  2. Niagara Falls - Wikipedia

    en.wikipedia.org/wiki/Niagara_Falls

    The current rate of erosion is approximately 30 centimeters (0.98 feet) per year, down from a historical average of 0.9 m (3.0 ft) per year. At this rate, in about 50,000 years Niagara Falls will have eroded the remaining 32 km (20 mi) to Lake Erie, and the falls will cease to exist. [8] [17] [18]

  3. Knickpoint - Wikipedia

    en.wikipedia.org/wiki/Knickpoint

    The Horseshoe Falls, one of the three Niagara Falls.The falls are a knickpoint, formed by slower erosion above the falls than below. In geomorphology, a knickpoint or nickpoint is part of a river or channel where there is a sharp change in channel bed slope, such as a waterfall or lake.

  4. Niagara Gorge - Wikipedia

    en.wikipedia.org/wiki/Niagara_Gorge

    Niagara Gorge is an 11 km (6.8 mi) long canyon carved by the Niagara River along the Canada–United States border, between the U.S. state of New York and the Canadian province of Ontario. [1] It begins at the base of Niagara Falls and ends downriver at the edge of the geological formation known as the Niagara Escarpment near Queenston, Ontario ...

  6. Niagara River - Wikipedia

    en.wikipedia.org/wiki/Niagara_River

    The Niagara Gorge, downstream from the falls, includes the Niagara Whirlpool and additional rapids. Power plants on the river include the Sir Adam Beck Hydroelectric Generating Stations (built in 1922 and 1954) on the Canadian side, and the Robert Moses Niagara Power Plant (built in 1961) on the American side, collectively generating 4.4 ...

  7. Caprock - Wikipedia

    en.wikipedia.org/wiki/Caprock

    At Niagara Falls, the caprock is the riverbed above the falls, and is what prevents the river from eroding the face of the falls very quickly. The Niagara caprock is made of dolomitic limestone. Other common types of caprock are sandstone and mafic rock. In processes such as scarp retreat, the caprock controls the rate of erosion of the scarp ...

  8. River rejuvenation - Wikipedia

    en.wikipedia.org/wiki/River_rejuvenation

    The process is often a result of a sudden fall in sea level or the rise of land. The disturbance enables a rise in the river's gravitational potential energy change per unit distance, increasing its riverbed erosion rate. The erosion occurs as a result of the river adjusting to its new base level. [1]

  9. Geology of Ontario - Wikipedia

    en.wikipedia.org/wiki/Geology_of_Ontario

    The current rate of erosion is approximately 30 centimeters (1 ft) per year, down from a historical average of 0.91 m (3 ft) per year. According to the timeline of the far future, in roughly 50,000 years Niagara Falls will have eroded the remaining 32 kilometres (20 mi) to Lake Erie and ceased to exist. [21]
