How the processes creating the falls will affect human activity in the future?
about the niagara falls
Answers:
What do you mean by "creating the falls"?
There is a fall whenever water from a high place flows down abruptly to a lower place. This flow creates erosion, and the fall recedes over time (over 11 km in the last 12000 years). The rate has recently slowed down because humans activity has reduced the flow by diverting some water to a power station, and because the fall is now over a pocket of harder rock that takes longer to erode.
The fall was created by the result of land masses moving around, creating hills and mountains, glacier moving about during the last ice age, the weight of the ice cap at that time, and so on. If such geological activities were to continue in the future (they do and they will) then human activity is certainly going to be affected over time, making some area unsuitable for living. Such changes take place over thousand and million of years, so there is no real panic.
Niagara will eventually run its course because it is slowly losing ground for water to Fall.
