How was the Niagara Falls formed?

Answer 1

The Niagara falls were created at the end of the Wisconsin glaciations about 10,000 years ago. When the ice melted, the Great Lakes drained over the Niagara Escarpment, along the Niagara River. The River 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 eroded away, leaving the harder rock unsupported. The unsupported top rocks gave way again and again creating a sharp edge for the falls. If the entire formation had been made of softer rock the Falls would have become rapids.

Answer 2

Niagara Falls were formed when glaciers receded at the end of the Wisconsin glaciation (the last ice age), and water from the newly formed Great Lakes carved a path through the Niagara Escarpment en route to the Atlantic Ocean. While not exceptionally high, the Niagara Falls are very wide. More than 6 million cubic feet (168,000 m³) of water falls over the crest line every minute in high flow,[1] and almost 4 million cubic feet (110,000 m³) on average. It is the most powerful waterfall in North America

Answer 3

Niagara Falls started some 10,000 years ago in the Wisconsin glaciation period. Both the North American Great Lakes and the Niagara River are the results of this last continental ice sheet, a huge glacier that swept across the area from eastern Canada...

Answer 4

from an earthquake. Or probably erosion cutting through limestone. Like the way the Grand Canyon was made.

the same way other water falls were formed

By fish.

because somthin happened
