Why is there gorges at Niagara falls?

Gorges at Niagara falls were formed by the erosive power of water over thousands of years. As the falls eroded the soft rock beneath them, they gradually receded upstream, creating a deep gorge. The combination of glacial activity and the flow of the Niagara River contributed to the shaping of the landscape, resulting in the dramatic cliffs and gorges we see today. This ongoing erosion continues to shape the falls and the surrounding area.
