How did Niagara falls form and develop?

Answer 1

The Niagara falls were created at the end of the Wisconsin glaciation about 10,000 years ago. When the ice melted, the Great Lakes drained over the Niagara Escarpment by way of the Niagara River. The River initially cut a gorge through the escarpment. The layers of rock in the escarpment have a top rock formation that is composed of harder stone that eroded more slowly than the underlying materials. The softer rock preferentially eroded away, undercutting the harder rock. The unsupported top rocks gave way from time to time creating a sharp edge for the falls.

If the entire formation had been softer rock the present Falls would have been reduced to a series of rapids.

Answer 2

Niagara Falls was made by a combination of the last ice age and erosion. During the last ice age, a tremendous amount of ice built up in the area of Wisconsin, depressing that area. The pressure resulted in the formation of the Niagara Escarpment. When the ice age ended, the Niagara River flowed over the escarpment, which is near Lake Ontario. Thousands of years of erosion resulted in the falls being at the present location.

Answer 3

Niagara Falls were formed during the last ice age (the Wiscosin glaciation).

Answer 4

The water comes from all the Great Lakes, then down the Niagara River and then falls over the Niagara Falls.
