Niagara Falls is made up of three different falls: Bridal Veil Falls, Horseshoe Falls, and the American Falls. Niagara Falls is only 12,000 years old. It was created by the glaciers pressing down on the land and gouging out the surface, and then melting and releasing large amounts of water.

Niagara Falls has eroded 11.4 kilometers (7.1 miles) during the last 12,300 years. The slowing of the erosion rate is caused by two major factors: The limestone cap rock, which the water is currently flowing over, is more resistant to erosion. This limestone layer began approximately 0.5 kilometer north of the Rainbow Bridge.

A few days around midsummer - at the Dock kan kraftig erosion uppstå stötvis i samband med kraftiga stormar.

Niagara Falls split into two distinct waterfalls some time before 1678 as the flow of the Niagara River went around Goat Island. Over the last 12,000 years erosion of the resistant rocks that cap Niagara has allowed the Falls to migrate about 7 miles upstream, and form the high-walled Niagara Gorge along its former path. Even today, Niagara Falls is estimated to be migrating upstream, on the order of one foot per year.

Therefore, the earth is not more than 10,000 years old. Source: As the Niagara Falls display the highest flow rate in all of North America, the rate of erosion occurring to the rocky surface of the falls is also incredibly high. Depending on the type of rock the rate of erosion fluctuates, historically the rate of erosion is about a meter per year; however, in the last 200 it has been retreating from Lake Ontario towards Lake Erie at a rate of 1.5 meters per year.

The slowing of the erosion rate is caused by two major factors: The development of hydro electric generating plants through water diversion along the shoreline of the Niagara River has vastly reduced the rate of water flow. Similarly, is Niagara Falls moving As the Niagara Falls display the highest flow rate in all of North America, the rate of erosion occurring to the rocky surface of the falls is also incredibly high. Depending on the type of rock the rate of erosion fluctuates, historically the rate of erosion is about a meter per year; however, in the last 200 it has been retreating from Lake Ontario towards Lake Erie at a rate of 1.5 meters The Horseshoe Falls will notch back for about 15,000 years, traveling back about four miles to a softer riverbed (from the southern end of Navy Island to Buffalo/Fort Erie the riverbed is no longer the erosion-resistant limestone but soft Salina shale) after which the rate of erosion will change significantly (remember the bedrock tilts downward to Lake Erie). Niagara Falls / n aɪ ˈ æ ɡ r ə, n aɪ ˈ æ ɡ ə r ə / is a group of three waterfalls at the southern end of Niagara Gorge, spanning the border between the province of Ontario in Canada and the state of New York in the United States. The rim of Niagara Falls erodes at four to five feet per year, indicating that it could not be more than 10,000 years old.
