waterfalls on the river Niagara, located on the border of the United States and Canada.It is located on the connecting Lake Erie and Ontario (and separating the US state New York from Canada) the Niagara River about thirty kilometers from the city of Buffalo. The height of the ledge of Niagara Falls is 53 m. Niagara Falls is considered one of the most powerful in the world, a huge mass of water passes through it. The noise of the waterfall can be heard at a distance of 25 km, and near the roar of the water is so strong that you can not hear a human voice. No wonder the word "Niagara "means"rumbling water" in Indian. The retreat of the falls The waters of the Niagara River gradually erode the ledge of Niagara Falls. The rocks that make up the ledge break off and are carried downstream by the water. So, in the summer of 1956, as a result of erosion, a significant part of the ledge collapsed. A large power plant built near the waterfall was destroyed. Experts believe that the waterfall annually retreats upstream by an average of 1 m. Thus, in 20 thousand years, the waterfall will disappear.
