4. Niagara Falls
- Location
Location
The Niagara Falls are between Lake Erie and Lake Ontario, on the
border between Canada and the USA. The falls are partly in Canada
and partly in the USA and they are separated by Goat Island.
5. What is it Like? Views
The river flows along transporting material before plunging down a 50
metre cliff! At the bottom of the cliff the water has worn away the
softer rock to form a pool over 50 metres deep. This is called a plunge
pool.
6. How was it formed?
In this area, a band of hard
limestone lies on top of
softer shales and sandstone.
7. How has it changed over time?
Over time the falls have created the Niagara Gorge. The falls are eating into the
cliffs behind at nearly 1 metre a year! The gorge that is left behind is now 11
kilometres long.
