How are waterfalls made by glaciation?

Answer 1

Waterfalls formed by glaciation typically occur when a glacier carves out a valley, creating a steep drop-off as it retreats. As the glacier moves, it erodes the rock beneath it, often leaving behind a hard rock layer that resists erosion. When the glacier melts, rivers may flow over these ledges, creating waterfalls where the water cascades over the steep terrain. This process can result in dramatic landscapes, with waterfalls often found at the edges of glacially carved valleys.
