Exploring Weathering, Erosion, and Deposition

The video explores the dynamic processes of weathering, erosion, and deposition that shape Earth's landforms. It explains how natural forces like water, wind, ice, and gravity contribute to these processes, altering landscapes over time. The video also highlights human impact on these natural processes and concludes with a call to learn more about Earth's ever-changing surface.
