I WONDER- How Are Waterfalls Formed?

Waterfalls form when a river encounters a sudden landscape change, often due to a harder rock band. The softer downstream rocks erode over time, creating a drop known as a waterfall. This erosion process continues over millennia, causing the waterfall to move upstream and carve out a gorge.
