How does Niagara falls retreat?
Niagara Falls retreats as water flows it picks up loose rock, sand and dirt; eroding the surface back upstream.

How Niagara Falls form?
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.
What The different types of sedimentary rock exposed in the side of the Niagara falls gorge?
limestone, shale, and sandstone
How did Niagara falls form and develop?
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. == ==
When was Niagara Falls built?
The first bridge was built over the Falls in 1848. In 1969 a temporary dam was built to clear away rock debris, later other areas were filled in (1955) or permanently dammed (1980s). The Falls themselves, however, are a natural occurrence, and were not originally built by any mortal man. :)
How does weathering erosion and deposition effect Niagara Falls?
Erosion occurs to Niagara Falls becaust there is a vast amount of water flowing over the edge and it rubs against the edge causing pieces to fall off.
Which major type of rock makes up niagara falls?
The rocks that make up Niagara Falls are primarily composed of dolostone, a type of sedimentary rock that was formed from the compression of layers of limestone over millions of years. These rocks were deposited during the Silurian Period approximately 420 million years ago.
Is Niagara Falls located in Canada or the US?
The term "America" refers to the continents of North America and South America. Niagara Falls is in North America. Canada is also in North America. The term "Niagara Falls" has more than one meaning. There are actually three falls that constitute the waterway collectively called Niagara Falls. They are the magnificent "Horseshoe Falls," which is almost entirely within Canada, as well as the lesser "American Falls" and the small "Bridal Veil Falls, both of which are in the US. There are also two cities named "Niagara Falls." One is in the State of New York, in the US, and the other (the larger) is in the Province of Ontario, Canada.
