Waterfalls and Gorges

The video explains various erosional landforms, focusing on processes like attrition, abrasion, hydraulic action, and corrosion. It describes how these processes shape river landscapes, forming features such as V-shaped valleys, rapids, interlocking spurs, waterfalls, and gorges. The video highlights the role of rock types and water flow in these formations.
