Exploring Basic Landforms

The video explains how weathering, erosion, and deposition gradually change landscapes by forming landforms like sand dunes, canyons, deltas, U-shaped valleys, and caves. It describes the role of wind, water, glaciers, and ice in these processes, emphasizing the slow nature of these changes over time.
