All rivers carry some dirt in them as they flow. So as the Niagara river goes over the Falls, there would be some dirt in the water.
About 3.24 billion (3.24*1010) gallons of water per day flows over Niagara Falls.
It is close to 140 acres, but of the over 400 acres in Niagara Falls State Park (Niagara Falls) is under the water.
The Niagara Escarpment, a long tall cliff that the Niagara falls goes over.
water flowing over rocks and glaciers did it too
The average flow rate of water over the lip of Niagara Falls is 202,000 cubic feet per second or 5,720 meters cubed per second. This rate increases in wet seasons while tapering in drier or colder seasons. Speed wise, in easier to relate terms, the water is moving over the falls at 32 kilometers per hour, or 20 miles per hour. Specifically, the Canadian/Horseshoe falls goes at 32kph, but the American falls I don't know.
Water. ; )Well, the Niagara Escarpment also has something to do with it too. Its a long tall ridge-line separating Lake Ontario and Lake Eire. It was formed due to unequal erosion. The Niagara River flows between the lakes and goes over the edge of the cliff.
Six million cubic feet (168,000 cubic meters) of water flow over the crest every minute during high flow.
because the water splashes up
Niagara Falls --- IS --- a cliff.... that's what makes a waterfall. A waterfall is a place where water flows over the edge of a cliff.
